555 Timer IC Tester
NE555 Timer IC is very popular and one of the commonly used component in electronics circuit. NE555 Timer IC is also called Ideal IC since it offers multiple features like multipurpose functionality, low power consumption, small size and durable. When we work on a particular project and it doesn’t work the way we wanted, before circuit we doubt on the IC used, if it is working or not. More or less, blaming IC is reasonable since IC is the combination Read more […]
Dry Cell Charger | Easy Electronic Projects
We all are fed with the fact that dry cell is not rechargeable and it has no use once it is discharged during use. And, people simply throw it away and buy a new one. Because of this, people are forced to invest quite a lot on battery. In order to overcome this problem, here we have presented a new project ‘Dry Cell Charger’, which has been tested and verified practically. Using the circuit dry cell charger one can charge dry cell 6 to 8 times Read more […]
Woofer Tweeter Crossover
When using speakers, people must have faced quite a lot of problems due to failure of the speaker to produce smooth sound quality continuously. It is because speaker detects only identical frequency and does not give response to all frequency. Particular range of low frequencies is detected by the speaker and it ignores high frequencies. Woofer or tweeter is introduced as a solution to this issue. However, if the signal from amplifier is directly Read more […]
Capacitor Tester cum Flasher
Capacitors are one of the basic components in any electronic projects. Now, here we taught you, how to test capacitor either is short, open or working. The simple circuit of capacitor tester is built around two general purpose NPN transistors. This circuit posted here is used to test capacitor up to 1000 µF. The capacitor to be tested is connect at point A and B as shown in circuit diagram (positive terminal at point B where negative terminal at Read more […]
Infrared Remote Controller Using Arduino
Here is projects called “Infrared Remote Controller Using Arduino” which allow you to control any type of electrical gadget using any infrared remote control. The project posted here records an infrared message from an existing remote control and give output as required. Here, we use EEPROM memory to store the infrared signal code so that we can use this remote even arduino board is disconnected. Circuit Description of Infrared Remote Controller Read more […]

Circuit Description of LED Running Light Circuit: The entire circuit of LED running light is designed using two general purpose NPN transistors. The design and working of this circuit is very simple and straight forward. Both of these transistors are configured in astable multivibrator Read more […]
Ni-Cd Battery Charger
These days many of electrical appliances (watch, RC car, radio etc) use Ni-Cd battery. Here is a simple circuit of Ni-Cd battery charger in the series of easy electronics projects. Circuit Description and working principle of Ni-Cd Battery Charger Basically Circuit of Ni-Cd battery charger is rectifier. The input from AC mains is directly given to the circuit through resistors R1 and R2, where resistor R1 is used to limit the surge current and Read more […]
Mosquito Repeller Circuit
Here is a simple circuit called mosquito repeller in the series of easy electronic project. The circuit of mosquito repeller uses few passive components. Circuit Description and Working Principle of Mosquito Repeller: The circuit of mosquito repeller is so simple that any-one can understand. The input of 220 volt AC from mains is directly given to the circuit; two resistors are connected in parallel as current divider circuit. Neon lamp is used Read more […]
