Ok guys I am not very experienced with this so bare with me. I have a project I have been brainstorming about for a few days now. I have researched it and learned as much as I understand and now I am hoping to get some input form you guys. Here is the plan
I want to wirelessly control a pot from about 15 feet away and also a single contact used as well. The unit im working with gets controlled by a foot pedal.. Inside the foot pedal there is a 1k 1t 2 watt pot and a contact switch that turns the circuit on. I can relocate the pot and switch to a box mounted to the unit and I want to control it from 15 feet away. Now can I use a new pot mounted in the existing pedal and run it to a controller and send the signal to the box housing the original pot and control that with a 360 degree servo and a belt and pully? and also have it activate the switch in the box. How would I achieve this? What would I need to purchase and how hard would it be to program? Its for a friends school project so I dont want to spend a fortune doing it either. Thanks guys
ok One more thing to add. There is another device which uses different frequencies close by. So interference may be a problem, Im not sure if it will so I will have to try it out and see . Any way to do it infrared? Would it have to be in a direct line of sight?
Yes I do know what the pedal is supposed to do. It sends a zero to five volts out. It has to be wireless. Thats the whole reason for the project. I dont know what the frequency of the other nearby device is or how it will or wont interfere. I have not looked at what this is doing in person yet. Im just going by what I was asked. Its some secret school project for my cousin. He hasnt told me everything yet. I am a hydraulic system engineer and he came to me thinking I could figure it out but I dont design any of our control systems so this is outside of my knowledge.
Got to walmart and check out the el cheapo RC toys. Probably can get all you need there for less than $20.
