Hi all! For a college project, I'm trying to make an RC transmitter and receiver for a small model airplane. The general set up is:
Transmitter: Two 2 axis joysticks, Arduino Uno and nRF24L01+PA radio module- Arduino powered by laptop or 9V battery, 10m=uF capacitor across Vcc and ground on RF
Receiver: 3 servos, Arduino Metro Mini, and nRF24L01+PA radio module (plus an ESC, motor, propeller and 7.4V lipo battery)- Arduino powered by laptop (7.4v lipo battery once ready for air), 10 uF capacitor across Vcc and ground on RF
I cannot for the life of me get the transmitter and receiver to communicate together. After troubleshooting this for days, I decided to take a step back and just see if I can get communication between the transceivers with a simpler circuit.
For the "simple circuit": On the transmitter side, I tried transmitting potentiometer values for the receiver's servo to change directions. I've tried this in multiple variations with multiple codes. The transmitter part seemed to /maybe/ work, it's transmitting SOMETHING, but I can't get it to communicate with the receiver.
But I'm running out of time to test simpler circuits before my deadline so I'm mostly looking for help with this specific tutorial for the airplane, as it's closest to what I am trying to achieve (thought there's other similar documentation out there):
I'm fairly confident that my schematics match the transmitter and reciever in the link above. I also don't see how the code would have to change for my setup, so I kept as is. I don't see anything wrong and so I'm guessing one of my parts are bad, the tutorial above is inaccurate, there's a power problem, or I'm misunderstanding how to use RF modules. They do something! Just not what they need tFull code and schematic in link above
Any ideas? I've looked at all the documentation I could, including the "simple nRF24L01+ tutorial" and all the others I could find. I'm getting desperate!
If you don't have any good advice for this topic, I would appreciate other similar project ideas with some of the same parts I have that I could feasibly get done in a week...
Thanks! (happy to send screenshots of anything if that helps)
