The Button will send “F” letter to HM-10 which will turn off the LED connected to Arduino. Now you can see the two buttons created just below the Text Field. Now if you want to control LED then just ...

The circuit is simple. Point the “-” pin on the RGB LED module to the Arduino’s GND pin. If you align it right, the other three pins should enter pins 13, 12, and 11. Making It Work. Once you’ve ...

The code makes the LED turn on and print “LED on” on the Serial Monitor for 0.5 seconds, then does the opposite, turning the LED off and printing “LED off” for the same amount of time. To save, click ...

In this project, an external LED is connected to the Arduino Uno, and the LED's state (on/off) is controlled via digital pin 13. The Arduino is programmed to blink the LED at regular intervals.
