Here’s a simple test program to check that your PCA9685 and servos are working properly. This code uses the Adafruit PWM Servo Driver library, which makes controlling the PCA9685 very easy.

Maker Michael Klements has built a unique electromechanical clock using a little Arduino hardware, code, and 28 servos, which tilt panels to reveal the correct time in digital format. As the time ...

I was looking at the electronics behind the little Petoi dog robot (right), and noticed a chip I was not aware of before, NXP’s PCA9685. On a deeper delve, I noticed Adafruit also uses it for creating ...

One I missed: led driver repurposed for 16 servos I was looking at the electronics behind the little Petoi dog robot (right), and noticed a chip I was not aware of before, NXP’s PCA9685. On a deeper ...
