The PCA9685 is a quite practical IC. This is connected to the microcontroller (for example ESP8266) via I2C and can then control up to 16 individual PWM channels.<\/p>\n\n\n\n

With just two (I2C) pins on the microcontroller, you can control up to 16 LEDs, servos or, with additional circuitry, motors.<\/p>\n\n\n\n

Especially if you want to control servos, this IC or breakout board makes the work much easier.<\/p>\n\n\n\n

Thanks to ESPEasy and the appropriate plugin, the PCA9685 can be controlled very easily and ultimately controlled via WiFi.<\/p>\n\n\n\n

How you need to connect and configure the PCA9685 to your microcontroller is described in the following article. <\/p>\n\n\n\n

Safety instructions <\/span><\/h2>\r\n

I know the following notes are always kind of annoying and seem unnecessary. Unfortunately, many people who knew "better" have lost eyes, fingers or other things due to carelessness or injured themselves. Data loss is almost negligible in comparison, but even these can be really annoying. Therefore, please take five minutes to read the safety instructions. Because even the coolest project is not worth injury or other trouble.<\/span>
