Measuring current on all the phases of the Z stepper motor and try to determine if there an over current condition may get complicated. As I'm sure yo...

Sorry no one replied to your question. If your still looking into this I would suggest looking into the details of the working of the library RadioHea...

Depending on how your code works you may want to also check the timers the libraries you are using. I know some of the radio libraries reserve timers ...

Thanks guys, I've been looking for a project for TTGO esp32 and it would be nice to have a portable inductance meter to sort all the miscellaneous i...

@roborobs Unfortunately, it got lost in the mail and I got a refund. It took so long to get it resolved that I 3D printed a front plate that fit the p...

Conceptually, there are a number of ways this can be implemented. There are vast amounts of information on the wed as to how to make lights flash to s...

This idea is a little different and may not be right for what you want, but here goes. You could affix the IR sensor to pick up the teeth on the front...

I've had good luck so far with the BME 280 pressure, temperature and humidity sensor. It still uses I2C but I found that is a good thing as you can qu...

I'm sure there are a number of people on the site who have experience with speed controllers depending on the application. Can you provide more detail...

@byron I think the video you referenced is very appropriate example for monitoring the 9V supply the OP asked about. The video was covering how to m...

I believe it would require making connection directly to the battery holder on your RTC and monitoring it with an analog input. I would caution you on...

An easy way might be to use a speed sensor (this can be optical or magnetic) on the motor as feedback. Some motors can be purchased with them already ...

@jonaskell Grabbing at straws here but you don't have much of a delay in your loop and the Serial.print may be walking on each other. take a look at

@mubasher Here is the link... Hope it helps.

@amin I'd be surprised if such a library exist. There would be no way for a library function to get back control once it relinquished it. However, i...
