Do you want to finish class early? Set the timer or immediately trigger the bell: your teacher and the other students will think that it's the end of class. Or another joke: discreetly install the application on the phone of a friend and set the timer so that it goes off. The sound perfectly imitates a school bell. Ideal for pranks.
• Press the button to start the timer or trigger the buzzer.
• Set the timer.
• Change the background color and the LEDs
