Hello I’m new to Arduino and I given project by my lecture to monitor voltage, current, and power using INA219 sensor with ESP32 to transfer the data to blynk and monitor it through smartphone. Can anyone help me? Reply MSiska 3 years ago Just discovered this site… Awesome and cl...
Following is a pin mapping of with ESP32 devkit DOIT board. Although ESP32 chip ADC1 has eight channels, the Devkit DOIT board supports only 6 channels. But still, we have enough analog channels for analog sensor interfacing. ADC1_CH0 >>>GPIO36 ADC1_CH1 >>>Not available on this board...
Yes, I am having the same issue. I have configure the ADC1_CH6 as 12 bit adc, Vref = 1.1V and attenuation = 11Db. The ADC pin is reading the op-amp circuit output. and circuit is connected with the FSR sensor. Here, I have attached the picture of the Op-Amp circuit. Where FS...

47K POT with a 10V Input as a voltage divider outputs 0 - 10V depending on the potentiometer position. How can I do this using the ESP 32? ESP32 output 0 - 3.3V depending on the magnet position to the hall sensor. Use that output of 0 - 3.3V to control a digital pot? (like ho...

We’re always excited when a message from [Aaron] hits the inbox, since more often that not it means another device has received an open source firmware replacement.From his earlier work with cheap fitness trackersto hiswildly successful Bluetooth environmental sensor hacking, we don’t think thi...
The device consists of a precise, low-offset, linear Hall sensor circuit with a copper conduction path located near thesurface of the die. Applied current flowing through this copper conduction path generates a magnetic field which is sensed by the integrated Hall IC...
