Electronic Circuit Schematics Electronic Circuit Schematics. Note that all these links are external and we cannot provide support on the circuits or offer any guarantees to their accuracy. Some circuits would be illegal to operate in most countries and others are dangerous to construct and should not be attempted by the inexperienced. Digital Clock using PIC Microcontroller and DS1307 RTC Digital Clock using PIC Microcontroller and DS1307 RTC – Circuit Diagram I hope that you can easily understand the circuit diagram. The circuit is powered using a 5V power supply. 8MHz crystal is connected to PIC Microcontroller to provide necessary clock for the operation. Fire Alarm System using AVR Microcontroller ATMega32 AVR For example if the oscillator clock is 8Mhz, we can chose a prescalar of ‘8’ to get a 1MHz clock for counter. The prescalar is selected based on frequency. If we want more time period pulses we have to chose higher prescalar.
