Connecting the positive pin on the callipers to the 3.3V supply means when the clock and data pins are connected to the arduino their voltage seems to vary between 3.3V and 1.8V, which is the Arduino reads as logic high and low respectively. Powering the callipers with the Arduino: To avo...
We then noticed that this issue with the temperature reading only happens when the AC motor is running, so we are thinking maybe it's the noise from the motor? Here is the voltage from the RTD to the ground while the motor is running ...
Hello, I would like to ask you for help with ESP32-C3 built in ADC. I tested multiple channels on ADC1 and still reading 4095 at 2.8V Regarding datasheet effective range for 11db attenuation (ATTEN3, which should be default) is 0-2500mv and reference voltage is somewhere between 1000-...
