RF communication is essential for any type of RC controller. In this project, I've tried to find the best way to send information through a wireless RF Link. I'm willing to receive feedback about my results. I did the project just for fun; however decided to publish it so that other people can see how I did it.
Today I've tried to do the same thing but using 3 potentiometer; it seems to work but the receiver it's not refreshing so the leg RGB doesn't change :( However, it's interesting that when the receiver arduino begins or when restarted, it refreshes. Another thing is that if the antennas are touching each other it works. I think it is not a problem of the transmitter because it works from more than 5 meters away when the receiver is restarted. I might have forgotten something on the receiver code or even i don't know. I'll look for another methods.
What I did today is to see how a code and hardware behaves. It is pretty much decent and works at distances up to 10 meter (with antenna in both circuits). Still not sure if it is the best way to send data.
Aside the arduinos and the transmitter/receiver link I've used 4 leds, 3 buttons and one potentiometer. The 3 buttons send a signal to turn on a led respectively, while the potentiometer sends an analog signal to light up or down the left led.
