Hello i've made a robot, but I need some help finding compatible parts. I need a rc transmitter and receiver. There needs to be a minimum of 5 channels no less, and also make sure they're compatible.
Hobby king has good prices on RC equipment.
If you use a pair of nRF24L01+ 2.4GHz transceivers you could have a dozen or more “channels”.
I don’t really mean channels, but different data items for different actions by the “receiver”. Sending data is much more efficient (and simple) than trying to decode pulse widths from standard R/C equipment.
I am using this type of system for radio control for model trains.
It can also send data in both directions.
