Rotate the potentiometer and see the values changing.AD FS requires a full writable Domain Controller to function as opposed to a Read-Only Domain Controller.

Testing the ExampleĪfter uploading the code and pressing the ESP32 reset button, open the Serial Monitor at a baud rate of 115200. Make sure you have the right board and COM port selected in the Tools menu.
potValue = analogRead(potPin) įinally, print the values read from the potentiometer in the serial monitor. In the loop(), use the analogRead()function to read the analog input from the potPin. In the setup(), initialize a serial communication at a baud rate of 115200. In the code, you start by defining the GPIO the potentiometer is connected to. This code simply reads the values from the potentiometer and prints those values in the Serial Monitor. variable for storing the potentiometer value Potentiometer is connected to GPIO 34 (Analog ADC1_CH6) Open your Arduino IDE and copy the following code.

Windows instructions – ESP32 Board in Arduino IDE.We’ll program the ESP32 using Arduino IDE, so make sure you have the ESP32 add-on installed before proceeding: You can use the following schematic diagram as a reference. The potentiometer middle pin should be connected to GPIO 34. You can use the preceding links or go directly to /tools to find all the parts for your projects at the best price! ESP32 DOIT DEVKIT V1 Board (read Best ESP32 development boards).To see how everything ties together, we’ll make a simple example to read an analog value from a potentiometer.įor this example, you need the following parts: Read Analog Values from a Potentiometer with ESP32 There is a very good video explaining these functions that you can watch here. Get the result of the conversion: returns 16-bit integer. Check if conversion on the pin’s ADC bus is currently running (returns TRUE or FALSE). adcStart(pin), adcBusy(pin) and resultadcEnd(pin): starts an ADC convertion on attached pin’s bus.adcAttachPin(pin): Attach a pin to ADC (also clears any other analog mode that could be on).Attenuation values are the same from previous function. analogSetPinAttenuation(pin, attenuation): sets the input attenuation for the specified pin.ADC_11db: The input voltage of ADC will be attenuated, extending the range of measurement to up to approx.ADC_6db: The input voltage of ADC will be attenuated, extending the range of measurement to up to approx.ADC_2_5db: The input voltage of ADC will be attenuated, extending the range of measurement to up to approx.ADC can measure up to approximately 800 mV (1V input = ADC reading of 1088). analogSetAttenuation(attenuation): sets the input attenuation for all ADC pins.analogSetClockDiv(attenuation): set the divider for the ADC clock.It has an effect of increasing sensitivity. analogSetSamples(samples): set the number of samples in the range.analogSetCycles(cycles): set the number of cycles per sample.It can be a value between 9 (0 – 511) and 12 bits (0 – 4095). analogSetWidth(width): set the sample bits and resolution.analogReadResolution(resolution): set the sample bits and resolution.There are other more advanced functions to use with the ADC pins that can be useful in other projects. So, if you’re using Wi-Fi and you’re having trouble getting the value from an ADC2 GPIO, you may consider using an ADC1 GPIO instead, that should solve your problem. Note: ADC2 pins cannot be used when Wi-Fi is used. This means that when you read an analog input, its range may vary from 0 to 4095. These analog input pins have 12-bit resolution.
