In this instructable you'll learn how to make a remote for your robot using pushbuttons. The Arduino or whichever microcontroller you are using will read the states of these pushbuttons and can control the robot accordingly.
Step 1: Circuit Diagram
This is the circuit diagram of the remote. Each of the pushbuttons are connected to Arduino digital pins. If the button is pushed the Arduino will read it as HIGH state.
The remote uses 5V input. Resistors are placed with each pushbutton so that all the buttons don't go to HIGH state when a single button is pressed.
You can also connect this remote with an RF transmitter and control your robot wirelessly
