Using codes for security has been a popular trend recently. A similar type of electronic project is presented right below called the electronic code lock circuit which ensures the use of four digits in the code locking process and these codes are keyed in remotely. The code can be unlocked easily by pressing the right keys and if someone presses the wrong keys, it resets the lock automatically. The complete phenomenon of the electronic code lock systems has been described briefly in the further paragraph. Description and Working of Electronic…

The Mains Supply interruption indicator circuit can be used in applications where it is necessary to know whether the mains supply has been continuous or not. The circuit mains supply interruption indicator will be useful for monitoring mains supplies to recording equipment, especially in the recording of computer software tapes, where the slightest interruption in the mains supply will cause an error in the data being recorded. It can also be used with digital clocks working on mains. An interruption in the mains supply will cause an LED to flash…

Mans are born of habit, and we all want comfortable. At night while sleeping we often switch of the light. But sometime we used to increase or decrease the speed of fan. And it is very difficult to trace the switch board in a dark room at night and to wake-up from bed is also irrigative. By keeping this problem in mind the group of electronics geek at Dreamlover technology designed and verified a electronics project called light controlled digital fan regulator circuit. You can also check this awesome project IR…

What are Frequency Generator and Divider Circuit? A frequency generator is a circuit that generates a frequency and a divider circuit divides the generated frequency with various factors to get different frequency values. Various assembled frequency generators and divider circuits are available in the market but they are quite expensive to buy. The group of electronics geeks at dream lover technology designs a low-cost square wave signal generator and divider circuit. The frequency of 1 Hz, 10 Hz, 100 Hz, 1 kHz, 100 kHz, and 1 MHz are obtained at…

While returning home on a cold winter night it can be really frustrating if one is unable to unlock the gate due to insufficient light. A simple, economic yet reliable solution to the problem is provided by the project “Automatic Gate Light Circuit”. When it is quite dark, a slightly pressure on the bell switches the gate lights on for a preset interval of time. The project automatic gate light circuit is also a valuable addition to domestic security arrangements as it deters unwelcome caller. Description of Automatic Gate Light…
