This article explains about a Darkness Activated LED Circuit which is useful device that saves power, also it is energy efficient circuit because light glows only in darkness. The circuit automatically turns the light ON at night and OFF during the day, so we never need a manual switch for daily operation; also the circuit […]
Fan Start 10 Second Delay Timer Circuit
In many homes and industries sometimes a fan does not turn ON immediately, here, a fan start delay timer is a circuit that delays the fan start. When we apply power, the fan remains OFF for approximately 10 seconds and then turns ON automatically. Also, we can easily adjust the delay time if required. This […]

Also, it uses common parts like BC547 transistors, resistor and capacitor and because of simple design, beginners can also understand it easily. Therefore, this 30 Minute Delay Timer Circuit using Transistors is useful for applications […]
Transistor Based Coin Toss Game Circuit
Sometimes we need to make a quick decision but choosing is not easy, so we flip a coin; now imagine doing the same with electronics. This transistor-based coin toss game circuit works like a real coin toss and produces a random result every time, and when we apply power to the circuit, no one can […]
Automatic Solar LED Light Circuit
Solar power is free energy and it comes from the sun, it is clean and is renewable, because of this solar lights are very popular today; also this is Automatic Solar LED Light Circuit and it turns ON light at night, and it turns OFF light at day automatically. This circuit requires no switch, making […]
Transistor Based LED Chasing Flashing Circuit
Building a transistor-based LED chasing flashing circuit is a simple and interesting project, as this circuit switches LEDs ON and OFF sequentially to create a chasing effect, which gives it the name “chaser circuit This circuit uses simple transistors instead of ICs, making it easy for beginners to learn, it is suitable for learning and […]
