Learn more about the ESP32 GPIOs:ESP32 Pinout Reference: Which GPIO pins should you use? ESP32 ADC pins have 12-bit resolution by default. These pins read voltage between 0 and 3.3V and then return a value between 0 and 4095. The resolution can be changed on the code. For example, ...
I have tried it on an ESP32C3-WRoom-02 and also on the ESP32-C3 devmodule 02 with the same result. I simply connected an external power supply to the pins and when connected to GPIO0 it reads the correct value, but on any other pin it only shows an analog value of 700-900 (i...
Grab your ESP32 board pinout and locate the ADC pins. These are highlighted with a red border in the figure below. Learn more about the ESP32 GPIOs:ESP32 Pinout Reference. These analog input pins have 12-bit resolution. This means that when you read an analog input, its range may vary...

max_raw_count- the largest value read. Whilst you might expect it to be 2^10 = 1023 it is often ~ 1020. Note: For ESP32 (with 12bit ADC the value will be nearer 4096) 💡 Find out min and max Every mcu is a bit different and every sensor as well so we advise you to use ...

Using the SS or TRK pin approach is not viable for all buck regulators, as some ICs do not have these pins. Also, with some buck ICs, the SS pin changes the peak inductor current, not the FB reference, so it is necessary to check the data sheet carefully. As an alternative, the ...
One possibility is, of course, toconnect an Arduino to the Raspberry Pi, since it also has analog IO pins and can, therefore, read out those signals without ADC. How this works is described in detail in the linked tutorial. The disadvantage of this, however, is that on the one hand, ...
sensors could be connected to one SPE device creating a pipeline of sensor data as shown in Figure 10. Both publishers and subscribers are MQTT clients that can only communicate with the MQTT broker. MQTT clients can be any device such as Arduino, Raspberry Pi, ESP32, or an application ...
