In this post I'll show you about the Arduino Nano board & what it does.
This is the brain of this control unit.As above image this module has 30 I/O pins.And to power up this module , we need to connect +5v power supply to the VIN(30) pin , and the ground power line to the GND(29) pin.In main control unit , all other modules are connected to this module and those all the modules will control by this Arduino board.To program this module , we have upload our arduino program to this board using Arduino IDE via a data cable.
To do that we need to follow below steps,
- Connect the Arduino board to the computer
- Open the arduino sketch(program)
- Selecting the port(Tools > Ports)
- Uploading the sketch to the board by clicking the upload button
In next post I'll show you about the ESP8622 wifi module.
