The main wiring diagram of the project can be downloaded as PDF using the link below:
Description:
- The Raspi communicates via i2c bus with the PCA9685 servo controller.
- The joy stick is connected via serial port with the Raspi.
- On the audio output of the raspi an amplifier needs to be connected.
Hi again, Rolf, i forgot to ask, i do not have a 68R/680 Ohm Resistor, and nor can i find any available for purchase, can i use any of my other resistors, if so what would you recommend, or maybe no resistor? Thanks!
The value of the 68 Ohm resistor is not too critical. It is just some safety not to overload the inputs if they are incorrectly set as output. No resistor would work either, but with a little risk of overcurrent.
