    CircuitPython 5.0.0 Alpha 4 released!

    CircuitPython is a programming language designed to simplify experimenting and learning to code on low-cost microcontroller boards. It makes getting started easier than ever with no upfront desktop downloads needed. Once you get your board set up, open any text editor, and get started editing code. It's that simple.

    @salmanfaris best if you could point me to an example that works as described: getting different values depending on hoe close the finger is without really touching. nothing i tried did work yet

    @salmanfaris I haven't found a good sensor module for this at all. I used a thing which was calles touch sensor and it returns only 1/0. Tried to use touchRead() but it is not sensitive apparently, only 40 and 1 more or less.

    #define touch_pin_numer 33

    const int VALUE_THRESHOLD = 30;
    int TOUCH_SENSOR_VALUE;
    void setup()
    {
    Serial.begin(115200);
    delay(1000);

    }
    void loop(){
    TOUCH_SENSOR_VALUE = touchRead(touch_pin_numer);
    Serial.println(TOUCH_SENSOR_VALUE);
    if(TOUCH_SENSOR_VALUE < VALUE_THRESHOLD)
    {
    Serial.println ("Touch ON");
    }
    else{
    Serial.println ("Touch OFF");
    }
    }

    should show something between 40 (current max) and 1 (current min) the closer the finger gets but it shows 40/41/39 and 1 - nothing inbetween. got this code from the web

  • @FlorianB Can you share the code, output window/error and details of the sensor module?

    Hi! I am trying to add an capacitive sensor to the ESP32, that will work through glass with 3mm thickness and an distance of 8 to 2 cm. I have bought sensors which only work on touch, i have looked into the touchRead() function but cant get a steady value increase/decrease with distance and only a real touch gets me enough difference to count it as a "touch". I have checked Arduino examples with foil where a resistor can set the sensitivity but nothing worked on my ESP32. i have spent hours looking for an example, can somebody point me to one please?
