Digital alarm clock circuit diagram
U1 is the 3817 integrated circuit. It has the ability to drive the display directly, and it can display 12h or 24h, schedule alarm sounds, timely and automatically turn on the radio. Display is FND500 light-emitting diode, the input frequency is 50H or 60Hz. U2 is the 7800 series regulator, its rated power can meet the requirements of the radio. Users can select radio playing time length ( the maximum is 59 min), then Q3 will output a low level to automatically turn off the radio. (View)
