pic project for beginner?

Hi Jon,

Perhaps for a first project a circuit that would open and close a switch from the signal from a Radio Controlled airplane or car receiver. Basically a device that can turn something on and off via a commercial radio control unit. There are units out there that do this but it sounds like it shouldn't be too hard and is something I could use. Lawrence

What would you like to have after you are done with the project? A useful tool? A toy? Do you want any outcome other than education? What do you want to learn about? What motivates you?

Bike timer might also be a good project!

I don't know much about these receivers (almost nothing, really.) But my vague memory says that they use pulse coding and are usually hooked to a DC servo unit that requires something between say 0.8ms and 2.5ms to indicate a rotation of from 0 to 180 degrees. And I think this needs to be repeated on something like every 20ms, though I don't have any idea what happens if it is repeated on faster cycles (I can guess what happens on slower cycling.) Something like that?

If I got any of that right, then would you like to do something that reads this millisecond duty and then operates a relay switch based on some given time threshold? Like, say, >1.5ms?

U can try Knight Raider Leds

What language are you using? PicBasic, Proton, Assembly, C?

I have had good luck with PicBasic from Melabs. Lots of good stuff including easy LCD interfacing, easy button, serial com etc... I had 2 pics each with LCDs passing messages back and forth in no time. I used ME labs samples for guides and built off of them. The forum offers lots of help too.

I tried assembly but needed to get going quicker and have no prior programming exp...well very little. I suppose I will migrate to C when I don't have so many things to do.
