Hi thanks for this video it's very helpful can you please explain to me how to connect 2 limit switches because I want to use this to power a wiper motor to move a sliding gate thank you
Hi.I am informing you that without your help it would be difficult to connect the remote to the engine.The package came very quickly but without a scheme.Thank you once again on your video
Hello thanks for the Helpful video, i have one question : is it possible to do a 6 pin as a backup if the remote run out of battery or any other issue ? If yes could you please explain me how. Thanks again
I want to do this setup but instead of using a remote control I want to use a 12volt power trigger. Is there a way to do that with this? Or do I need a different controller?
I wired a manual switch to a linear reversible motor then added this remote but my manual switch burn out immediately. Is there a way to use both ( wireless and manual switch) ? Maybe install diodes?
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. The relays on the board are usually 10 amp max. A circuit diagram would be much appreciated if that was possible. Thanks
I need the same thing but no rf ...I need wifi controller ..for door motor same as yours an 2 direction control....is the same way to connect??can you recommend one with wifi 2 Chanel...thanks..in amazon is possible...
Use different power supply maybe? Like use 6V battery for the motor and 12v battery for the relay module. Otherwise you can opt to use the regulator if you prefer to use a single 12v battery.
@@nudgeme4844 Hi, the regulator have polarity. where should I connect it? i have it drive.google.com/file/d/0B5hwykMylv-XX2NjU0xZRjlybFE/view relay 12 volts and small motor 6 volts
Connect relay module to 12V battery, and small motor to the output of the regulator (replace 9V battery in the circuit diagram with the regulator output). The regulator circuit can be referred here: protosupplies.com/wp-content/uploads/2017/10/LM317-Module-Schematic.jpg
can we use 4 channel relay board on momentary mode to run two motors with reverse control?? Can two relays be turned on at the same time in the monetary mode?? please answer.
Hi, thanks for your interest in my video. For your question, this might be the answer (excerpted from the video description): (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: ruclips.net/video/gnL-5j3eTRU/видео.html, here is the code: goo.gl/dnHLkR. Thank you!
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?
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.
Hii sir... your provided website for circuit diagram of two directional motor control is not working or it shows webpage is not available... plzzz give a circuit dia.
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.
Could you make a code for 8 channel relays to be control with Bluetooth and Arduino, you have helped me in December 2918 with my four wheels drive robot, now I would like to control my robot with relays , thank you once again you are the best Jerry
Please, Do not ignore my question: How to use limit switch, arduino and relay with high current 12V DC motor? I want to use 12v dc wiper motor to power a heavy duty DIY linear actuator. The actuator move forward and reverse and must stop at a precise posistion. I can control the motor manually with 6 pin (forward/reverse/stop) button, but it will not stop in the wanted position. I cannot use limit switches directly to stop the motor because the motor is full loaded and run with more than 10amp to 15amp which will burn the micro limit switches. The question is: I want to use the same thing in this video but with adding limit switches and using simple 6 pin (forward/reverse/stop) button without any remote control, I mean I will click manually on the go left button, the actuator will move left and will stop automaticaly when reaching the left limit switch, I will also click manually on go right button, the actuator will move right and stop when reaching the ight limit switch. I am tottaly a beginner, but I think that the motor will be powered with 12v/20amp power supply, and the limit switches will take current from the arduino so they will not be damaged. (Please correct me if I am wrong). Please, let me knwo if that is possible, if so, how to do it. I will be glad if explain that to me and give a diagram or a video if you please. Thank you very much.
I have dual relay 12v model kr1202-4. And 1 remote. i reset original remote by presing a+b buttons and my remote not work anymore, please help me?! What should I do....
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?
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.
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.
