IR Remote Control Kit (HCKITS0006)

[andrew]

Hi Chris, Thanks for pointing this out. We used to ship it with a 21 button remote but that was a long time ago. I’ve had a look at the listing and everything looks ok apart from the bit in the description where it says 21 buttons?

I’ll get the description updated and double check the stock to make sure it is as per picture and sketch.

hi i bought one of these kit from amazon and being a complete novice i had to get some help via freelancer to do the coding of this to an Arduino uno r3 they agent told me that there was a problem with the remote and or sensor, i purchased another and have plugged it in exactly the same, is there anyone who can help me determine if it is working, on the original when i press a button on the remote the light flickers on the receiver, however on the replacement when i push the button nothing happens with the light so i am not sure if it is working or not and there is no user manual to tell me what the standard operation should be
following on from this i have tried isolating components, with the ir sensor only connected light stays off and flashes when button pushed, with limiter switches connected the ir sensors acts the same. however when i connect and switch on my stepper motors the light on the sensor stays on even if disconnect the leads running to the Arduino board the ir light stays on i cant understand why this would be any help would be welcome

For the ones we sell, the LED is driven by the IR receiver and illuminates whenever it is receiving an IR signal from the remote control. It could be that the second module has a different functionality if it wasn't purchased from the same seller but it could of course be a problem with the module or remote.

Have you tried using the remote from the first module (which is known to be working) with the second receiver?

Do you have the ability to upload a library and sketch to your Arduino and test the module in isolation yourself? If you you may want to try the example sketch and library from the first post of this thread:

Again, just for caution, the example in the first post was written for the modules/remote we sell. So if you didn't purchase yours from us please check that the module is of the same type and same pinouts.

thank you for coming back to me we have tested the ir with nothing connected and the signal is received as soon as i switch the motors (nem23 stepper motors running with tb6600 4.5a stepper driver) the ir sensor light comes on permanently and does not receive a signal cant understand why

Hi John, if I understand the above correctly, you are saying the module works fine until you run the motors?

If so then it would suggest to me that it could be a power supply or noise issue. I assume you don’t have access to an oscilloscope to check the condition of the 5V supply to the module?

Failing that, if you have a multimeter, you may want to try disconnecting the module’s signal pin from the Arduino, but keep the GND & 5V connected. If the LED comes on that would also suggest a supply/noise issue.

If it doesn’t then, with the module's signal still disconnected, try measuring the voltage at the Arduino pin. If it goes high when the motors are run it would suggest the software may be trying to drive the signal pin high.

You did understand it correctly, I have tested the ir sensor on its own nothing else connected I slowly started connecting the the components 1 by 1 with limiters no problems with 24v power supply (for stepper motors) not connected to motors no problem, then I connected the drivers not connected to the motors no problem. However when the motors were wired in the led would light up and not go off, I also noted that the tx light came on on the arduino. Not 100% what to try next I have some different stepper motor drivers I can try alternatively I might need to look at a different receiver and remote can you recommend any alternative options you have available

However when the motors were wired in the led would light up and not go off,

That would point more towards a power supply issue (brown out or noise) or RF noise.

If you have any capacitors to hand you could try putting one locally across the modules power pins to see if that helps. I would suggest something in the range of 10uF to 100uF and also an additional 100nF. The two would help with dips/brown outs in the supply and any high frequency noise.

I also noted that the tx light came on on the arduino.

I’m not sure what that would suggest but the first thing I would check is if the Arduino was actually transmitting something out of the serial interface. With your Arduino plugged into your computer, open the terminal in your Arduino IDE and see if it's doing anything.

I might need to look at a different receiver and remote can you recommend any alternative options you have available

The only other IR receiver we stock is our own mLink IR transceiver module:

Note though it is only compatible with remotes that use the NEC protocol (the most common type) and of course you’d need to modify your code to work with it instead. An example can be found in the first post of this thread:
