I'm trying to build a Radio controlled TX and RX circuit (using a 2.4 GHz chip and MCUs), to control a robot with four DC geared motors.
I plan to use four momentary on-off-on switches on the TX side to control each corresponding motor on the RX side, but I'm not sure how to accomplish this. From what I understand each momentary on-off-on switch is a "DPDT switch" made from two SPDT switches, so it can control four different circuits. I'm not sure how I should connect them or how this will translate to each channel on the RX end.
What I'm looking to do in simple terms is, when I push a switch up, the corresponding motor will go forward. When I release the switch and it's in its centre open position, the motor will stop. When I push the switch down, the motor go in reverse.
Can you explain to me how I can achieve this?
