The project is a 4-digit LED voltmeter and frequency counter that was previously based on PIC16C71 but was replaced by 28-pin device PIC16F876. The PIC16F876 is capable of driving 4-digit LED in ...
The project aims to construct a 9-digit pulse counter based on MC14453 3-digit BCD counter in order to count the number of pulses arriving at the input of the circuit. The MC14453 3-digit BCD counter ...
