In this post we will see how to make a Larson Scanner. This is best known from the famous Knight Rider Car KITT from 80’s.

This effect is made using many kinds of circuits to drive some LEDs to give the desired visual effect.

Today we are going to use Arduino UNO to make this visual effect of Larson Scanner.

Tinkercad Simulation of Larson Scanner from Knight Rider

We start with the example from Arduino website.

This example from https://www.arduino.cc/en/Tutorial/KnightRider

Here we assemble the circuit on Tinkercad

Knight Rider Circuit on Tinkercad

You can use the simulator on Tinkercad or you can assemble the real circuit.

Components:

Arduino UNO

6 RED LEDs

Some wires

Breadboard

You start by connecting the LEDs on the breadboard to Arduino Pins from PIN 2 to PIN 7.

You can upload the code from Arduino Website to the Arduino UNO board. Then start the application.
