Touch Sensor Switch and Stepper Motor

[mikeH76]

Firstly, let me say, thank you for Winderoo. I have recently completed my build and its fantastic.
Thank you @mwood77 , its working fantastic.

I know there is a thread about the stepper motor option and I am going to look into that as I must say, the standard motor is a bit too noisy. Ive adjusted the motorSpeed in MotorControl.cpp to 85. I tried some lower values but then it wouldnt rotate. At 85, it still is too noisy IMO.

Id like to raise the question of how to implement a touch sensor for on/off functionality. Ive purchased a sensor on AliExpress, thats a four wire sensor. Im a little unsure of how to implement this into the winderoo wiring schematics.

If anyone has any experience with this, please let me know.

Regards
Mike

Hi @mikeH76

I can't help much as I've never used this sensor - or any touch sensor. It's a bit strange that it does not have a signal wire, so perhaps that's carried on the VCC/GND wires. I assume one set is for the sensor, and the other is for the LED.

Regarding the noise, yes the motor can be a bit noisy due to the planetary gear-set. However, if you add isolating (rubber) feet that'll significantly reduce the noise level.

Thanks for the suggestion regarding the rubber feet. I'll definitely give that a try. I'm going to have a play with that touch sensor on the breadboard and see what I can do to integrate it into the circuit. I suspect the led wire just creates a open or closed circuit and the VCC nad GND is to power whatever lives inside the sensor.

Attached is my latest view of my watch winder. Made a makeshift mount for the LCD screen until I can integrate it into the base stand later on.
