Hi guys. I am new to this. My main goal is to attach one or two motors to this rf unit. The purpose is to make a rf controlled snowplow for my RC car.
I have a winch to work the up and down.
I also have a 9v motor which I want to work the left and right motion.
The material I purchased are:
1 x Keyfob RF Remote Control - 315MHz[ID:1095] = $6.95
1 x Simple RF M4 Receiver - 315MHz Momentary Type[ID:1096] = $4.95
I want the a and b buttons to work the up and down of the winch and the C and D to work the left and right motion.
My question is, how do I go about wiring this up? Did I buy the wrong rf board? I think I should have purchased one with 4 relays in order to switch polarities. However, the damage is done, and I wonder if there is a way to wire the 9v motor and winch to this board to work as described above. Any help would be appreciated.

Re: Need help with wiring for RF remote dc motor
this unit will allow you to send control signals to the car but will not have enough power to control the motors directly. You will need to use mosfets or motor controllers to get what you want.

Re: Need help with wiring for RF remote dc motor
The R/c car uses 5 channels already. I have no additional channels to control the plow. MY only option is to make only the plow be RF controlled. The motors are tiny, they are servos motors.
The only thing the rf unit will operate is the up and down motion and the side to side motion of a servo. not the car itself.

Like I said, I am a newb so I had to research for a bit. I finally understand what mosfets do and I thank you for pointing me in the right direction.franklin97355 wrote:this unit will allow you to send control signals to the car but will not have enough power to control the motors directly.

Re: Need help with wiring for RF remote dc motor
I bought the Simple RF M4 Receiver - 315MHz Momentary Type -
ID: 1096 and it lights up the LEDs as advertised as I press down the ABCD on the remote unit.
Now when I feed that logical Hi on the Arduino pins , the system does not work. From a solid lit led I get an oscillation between HI Low, and I can not communicate to the arduino. Therefore the Keyfob system is useless unless I want to see LEDs lit from afar.
What to do? I am using the uno and for the input I use pins 2 3 4 and 5. If I feed those pins from the =5 V on the arduino board, the system works fine.
Thanks

Re: Need help with wiring for RF remote dc motor
Do you have the receiver ground connected to the Arduino ground? You need that for a common signal reference.

Re: Need help with wiring for RF remote dc motor
Yes, arduino and the receiver are fed from the same 5 V Power supply
