This project is built to monitors the instantaneous current, voltage, frequency, and real power consumption in home. To monitor voltage, the project uses a dedicated miniature transformer. Current is measured using a home built current transformer that clamps around the incoming power feed. The current transformers are homemade from split ferrite cores with 100 turns […]
This network power resetter is built based on PIC16F628 microcontroller. It controls a solid-state-relay that connecting 110VAC Power line with a satellite internet receiver or routers.
The project shows you how to build a combination lock for your home door using PIC16F84 MCU and electro-magnetic lock. A 4×4 keypad, located outside the door, is used to enter key combination. The master combination will open the door, as well as allow programming of up to four transient combinations, the illumination duration, and […]
This PIC16F628-based compass uses NMEA-0183 data from a GPS receiver. The direction indicator displayed on eight-point LED with radial pattern every 45°. Although the GPS provides accuracy to a tenth of a degree, that kind of accuracy is not really necessary in the automotive use for which project is designed.
