Connecting A Iotiny/PCA9685 Together?

Skip to comments   Jump To End

Was wondering if anyone has connected a PCA9685 to a ioTiny?

I am building a robot head for my grandson. Have a extra ioTiny and PCA9685 lying around here and would like to use them. The head has 13 servos, the ioTiny 8 ports, not going to workie! Was hoping I could connect them together for enough ports!

I don't want to spend too much on this as I don't know if this is going to be something he uses or puts away in a drawer. If you know what I mean?

Thanks ... HerBall

ioTiny has i2C so there should be no problem.
