2. Operating Voltage: 12V
3. Maximum Voltage- Umax (V) : 15V
4. Maximum Current- Imax (A) : 5.2A
5. Maximum Power : 54 W
6. Power Cord: 25cm

The TEC1-12705 40x40mm Thermoelectric Cooler 5A Peltier Module is the simple application of Peltier Thermoelectric Effect. The module features 127 semiconductor couples in the area of 40mmx40mm which very effectively cools and heats up to 80°C.

Thermoelectric coolers also are known as TEC or Peltier Module create a temperature differential on each side. One side gets hot and the other side gets cool. Therefore, they can be used to either warm something up or cool something down, depending on which side you use. You can also take advantage of a temperature differential to generate electricity.

This Peltier works very well as long as you remove the heat from the hot side. After turning on the device, the hot side will heat quickly, the cold side will cool quickly. If you do not remove the heat from the hot side (with a heat sink or other device), the Peltier will quickly reach stasis and do nothing. We recommend using an old computer CPU heatsink or another block of metal to pull heat from the hot side. We were able to use a computer power supply and CPU heatsink to make the cold side so uncomfortable we could not hold our finger to it.

A thermoelectric cooling (TEC) module is a semiconductor-based electronic component that functions as a small heat pump. By applying the DC power source to a TEC, heat will be transferred from one side of the module to the other. It creates a cold and hot side. They are widely used in industrial areas, for example, computer CPU, CCDs, portable refrigerators, medical instruments, and so on.

Also Known as Thermoelectric cooling modules, Thermoelectric modules, Peltier modules, Thermoelectric cooling module.

Operating Tips:

1. Do not exceed Imax or Vmax when operating a module.
2. Please carry out moisture protection options (sealing) in final application use.
3. Life expectancy: 200,000 hours
4. Failure rate based on longtime testings: 0.2%.

Important Note!! Heat side requires heat sink all the time. “ Do not run this device with a power supply more than a few seconds without a heatsink mounted to the device! ”

Features :

1. Small module.

If you want to add some visual output to your Arduino projects, you’ll need a display. If you need only little to display, the LCD1602 Parallel LCD Display with IIC/I2C interface is a quite good solution.

This is LCD1602 Parallel LCD Display that provides a simple and cost-effective solution for adding a 16×2 White on RGB Liquid Crystal Display into your project. The display is 16 character by 2 line display has a very clear and high contrast white text upon a blue background/backlight.

This is great blue backlight LCD display. It is fantastic for Arduino based project. This LCD1602 Parallel LCD Display with Yellow Backlight is very easy to interface with Arduino or Other Microcontrollers.

This display overcomes the drawback of LCD1602 Parallel LCD Display in which you’ll waste about 8 Pins on your Arduino for the display to get working. Luckily in this product, an I2C adapter is directly soldered right onto the pins of the display. So all you need to connect are the I2C pins, which shows a good library and little of coding.

The I2C is a type of serial bus developed by Philips, which uses two bidirectional lines, called SDA (Serial Data Line) and SCL (Serial Clock Line). Both must be connected via pulled-up resistors. The usage voltages are standard as 5V and 3.3V.

If you already have the I2C adapter soldered onto the board like in this product, the wiring is quite easy. You should usually have only four pins to hook up. VCC and GND of course. The LCD display works with 5 Volts. So we go for the 5V Pin.

The values shown on the display can be either a simple text or numerical values read by the sensors, such as temperature or pressure, or even the number of cycles that the Arduino is performing.

OLED’s are the future of displays, as they possess some of the greatest advantages over both conventional display technologies of LCD’s and LED‘s.

The most attractive thing about using the OLED displays is that they do not need a back-light like conventional LCD/LED screens. The organic material itself has a property known as Electroluminescence (EL), which causes the material to “glow” when stimulated by a current or an electric field. Best energy saving displays ever!!!

This 0.96″ OLED Display Module offers 128×64 pixel resolution. They are featuring much less thickness than LCD displays with good brightness and also produce better and true colors. 

This OLED Display Module is very compact and will add a great ever user interface experience to your Arduino project. The connection of this display with Arduino is made through the I2C(also called as IIC) serial or SPI interface.

The 0.96″ OLED Display Module produces blue text on black background with very good contrast when supplied with DC 2.8V supply. The OLED Display Modules also offers a very wide viewing angle of about greater than 160°.

Setting up SPI/I2C Connection with GMS096A OLED Module :

Being a new entry into the market, only limited resources are available on this small piece of a miracle (GMS096A). I2C/SPI configuration always demands helpful resources as in any case. For the SPI setup, the module comes in 4 wire SPI configuration by default and to make it work with the Arduino you can use these libraries from Adafruit.

For the I2C setup, it demands a little bit of work on the module, let us start with resoldering the resistor from position R3 to R1 and then short the R8 resistor with some soldering tin (0 Ohm resistor). The R6 and R7 pullup resistors are already soldered, nothing to do there. Once done, the module is ready for I2C communication! The CS Pin is not necessarily needed, so just connect it to GND. The DC Pin selects the address. For standard address wire it to GND. The RES-pin needs a low pulse at startup and a high voltage during operation (as in SPI mode), a 100nF capacitor to GND and a 10k resistor to VCC would be ideal!

The USB TO UART TTL 5V 3.3V FT232RL Download Cable To Serial Adapter Module is a basic breakout board for the FTDI FT232RL USB to serial IC, Revision 2. The pinout of this board matches the FTDI cable to work with official Arduino and cloned 5V Arduino boards. It can also be used for general serial applications.

The major difference with this board is that it brings out the DTR pin as opposed to the RTS pin of the FTDI cable. The DTR pin allows an Arduino target to auto-reset when a new Sketch is downloaded. This is a really nice feature to have and allows a sketch to be downloaded without having to hit the reset button. This board will auto reset any Arduino board that has the reset pin brought out to a 6-pin connector.

The pins labelled BLK and GRN correspond to the coloured wires on the FTDI cable. The black wire on the FTDI cable is GND, green is CTS. Use these BLK and GRN pins to align the FTDI basic board with your Arduino target.

This board has TX and RX LEDs that make it a bit better to use over the FTDI cable. You can actually see serial traffic on the LEDs to verify if the board is working.

This board was designed to decrease the cost of Arduino development and increase ease of use (the auto-reset feature rocks!). Our Arduino Pro boards and LilyPads use this type of connector.

One of the nice features of this board is a jumper on the back of the board that allows the board to be configured to either 3.3V or 5V (both power output and IO level). This board ship default to 5V, but you can cut the default trace and add a solder jumper if you need to switch to 3.3V.

The 4 x 4 matrix keypad usually is used as input in a project. It has 16 keys in total, which means the same input values. The 4 x 4 Matrix Keypad Module is a non-encoded matrix keypad consisting of 16 keys in parallel. The keys of each row and column are connected through the pins outside – pin R1-R4 as labeled beside control the rows, when L1-L4, the columns.

A 4×4 matrix keypad consisting of microswitch buttons. The module has four holes 3mm (M3) holes for mounting. The pin designations on each PCB are shown on each PCB. Four pins are thus used as an ‘x’ coordinate and the other 4 as a ‘y’ coordinate.
The module is already equipped with a soldered pin-headers.

How it Works:

First test whether any key is pressed down. Connect power to rows, so they are High level. Then set all the rows R1-R4 as Low and then detect the status of the columns. Any column of Low indicates there is key pressing and that the key is among the 4 keys of the column. If all columns are High, it means no key is pressed down. Next, locate the key. Since the column in which the pressed key lies is identified, knowing the line would finalize the testing. Thus, set the rows as Low in turns until any is unveiled accordingly – other rows will still be High.
Now the row can be identified. Detect the status of each column in turns. The column tested Low is the one intersecting with the line – their cross point is just the key pressed.

This DC 12V KK-P20/15 2.5KG Lifting Solenoid Electromagnet consists of an iron core and a coil to attract magnetic substances, using the magnetic action induced by electric current, only while the current is applied. This compact functional device offers high power with high reliability. The structure and design to release the residual magnetism left after de-energization is also one of its unique features.

Working Principle:

An electromagnet is simply a coil of wire.  It is usually wound around an iron core.  However, it could be wound around an air core, in which case it is called a solenoid.  When connected to a DC voltage or current source, the electromagnet becomes energized, creating a magnetic field just like a permanent magnet.   The magnetic flux density is proportional to the magnitude of the current flowing in the wire of the electromagnet.

We supply many varieties of electromagnets with a higher power as well as lower, original dimensions, etc to satisfy your unique requirements.

Note: Images may be seen different from actual product in terms of Dimensions

Precaution:

Electromagnets must meet the following conditions to achieve maximum suction:

1. The object to be sucked must have a good magnetic permeability.
2. Proper use of power supply, rated voltage.
3. The object to be sucked must be flat and clean.
4. The object to be sucked must be greater than or equal to the surface of the magnet( For example the magnet is 20 x 15 mm, so the surface area is S=r²π=10²π mm² so the object to be sucked must be greater than or equal to 10²π mm² )
5. The object to be sucked must be greater than 5mm. (If the thickness decreases, the suction decreases)
6. The object to be sucked must be close, the middle can’t be interspersed with objects or gaps
7. Suction means more than 5cm in thickness, surface roughness, the surface is greater than the cross-sectional area of the electromagnet and maximum suction completely fit together on an iron-based material.
8. Electromagnet in working condition electromagnetic conversion would produce a certain amount of heat, electricity more frequently the higher temperature, which is a normal phenomenon.

Features:1. Our DC-powered electromagnet generates a magnetic field of high-power with high efficiency.2. Minimized in residual magnetic.

When an electromagnet is energized, the problem is how to release the magnetic force which remains on the device after the power is turned off. Our electromagnet is designed with measures to release and minimize this residual magnetic force.

3. Lightweight, compact design for space-saving.

Compact mechanism with high reliability.

4. Long life

High mechanical strength and excellent durability.

5. Widely applied in automation: assembly line, sorting machine, mechanical arm, experimental facility, etc
