We have many ways to make the function generator. Using NE566/LM566 is a good choice. Because it easy to use. It looks like a NE555 timer. And we often use the NE566 as Voltage controlled oscillator or VCO circuit. It is a type of oscillator. We can control the frequency of the output with the … Read more
Here are the function generation circuit lists. Why use them? They are suitable for use or test the various electronic circuits. These circuits can generate 2 or 3 waveforms such as square wave, triangle, and sine waves from 1Hz up to 1MHz. In different amplitude. You can use a lot of components, transistors, instant ICs, Op-amp, … Read more
This is an Infrared Intruder Alarm circuit that interesting. Imagine some people walk through restricted areas. At that moment, this circuit immediately sounded to alert you. It uses the principle of cut the infrared light. The circuit will recognize, control relay runs, and turns on a warning signal like a siren for us to hear. … Read more
This simple digital voltmeter circuit diagram is a saving, easy to use Because it is smaller than a typical circuit, I believe that after I presented this circuit. You will certainly like it.
