A electronic buzzer is simple. But useful well worth and the price is lower than 1$. By use just a 9-volts battery only. So without worrying about electrical leakage or electric shock from 220V to buzzer. Unless also has LED will glow. Show that the circuit the normal operation as well. The working of circuit. […]
Everyone need the electronic projects that correctly works.
The collection electronic circuit to show you that not enough.
Because sometimes them may not works, so you lost times and too much money.
I need to see you happy with your projects.
Therefore, I will experiment build them to assure to you that It is really works. But this working must to use long times and a lot power. Please wait me.
Because we have more than 700 electronic projects. It may cause you difficult to find them.
I hope you will like them and come back to visit mysite again.

We’ve watched a lot of Automatic night light switch circuits. Which I like to use a transistor as base. But now we lets to see IC-op-amp. It is also very simple. As my feelings It has high sensitivity more than one, and with great high accuracy. How does it works. A light detector component, we […]
This is a simple two digit counter using CD4026 as main parts can display with LED 7 segment 0-99 number There is a reset button to restart. It can be applied to, for example, counting products, counting people into the library, and more. The working principle As circuit in Figure 1. The IC1, IC2-CD4026 4026 […]
This is simple circuit that we makes in hobby time or toys for my son but really uses. It will have sound alarm when morning like a normal clock alarm with lighting sensor same clock. We use a IC-4011 CMOS only one and a few components also can generate pulsating tone like a general clock. […]
The sound of insects such as crickets, cicadas, resulting from flutter briefly. We can use a multivibrator to connects as sound generator circuit to imitate these insects sound. Some electronic clock alarm tone also sounds similar to these insects. As Figure 1 is simple clock alarm sound generator that can assemble on a breadboard right […]
We use a simple oscillator circuit in very many projects. I like to use a inverter logic gate since it is easy and cheap. But we do not use it directly. Mostly I use IC4011 nand gates since includes for separate four positive logic nand gate on a single silicon chip. Enough for general use […]
Now I am Electronic projects circuits blogger. It is hard work and dedicated time. We certainly need an income families. Many years ago, I had main revenue from adsense. Now the sponsor is ads banner And a commission from amazon I am so thankful all my friends a lot. Some friends wanted me to sell […]
