I'm interested in using an Arduino Nano to decipher a 2.4Ghz radio remote receiver signal and transform it into a hall effect sensor signal output to a DC motor controller for remote motor speed control. No brakes, steering, motor direction or any other controls, just to turn PPM signal from rc remote receiver into hall effect PWM signal for motor speed control only. What pins on the nano do I connect the rc receiver to? What pins do I connect from the output of the Nano to the motor controller (+5v, sensor, Gnd)? Which code should I use to program the Nano? I also understand there are I believe two resistors I am also supposed to connect to the circuit (10K & 100K) I believe the 10K resistor goes between the Gnd and the +5v pins of the Nano output but I am unclear where the 100K resistor goes.
Currently, I have 36vbdc motor powered with a 36v li-ion battery and controlled with a brushed DC motor controller which uses the output of a corded hall effect sensor for the throttle. I am trying to replace the corded hall effect throttle with a 2.4Ghz radio remote using the Nano to decipher the signal and transmit it to the motor controller. I have included pics of the electronics.
Any help would be greatly appreciated. Thank you.
Read 32 times and not a single answer huh? And here I was told, "There are many knowledgeable, helpful people there on Arduino forum and surely somebody there will know how to do this and give you some help". Guess not. Guess I'll have to try somewhere else. Thanks anyway.
Lots of help here, but what have YOU tried and how did it work or not work? We don't supply kits.

If you had posted datasheets/specifications of your components instead of useless photos it would have been easier to help. What do you think the chances are that anyone here doesn't know what a Nano looks like?
Good luck finding help - Steve

I've read it multiple times, just to make the statistics look better.

No attitude. In an Arduino forum? I thought the odds of finding people who are familiar with the Nano were pretty good, my bad. I don't know what other info to post, I'm totally new at this. This was the board I was told to get to interact with the components I have (to decode signal from RC receiver and output analog 0-5v signal to replace hall sensor throttle), was just wanting some directions on how to wire it, I think it's also supposed to have a low pass filter. Didn't think what I was asking would be that difficult. My bad again I guess. I have not tried anything yet because I can't find any wiring instructions for it. I certainly wasn't intending to piss anybody off. Seems I keep running into people who would rather be pissed off and lash out than to do anything else though. I apologize if I didn't include enough info as I don't know what else to include, or if I didn't use the right vocabulary or if I wasn't clear enough. Really it shouldn't matter what motor controller or 2.4Ghz transmitter and receiver I'm using, how to wire the Nano to decode the digital 2.4Ghz receiver signal and output 0-5v analog signal to replace a hall sensor throttle (+5v, sensor, Gnd) should remain the same.
O.k. You can connect the receiver channel outputs to any of digital pins on the Nano you feel like.
But the Nano does not have a DAC so there is no practical way that you can get 0-5V analog signals out of it. If your motor controller really needs signals like that then you're in trouble. Many motor controllers have alternative inputs but since you don't want to give any details of what controller you're using I can't help you there.
