  • How to build 433 MHZ RC to control servos (100% Arduino)

    The reason he is using two Arduino's, is that the two libraries needed, Servo.h and the VirtualWire [VirtualWire.h] or RadioHead [RH_ASK.h] both try and use interrupts with timer 1 and have a conflict.Having two separate boards do this is handles down the cheapest, easiest, and fastest solution for someone getting into Arduino.Fixing this would require allot more work then most Arduino beginners and intermediates are comfortable or able to do.I spent hours trying to find a work around that worked with my application, and got no where. The easiest way to do it that I can see to not have to use two Arduino's, would be to not use the VIrtualWire.h Library at all. This would require you to code your own communication protocol between the transmitter and receiver for synchronizing, and sendi...see more »The reason he is using two Arduino's, is that the two libraries needed, Servo.h and the VirtualWire [VirtualWire.h] or RadioHead [RH_ASK.h] both try and use interrupts with timer 1 and have a conflict.Having two separate boards do this is handles down the cheapest, easiest, and fastest solution for someone getting into Arduino.Fixing this would require allot more work then most Arduino beginners and intermediates are comfortable or able to do.I spent hours trying to find a work around that worked with my application, and got no where. The easiest way to do it that I can see to not have to use two Arduino's, would be to not use the VIrtualWire.h Library at all. This would require you to code your own communication protocol between the transmitter and receiver for synchronizing, and sending information, although if you youtube searh a bit on the wireless module, you can find some folks who do that, and you could follow in their footsteps and modify things for your code.BUT, with how cheap you can get a clone, getting a nano or something for the other board, is cheap, easy, and for a beginner will save you allot of headache
