PT100 directly, as I thought, the ADC can do the job.
In all samples I've seen, they use a voltage divider, which is as far as I know, not needed here. Or, can someone explain me, why I need this?
I have a reference voltage of the ADC and a resistor.

ADS1115 and PT100 - EL skills needed
Hello community You may know BBQ. You also may know the company Weber. They build Grills for way to much money. So far, so well known. I recently reverse engineered the Weber iGrill 3, which is in fact a pretty stupid Bluetooth thermometer with >>10m range for ~180€. So far, so well known. Now, I wa...

PCA9685 and positive PWM
Hi there First, thanks for that cool infrastructure Project! I have at the moment several devices running ESPeasy. Unfortunately I'm struggling with one of them. My problem is, that I can't drive a NPN transistor thru the PWM channel with the PCA9685. If I use a LED, it works like in the datasheet, ...
