/*GraphA simple example of communication from the Arduino board to the computer: Thevalue of analog input 0 is sent out the serial port. We call this "serial"communication because the connection appears to both the Arduino and thecomputer as a serial port, even though it may actually use a...
Press the button. You can now use ‘digitalWrite’ or other other functions to switch on an LED, relay, adjust PWM duty cycle (for example, increase the brightness of a lamp) whenever the button is pressed.A simple way to test this is to use an ‘if’ statement to check the value ...

Two of these are near the relocated reset button and provide additional connections for I2C (the SCL and SDA lines). The other two appeared next to the reset connection on the opposite side of the board. One is designated as IOREF (the nominal I/O voltage, may be either 3.3V or 5V de...
Once everything is ready in your smartphone and the ESP32 is running the BLE server sketch, in the app, tap the scan button to scan for nearby devices. You should find an ESP32 with the name “MyESP32”.Click the “Connect” button....
