In this week, we are going to make PWM(Pulse Width Modulation) circuit. The reason to make PWM usually for the fan(the brushless one). The PWM circuit will control your motor speed.

Cheap Arduino WiFi shield with ESP8266

In my previous Instructable I have described how to plug the module into a breadboard.This is just the first step to make a cheap Arduino WiFi shield using.


The Shrimp circuit is an Arduino Uno substitute with a component cost of around one tenth the price of official Arduino boards. You can hand-make the circuit on breadboard or stripboard, learning a.
