This TP4056 1A Li-ion lithium Battery Charging Module with Current Protection – Mini USB is a tiny module, perfect for charging single cell 3.7V 1 Ah or higher lithium ion (Li-Ion) cells such as 16550s that don’t have their own protection circuit. Based on the TP4056 charger IC and DW01 battery protection IC this module will offer 1A charge current then cut off when finished.

Furthermore when the battery voltage drops below 2.4V the protection IC will switch the load off to protect the cell from running at too low of a voltage – and also protects against over-voltage and reverse polarity connection (it will usually destroy itself instead of the battery) however please check you have it connected correctly the first time.

Manufactured under fully machinery processing. Each module is tested OK before shipment from  so it has high reliability for the best performance. In conclusion, it is special design for a single lithium battery charging. TP4056 Other features include the current monitor, under voltage lockout, automatic recharge, and two status pin to indicate charge termination and the presence of an input voltage.

Using the module:

1. Connect mini USB cable for power, or 5V DC to pads marked IN+ and IN- on the left-hand side of the module
2. Connect cell to charge to B+/B- pads on the right-hand side of the module.
3. A load (something for the battery to power) can be connected to the OUT+/OUT- pads on the right-hand side
4. Important! Disconnect load when charging
5. The red LED indicates charging in progress, green LED indicates charging has finished.
6. Never charge your battery at a rate greater than 1C.

NOTE:

1. Ampere meter can only be connected to a 5v input end of the module.
2. It is better than the charging current is 37% of the battery capacity. If you charge the battery of 1000mAh, a current of 400mAh is enough.
3. The connection wire should not be too thick.
4. Make sure the connect point is good.
5. If the input voltage is too high, like 5.2v, the current will be less than 1000mA, it is normal. It is protection function, auto-subtract the charging current to avoid burn damage to the chip.
6. NO Reverse polarity.

This L298 Based Motor Driver Module is a high power motor driver perfect for driving DC Motors and Stepper Motors. It uses the popular L298 motor driver IC and has the onboard 5V regulator which it can supply to an external circuit. It can control up to 4 DC motors, or 2 DC motors with directional and speed control

This motor driver is perfect for robotics and mechatronics projects and perfect for controlling motors from microcontrollers, switches, relays, etc. Perfect for driving DC and Stepper motors for micro mouse, line following robots, robot arms, etc.

An H-Bridge is a circuit that can drive a current in either polarity and be controlled by Pulse Width Modulation (PWM).

Pulse Width Modulation is a means of controlling the duration of an electronic pulse. In motors try to imagine the brush as a water wheel and electrons as the flowing droplets of water. The voltage would be the water flowing over the wheel at a constant rate, the more water flowing the higher the voltage. Motors are rated at certain voltages and can be damaged if the voltage is applied to heavily or if it is dropped quickly to slow the motor down. Thus PWM. Take the water wheel analogy and think of the water hitting it in pulses but at a constant flow. The longer the pulses the faster the wheel will turn, the shorter the pulses, the slower the water wheel will turn. Motors will last much longer and be more reliable if controlled through PWM.

 

Features:-

 

• Driver chip: L298 dual H-bridge driver chip.
• Operates up to 35V DC
• Drive part of the peak current Io: 2A / Bridge
• Logical part of the terminal power supply range Vss :4.5V-5.5V
• Logical part of the operating current range: 0 ~ 36mA
• Maximum power consumption: 20W

 

 

Pins:-

 

• Out 1: Motor A lead out
• Out 2: Motor A lead out
• Out 3: Motor B lead out
• Out 4: Mo (Can actually be from 5v-35v, just marked as 12v)
• GND: Ground
• 5v: 5v input (unnecessary if your power source is 7v-35v, if the power source is 7v-35v then it can act as a 5v out)
• EnA: Enables PWM signal for Motor A (Please see the “Arduino Sketch Considerations” section)
• In1: Enable Motor A
• In2: Enable Motor A
• In3: Enable Motor B
• In4: Enable Motor B
• EnB: Enables PWM signal for Motor B 

 

 

Usage:-

H-bridges are typically used in controlling motors speed and direction but can be used for other projects such as driving the brightness of certain lighting projects such as high powered LED arrays.

 

NOTE:-

Make sure you have all of your grounds tied together; Arduino, Power source, and the Motor Controller.

The PWM Pins are unnecessary if you do not want to control PWM features.

This brand new and Latest Digital Multimeter Small Yellow Color LCD AC DC Measuring Voltage Current is a Small Multimeter for your day to day needs. If you have basic knowledge about Multimeters you can try this small Multimeter for basic continuity checks, Voltage Measurements and many more. 

A multimeter or a multitester, also known as a VOM (Volt-Ohm meter), is an electronic measuring instrument that combines several measurement functions in one unit. A typical multimeter would include basic features such as the ability to measure voltage, current, and resistance.

Analog multimeters use a microammeter whose pointer moves over a scale calibrated for all the different measurements that can be made. Digital multimeters (DMM, DVOM) display the measured value in numerals, and may also display a bar of a length proportional to the quantity being measured. Digital multimeters are now far more common than analog ones, but analog multimeters are still preferable in some cases, for example when monitoring a rapidly-varying

As the name suggests it is the multifunction device for all your testing need for daily work. When testing DC voltage, AC voltage, DC current, resistance, diode, buzzer, and battery, connect the red test lead to “VΩmA” jack and black test lead to “COM” jack, whereas When you need to test the current more than 200mA, connect the red test lead to “‘ 10A≡” jack and black test lead to “COM” jack. And When while testing the temperature, connect the temperature probe to “VΩmA” jack or “COM” jack.

When testing the magnifying ratio of the transistor, turn the switch to hFE position and connect the transistor to the eight hole jack available in blue color. For the Square wave output, the frequency is 50Hz, the voltage is approximately 3Vp-p. The output jack is “VΩmA” and “COM”
