This is a chronological account of a project I am working on: to design and build my own digital clock. I was inspired by the KABtronics Transisitor Clock. That one is made completely from discrete components, but I wanted to do something less ambitious. I.... -
The complete circuit diagram is shown in Fig. 1. Heart of the system is lC2, National`s MM5402 clock chip. It is an MOS monolithic large scale integrated circuit. It`s pin configuration is shown in Fig. 2. The supply is derived from the mains through a.... -
To start in 24 seconds; 24s LOAD SW and Reset SW should be push simultaneously. If not, the count will start in 99. Pulse input can be connected to 555 astable multivibrator but must be calibrated for real time clock. The PAUSE SW must have a Switch.... -
Digital clock project based on the PIC16C54 microcontroller can be designed using the following circuit diagram. This digital clock electronic project based on the PIC16C54 is a simple time-of-day clock incorporating four seven-segment LED displays and three.... -
This is a combination digital clock timer and solar panel charge controller used to maintain a deep cycle battery from a solar panel. The timer output is used to control a 12 volt load for a 32 minute time interval each day. Start time is set using 9 dip.... -
