STOPWATCH CIRCUIT

Authors at the bowling alley I have to use a 60-second timer circuit rules should prepare 60sec. ball in the need to throw 🙂 Anyway circuit pic16f876 microcontroller based on the output of the 2N2222 transistors with a strengthened SMD LEDs are driven writer stopwatch circuit oversized display has not used instead SMD LEDs display prepare software mikroC prepared with the C source and hex code are also proteus isis simulation files pcb drawings there is

Circuit power up the “START” button is pressed 15sec countdown begins. stayed 1 .2 seconds, buzzer, raspy singing meanwhile counting buzzer is silent when the time expires buzzer, 1 .2 seconds seconds long term singing and counter back to the beginning in addition reset and re-count-Buttons there …
