@zander I went with the 150W power supply because the manufacturer, as well as reviews, recommended 100W for one roll. I am extending it beyond one...

@farzad_k That makes sense and sounds easy enough. I will make a suggestion that you should feel free to ignore if you wish. DHT sensors are not ...

@jbo I had the same issue, and still do I guess. My solution was to not go over the point in the breadboard that the two smaller breadboards connect...

I have used the DHT22 and the other variants on an ESP32. It was exactly the same as any other arduino. There is a library for DHT sensors that is for...

@voltage @will Sorry I'm late to the party. Woke up to having to put out the proverbial fire. It sounds like you are setting the ramp up spee...

@Voltgae and @will I want to make sure we don't get too far ahead of ourselves. So for clarification: Do you need the same arrangement for buttons...

@will So you are saying that 1 button be a stop/go function and the other be direction and not accessible in go? That sounds good but that still lea...

It would work but how does he stop it? I think I did it that way so that it would be a stop function and when it was not in use be a reverse direction...

That would mean there would be no stop button, only a reverse direction button. I think that might have been a test where I realized there are o...

Only use the buttons on the shield and no pot. I posted an updated version of the code above. If it works it will give you a definitive and stab...

Sorry, I stayed up really late last night reading contracts and riders. Then making list of all the things to do and look for. Plus, I am on the west ...

@voltage @will Ok, I have a test. I want to see how bad of a delay there is using the buttons on the shield. It will also let us know how some of th...

@voltage @will That jitter in the pot was why I suggested an encoder before. Store the value as an int and adjust it up and down. If you want to exp...

Ok, to be honest, do you really need RPM? I would say display the mapped number from the pot. Then do the math to what diameter that would be right fo...

I have to go tour a construction site. I will be back later to catch up. Feel free to mess around with the code all you want.
