ECG is very useful in the medical community. Such as experimental research and development of bio-medical imaging. But this should not be taken with patients because we do not want that. The real purpose is that it is used to preview a heart rate only. In general measuring the rate of heartbeat will get a […]

LED Chaser by IC 4017 + IC 555

Posted: 08 Mar 2014 05:50 AM PST

If you want to build a 10 LED Chaser circuit we suggest this circuit first. It uses popular IC is a simple and affordable IC-4017_decade counter and IC-555. As Figure 1 is LED chaser circuit whicn The CD4017 act as LED driver in 10 output, by LED will glow only one in a rapid sequence. […]

If you get the job From teaching science to electronics projects. Elementary education level. This project is right. Is the LED roulette circuits. They uses the principles of digital ICs.Create an integrated LED flashing to the rhythm. And then stopped at one of the LED. Enjoy creating game. And knowledge From digital ICs. Principles of […]

CD4017 CMOS-Decade counter/divider

Posted: 08 Mar 2014 12:26 AM PST

CD4017 CMOS-Decade counter/divider When we build the 10 LEDs running light for hobby. Often use CD4017 CMOS-IC. This really neat chip contains a counter and a decoder circuit, that can show a single output pin for each count from 0 to 9. And also use to build all kinds of timer, LED sequencers and controllers […]
