This circuit is used to control 8 servos directly from our PC.
The circuit is based on the PIC16F84, some of us have also tested with the PIC16F84A.The integrated simply communicates with the RS232 port of which we use only two of nine-pin disposizioni.Rispettivamente PIN3 which is a RX or is the PIN from which we receive the signal from the PC and the PIN5 that is the mass.The circuit and its operation is quite simple.Below we leave you to the video that shows him in action, some of his photos and finally a link to a site where you can find everything you need to be able to realize.
