Trying to complete this project but can't solve a problem. Using a Bescor-MP101 ptz controllerhttp://www.21best.com/21_best/electronic/security/video/pan_tilt/MP-101b-pan-tilt.html, RadioLink RC remote and receiver and Arduino Nano to pan and tilt my Canon Camcorder.
Using Yvan / Wireless Arduino controlled PTZ Camera System (brainy-bits.com) project and code. Could not get the RC remote he used but thought this Radiolink should be the same. But can't get it to use both pan and tilt channels together. Can only use one or the other. If I remove the pan connector from pin D2 on the nano it will tilt. Or if i remove the tilt connector on pin D3 it will pan. But if both connectors are connected it will only tilt does not pan. This project will also zoom but haven't got that far.
I'm new at all this, never used any of these parts before. Electronically and computer literate Just trying to build a pan/tilt remote system for our camera.
Using a breadboard to make all the connections.
Power is coming from the Bescor-mp101 using extension cable cut the female connector off soldered breadboard wires onto each wire.
6.2v pin 4 purple wire to nano 5v pin
Then the following wires, verified all wires are correct to proper pins on Bescor mp-101
Left pan pin 2 yellow wire to nano D11 pin
Right pan pin 6 white wire to nano D10 pin
Down tilt pin 3 blue wire to nano D12 pin
Up tilt pin 5 black wire to nano D9 pin
Ground pin 1 red wire to nano GND pin
RC receiver is powered using breadboard 5v pin
Checked the receiver using the Radiolink app and the channels are being outputted correctly.
CH 1 is connected to nano pin D2 (right joystick Left/Right) Pan
Ch 3 is connected to nano pin D3 (right joystick Up/down) Tilt
Here is the code I'm working with below
