This ice warning and lights reminder electronic project circuit diagram is designed using common electronic parts .
This ice warning and lights reminder electronic project circuit diagram will tell a driver if his lights should be on and will warn him if the outside temperature is nearing zero by lighting a LED and sounding a buzzer .
This electronic touch switch circuit is based on two transistors an can activate a relay , when the touch sensor is pressed .
The touch sensor can be constructed using a small piece of a printed circuit board ( two small tracks with a 2 mm distance between each other ) .
This smoke detector circuit diagram is based on the SD2 CMOS Photo-Electric Smoke Detector Integrated Circuit manufactured by Supertex INC and include almost all needed components to build a very simple and high efficiency smoke detector project .
