Tachometer is a RPM counter which counts the no. of rotations per minute. There are two types of tachometer - one is mechanical and the other one is digital. Here we are going to design an Arduino ...

Man, do nerds love their coffee. How else do you explain that a robot-controlled espresso machine blew through its Kickstarter target by a crazy 16X? Coffee-loving engineers Gleb Polyakov and Igor ...

After designing this line follower robot using arduino uno, I have developed this computer controlled robot. It can be controlled via the computer and we can use specific keyboard keys to move it. It ...

In this project, we create a joystick-controlled laser by connecting two servos to a joystick and using this setup as a pan-and-tilt controller for a ...
