Arduino UNO in Bangladesh The Arduino Uno is a microcontroller board based on the ATmega328 (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller.
Solderless Large BreadboardA breadboard (or protoboard) is usually a construction base for prototyping of electronics. The term "breadboard" is commonly used to refer to a solderless breadboard (plugboard). Because the solderless breadboard for electronics does not require soldering, it is reusable. This makes it easy to use for creating temporary...

1. Ampere meter can only be connected to 5v input end of the module.
2. It is better that the charging current is 37% of the battery capacity. If you charge to the battery of 1000mAH, current of 400 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-substract the charging current to avoid burn damage to chip.
6. NO Reveral polarity.
