2-CH RF Wireless RC Relay Module: DC Motor Forward/Reverse Direction Control

This video demonstrates the simple way to control the direction of a DC motor which in this case a 12V car power window. Two relays were used to build the required circuit and in this video, a 2-channel RF wireless remote control relay module was the perfect choice to do that. The connection is so simple; everybody with or without basic electronic knowledge can build the circuit in minutes and use it right away. This video intends to give some basic idea on building a bidirectional motor control circuit and you can apply it in your own project/application.
For those who are having trouble catching up the connection for 2-direction motor control in the video, you may refer to this diagram: goo.gl/Fnsf4B. Just ignore the Arduino side as the relays themselves will be activated through button click. However, if you in case to build Arduino controlled 2-direction motor control, then this may be the diagram you are looking for.
The Arduino code to make the motor run forward and backward continuously with 2 seconds of duty cycle: goo.gl/iN7sfr.
Circuit diagram: goo.gl/rxqDrg.
Demonstration video: • DC Motor Forward/Rever... .
The Arduino code to make the motor interact with input from serial communication: goo.gl/ZqecCP.
Circuit diagram: goo.gl/u5AQKg.
(Updated on 26 Feb 2019): For 8 channel relay module: goo.gl/admrPB (pin connections are described in the code introduction).
(New - Updated on 29 November 2017) The Arduino code to make the motor interact with input from serial communication + manual push buttons: goo.gl/iPjDhZ, with help of circuit diagram: goo.gl/fLeJpF.
For those who don't want Arduino in the diagram, refer this circuit: goo.gl/kjjoKU, with truth table included.
(Updated on 1 March 2018) For those who are interested to use limit switch in the circuit (such as for linear actuator motor control), refer this circuit: goo.gl/C5ATjB for LOCAL controlled single limit switch version and this circuit: goo.gl/83mynM for LOCAL controlled double limit switch version. And for REMOTE controlled double limit switch version, see here: goo.gl/gZVRp2. Hope that helps :)
(Updated on 29 November 2018): If you want to make the motor turns forward until a limit switch is pressed, then wait for let say 1 hour before going reverse until another limit switch is found, then wait 1 hour again and repeat the process again like more or less shown in this video: • Forward/Reverse Direct... , here is the code: goo.gl/dnHLkR.

[@andreamitchell4758]

but why would you use an RF relay board if you want to control it with an arduino? how would you even control this RF board with an arduino, wouldn't you need to use another type ot board with wired controls and not RF remote for arduino?

[@nudgeme4844]

You're right. However, if the users insist to activate the relays using Arduino, they may use the relay module instead of the RF relay board. This tutorial demonstrates not only how to operate the RF relay board, but how to do motor direction control using relays as well.

Hello thank you for your video, was very informative. I have a question, what if I would like to put a timer to control the motor, 5 PM open, 7PM close?

[@nudgeme4844]

Hi, sorry for late response. To do that, you probably can use either one these options:First, use an Arduino to act as a timer. The RF relay could be replaced with a 2-ch relay module, which can be connected directly to the Arduino through jumper cables. Programming wise, you may have to use simple delay function or RTC module to implement the precise timing routine.Second, use ready made programmable timer as shown here: www.timer-switch.com/time-switch-timer-switch or here: www.amazon.com/2013newestseller-Multifunction-Self-lock-Module-Automation/dp/B00J0SMB3C. Please note that these kind of modules do not need any programming job as they are configurable through their buttons. The timer module then needs to be connected to the relay to do the reverse/forward motor control per needed.Hope this helps. Thank you.

Hi Nudge Me, Thank you so much for the video and circuit diagrams. I'm having trouble figuring out how to use a remote controlled double limit switch to run a higher amp motor like 30 amp.

Hi all. Please help me I don't know what to do. There is such an assembly through a 4-channel relay and through the switch pedals to the motors. The remote control works great. The pedal in one direction also works fine. And the Problem is that when you press the pedal so that the motor spins in the opposite direction (reverse), there is a short circuit in the relay area and even one relay has already burned out. As an option, I thought to put a switch between the relay and the pedals, that is, either turn the motor through the pedals, or through the remote control, but I would like it without a switch, that is, when I wanted to press the bullet or the pedal. Please help me how to fix this.

Yes, the motor will still run even without the Arduino as the RF relay module itself activates the respective relay when button A or B is pressed, definitely the Arduino is not needed here.

[@msacco]

@@nudgeme4844 Thank you! awesome video!

[@nudgeme4844]

You are welcome!

[@jbh.6257]

is there a way to add in limit switches on each direction of rotation? For example you press "A" and the motor runs CW until a limit switch is hit the system shuts off ("A" and CW is dead) then only "B" can be pressed which runs the motor CWW until a limit switch is pressed killing that direction and thus pressing "A" starts the cycle over again. Basically opening and closing a door on a gear track.
