Hello friends, I have been hearing from friends that needs to build a simple electronic projects and cheap. Which I also like them,and collect these basic projects in : Mini Projects and Cool Projects The electronics Projects work surely. Because I know that you need to have great experience in Electronics. But in these Categories […]
Thanks for visiting our sites.
We intend to collect the electronic circuit and projects as much as possible.
Because we have many posts. So,you maybe hard to find them.

The movement lasted only one. Did not reach the detection accuracy of Pyroelectric. As product of a Passive infrared detector PIR. It will detect the change of the infrared radiation emitted by people or animals in motion. And the dictates that run the sirens or devices as needed. Principles of PIR. People or animals in […]
This circuit can prevent a car theft. By the delaying them, not to steal our cars easily. Which can use in both cars and motorcycles, that uses a battery 12 volts and also cheaper too. The working principle. In Figure 1 is the Car burglar system with start delay. When we apply a voltage supply […]
This circuit has 2 input and if both it’s input is “1” (+12 volt) What will happen?, If some input voltage is “0” (such as input A) transistor T5 will conduct a current and as cause to transistors T1 and T4 also conducts, and makes the DC motor running In one direction. When it comes […]
The electronics are still used to use a frequency generator circuit beuause It is important. And are used a lot in electronic circuits, both sine, square wave and more. In every time related to the frequency. What that we want to know is how much frequency. For laboratory common standards. We have many tools available […]
