This is great green backlight LCD display. It is fantastic for Arduino based project. This LCD1602 LCD Display is very easy to interface with Arduino or Other Micro-controllers.

This display overcomes the drawback of LCD 1602 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.

This BMP280 is a cheapest and tiny Atmospheric Sensor Breakout to measure barometric pressure, and temperature readings all without taking up too much space. Basically, anything you need to know about atmospheric conditions you can find out from this tiny breakout. The BMP280 Breakout has been design to be used in indoor/outdoor navigation, weather forecasting, home automation, and even personal health and wellness monitoring.

This module uses an environmental sensor manufactured by Bosch with temperature, barometric pressure sensor that is the next generation upgrade to the popular BMP085/BMP180/BMP183 Sensor. This sensor is great for all sorts of weather sensing and can even be used in both I2C and SPI! This precision sensor from Bosch is the best low-cost, precision sensing solution for measuring barometric pressure with ±1 hPa absolute accuraccy, and temperature with ±1.0°C accuracy. Because pressure changes with altitude, and the pressure measurements are so good, you can also use it as an altimeter with ±1 meter accuracy.

The BMP280 is the next-generation of sensors, and is the upgrade to the BMP085/BMP180/BMP183 - with a low altitude noise of 0.25m and the same fast conversion time. It has the same specifications, but can use either I2C or SPI. For simple easy wiring, go with I2C. If you want to connect a bunch of sensors without worrying about I2C address collisions, go with SPI.

The 4 Channel Wireless Four Button RF Remote Control Transmitter Receiver Module with Non-Locking mode can be composed of a fixed code four radio receiver circuits, remote control of four four-bit data output code corresponding to the module, you can easily make up a wireless remote control receiver circuit.

They are widely applied in the majority home electronics enthusiasts, industrial remote control electronic product design and development can be very good as a single-chip signal input source, especially for students and colleges electronic circuit design, the graduate design of the remote control circuit portion.

1. There are four buttons on the remote control and respectively correspond to the four data bits to the receiving board output pin D0, D1, D2, and D3.
2. Press the buttons to transmit signals, the corresponding data bit is output high.

Caution: Take care while handling the receiver module, that onboard copper coil (inductor) should be untouched. A little physical movement to the coil changes the inductance value which may cause the inappropriate circuit functioning

How it Works:

1. When a key is pressed, the IC is connected to power supply battery and it starts transmitting packets at 315 Mhz frequency consisting of its ID and Data byte which indicates which key was pressed. This information is used in remote control applications.

2. Each transmitter has a pre-programmed unique ID set during manufacturing and cannot change. The receiver board usually stores the transmitter ID in its memory before so the receiver only responds to known transmitter IDs for secure applications.

3. The RF part inside remote is SAW based 315 Mhz transmitter, which can receive by any 315 Mhz type ASK RF Receiver followed by decoder chip.

Note: By default, this remote control module comes with a Non-Locking mode.This RF remote control comes in different operating Mode: a Non-locking Mode, a Self-Locking Mode, and an Interlocking Mode (Product included comes in Non-Locking Mode)

• Non-locking:

Output also has known jog output data pin output level is instantaneous and the transmitter and whether transmission corresponds; is useful to control similar to jogging. A remote control signal data pin is high, the signal disappears when the remote data foot immediately restored to the low level. For applications such as electric doors, electric door locks, and SCM docking requires only a high level of the circuit and other circuits and so on.

• Self-locking:

Here Data output pin enables the trigger to flip operating logic; data can keep as long as the successful reception of the corresponding level state change, until the next time the remote data changes. Self-locking independent of each other four, four simultaneous remote control, such as lighting control and the like.

• Interlocking:

The Output is anyway the road will be able to receive the signal remains high state corresponding received data in any other way is the return to the original state, only four interlockings turned all the way, practical applications such as electric fans position switch circuit.

This is ADS1115 16-Bit ADC – 4 Channel with Programmable Gain Amplifier. For micro-controllers without an analog-to-digital converter or when you want a higher-precision ADC, the ADS1115 provides 16-bit precision at 860 samples/second over I2C. The chip can be configured as 4 single-end input channels or two differential channels. As a nice bonus, it even includes a programmable gain amplifier, up to x16, to help boost up smaller single/differential signals to the full range. We like this ADC because it can run from 2V to 5V power/logic, can measure a large range of signals and it’s super easy to use. It is a great general purpose 16-bit converter.
The chip’s fairly small so it comes on a breakout board with ferrites to keep the AVDD and AGND quiet. Interfacing is done via I2C. The address can be changed to one of four options (see the datasheet table 5) so you can have up to 4 ADS1115’s connect on a single 2-wire I2C bus for 16 single end inputs.
To get you start, we have example code for both the Raspberry Pi (in our Adafruit Pi Python library) and Arduino (in our ADS1X15 Arduino library repository) Simply connect GND to ground, VDD to your logic power supply, and SCL/SDA to your microcontroller’s I2C port and run the example code to start reading data.
