Reaction Time Tester Arduino

Introduction: Reaction Time Tester Arduino

This is a simple Reaction tester that uses LED's and buttons to test how fast you can react and press the button corresponding to the correct LED that turns on. This game is similar to a popular arcade game known as whack-a-mole.

Step 1: What Will You Need?


  • Arduino
  • Breadboard
  • USB A to B Cable
  • L.E.D.
  • Push Button
  • 10k Resistor
  • Jumper Wires
  • Arduino Software
  • Tape
  • Marker

Step 2: Building the Circuit

Connect the resistors to the three buttons and the two LED's with the ground, attach the jumper wires to the LED's and the buttons. Give power and ground to the board. Lastly, make the labels with the tape and the marker to indicate which button is which.

Step 3: Making the Code

Copy the code into the Arduino software.
