Sean Pullinger 0 Report post Posted July 17, 2017 The connection J1 (RC In) Pin 7 of the PIC12F509 is used for the input of the R/C RX CHNL. Is there perhaps an alternative method of rather using a variable resistor (POT) to connect to Pin 7, VCC and GND? Joy sticks are usually available with a 10k or 20k variable resistor. I will not need a R/C since I will be using this Pan Cam Project for a JIB Arm (Camera Crane) to control the Pan and Tilt operation and the distance is only 4 meters. Any advice will be highly appreciated. Share this post Link to post Share on other sites
Mr.RC-Cam 121 Report post Posted July 18, 2017 Direct connection to a POT is not supported. A servo tester can be used instead of a R/C system. Share this post Link to post Share on other sites
Sean Pullinger 0 Report post Posted July 19, 2017 Thanks so much. I do have a 555 servo circuit that uses a POT. I will give you feedback once I have constructed and tested the circuit with your Pan-Cam circuit design. Share this post Link to post Share on other sites
Mr.RC-Cam 121 Report post Posted July 19, 2017 I think that some 555 timer based servo signal emulators have unusual repetition rates that could affect PanCam's operation. For correct operation the servo pulse signal should be a standard 50Hz repetition rate (20mS period). Share this post Link to post Share on other sites
