    Test Human Reaction Time with the 555 IC

    With this simple circuit that is built with the 555 IC you can test human reaction time. You can find out how fast do you react by trying to catch a flashing LED. How does the human reaction tester works? When S1 is ON the circuit acts as a astable multivibrator and the LED is lit for about 0.1 second and is flashing every 1.5...

    Fritzing Software Download

    Fritzing software is an interesting open-source initiative to support designers, artists, researchers and hobbyists to work creatively with interactive electronics and develop electronic projects. Fritzing helps you learn more about electronic circuits, to document your projects and even let’s you prepare them for...

    ON OFF Touch Switch with 555

    This ON OFF touch switch circuit is based on the well known timer IC 555 (IC1), which drives a relay that acts like a switch. The metal surfaces can have what form we want, but it should be clean and very close to the circuit. Touch plate MP1 in order to close the contact of relay RL1 [ON], or plate MP2 in order to open the...

    Top 10 Electronic Circuits January 2013

    Here are the top 10 electronic circuits of January 2013. This top is made using data from Google Analytics. I hope this year I will publish it every month. January 2013 Top 10 Security light and switch with PIR This is a simple update to Mr. Hareendran’s PIR Sensor Security Light circuit. It has a shortcoming limits the relay...

    7402 Datasheet

    7402 IC is a device containing four independent gates each of which performs the logic NOR function. 7402 package options include: plastic small outline, ceramic chip carriers, flat packages, plastic and ceramic DIPs. The SN7402, SN74LS02 and SN74S02 are characterized for operation from 0°C to 70°C. 7402 connection...
