Project 4: Disco Strobe Light
In this project, you’ll apply the skills you learned in Project 3 to make a strobe light with adjustable speed settings.
PARTS REQUIRED
• Arduino board
• Breadboard
• Jumper wires
• 2 blue LEDs
• 2 red LEDs
• 50k-ohm potentiometer
• 4 220-ohm resistors
HOW IT WORKS
Turning the potentiometer up or down changes the speed of the flashing lights, creating a strobe effect. You can use red and blue LEDs for a flashing police light effect (see Figure 4-1). Connect the LEDs of the same color to the same Arduino pin so they’ll ...
