SO we all know about Arduino. That is basically a programmer board or you can say it is a prototype board where you use that to make a prototype of your hardware. Arduino is open source platform and you can find the internal circuit or ide any whare for free. So to make an Arduino is very easy at home. if you go for the original Arduino Uno then it cost you around 23 to 24 $ . and the chipper variant or the Chinese one costs you around 10 $. So to make an Arduino is very useful, and by going through the process you get more familiar with the architecture and function of the Arduino. components:- ATmega microcontroller 8/128/328 16/12 MHz crystal. 22pf bypass capacitor. 100-ohm resistance. female or mail header pins as per your requirement. zero PCB. connecting wire. soldering kit. USB ASP For programme the controller. Procedure:- cool down your mind and heat up the soldering iron. play a decent song and start soldering the circuit board properly as per the dia
