![]() I am checking the Deep Sleep Using Touchpad, But I am facing this issue in Serial Monitor when i touch the pin. I have this, why?Ĭode_moi:40: error: expected primary-expression before ‘}’ tokenĮxpected primary-expression before ‘}’ tokenĬonst int touch2Pin = 5 //add these new lines, choose your own GPIO pins Hello thanks you ! I have an error when I compile. Hay alguna forma de saberlo.Īgradecería que alguien me indicara como salvar este problema. Pensando que se tratara de una tarjeta diferente, he probado distintas tarjetas, con los mismos resultados.Ĭomo puedo saber realmente que placa tengo. Estoy usando WIN10 32Bits y el IDE Arduino.

Touch the aluminum foil and see the LED lighting up.Įstoy siguiendo tus artículos y estoy aprendiendo mucho, cosa que te agradezco. This means that when you place your finger in the aluminium pad, the LED lights up. This code reads the touch value from the pin we’ve defined, and lights up an LED when the value is below the threshold. check if the touchValue is below the threshold read the state of the pushbutton value: variable for storing the touch pin value ![]() Touch the wire connected to GPIO 4 and you’ll see the values decreasing.Ĭopy the following code to your Arduino IDE. You’ll see the new values being displayed every second. In the Arduino IDE window, go to Tools and open the Serial Monitor at a baud rate of 115200. You will touch the metal part of this wire so that it senses the touch. ![]() Testing the sketch exampleĬonnect a jumper wire to GPIO 4. Make sure you have the right board and COM port selected. Now, upload the code to your ESP32 board. You can either pass the touch sensor number (T0) or the GPIO number (4). In this case, the example uses T0, which is the touch sensor 0, in GPIO 4. Use the touchRead() function, and pass as an argument the pin you want to read. In the loop() is where you read the sensor. In this code, in the setup(), you start by initializing the Serial Monitor to display the sensor readings. The T0 pin (touch pin 0), corresponds to GPIO 4, as we’ve seen previously in the pinout. This example reads the touch pin 0 and displays the results in the Serial Monitor. Serial.println(touchRead(4)) // get value of Touch 0 pin = GPIO 4 Just test touch pin - Touch0 is T0 which is on GPIO 4.ĭelay(1000) // give me time to bring up serial monitor In the Arduino IDE, go to File > Examples > ESP32 > Touch and open the TouchRead sketch. Let’s see how that function works by using an example from the library.
