“HW-687 is one easy module for adding speed regulation to your next DC motor-based project. It is a simple pulse-width–modulated speed controller providing smooth control with almost no jerks. There ...
Charlieplexing is a technique of controlling many LEDs using a few I/O pins. Charlieplexing is same as multiplexing, but it uses the tri-state logic (high, low input) to reduce the number of pins ...
The 16-channel 12-bit PWM/Servo Driver, PCA9685, is an ideal module for precise control of multiple PWM outputs that are commonly used to control servos, LEDs, and other devices in applications such ...
