The IS31FL3197 4-channel LED driver is very functionality controller of RGBW LEDs. Its detail description see in the datasheet of it. But it’s futile idea to seek for initialization procedure example there. In order to initialize the IS31FL3197 LED driver you need to do next sequence of steps described following.
To connect the HC-SR04 ultrasonic ranging module to microcontroller (for example, Arduino UNO), four wires are usually required. But while the Vcc and GND wires are necessary, the Trig and Echo wires can be “combined” into one with a simple circuit. The software to control the HC-SR04 ultrasonic ranging module via one signal line see […]
