3DX Potentiometer and LED Project
thingiverse
LED light bar graph indicator with a precision control feature is achieved by integrating a potentiometer to sequence the LED lights. This DIY project utilizes an Arduino board, a breadboard for circuit arrangement, and a 3D printed bracket to securely hold the LEDs and potentiometer in place. The necessary components include jumper wires, 220 ohm resistors, 5mm LEDs, and a potentiometer for adjusting brightness levels. Additionally, the project requires a 3D printed knob cover to protect the potentiometer from dust and wear.
