Single Joint Gear Potentiometer Sensor Module for Arduino - Blue
This is a single-gear potentiometer breakout board module£¬ and the potentiometer resistance is 50k. It can be used to adjust the volume£¬ motor speed£¬ the brightness of the lamp. SIG pin of the module outputs an analog value so MCU can do the appropriate operation by reading it. Features: - Working voltage: 3~12V DC - Working Current: 0.24mA - Great for Arduino DIY projects
