Simple Decimal Counter Circuit
In this article for Simple Decimal Counter Circuit instead of count in binary (0 to 1) the decimal counter count in base is 10 (0 to 9). Also, one simple and main way to make it is use Decade Counter IC which is good for beginners. Furthermore, the IC like 4017 is easy to find […]
Automobile Brake Failure Indicator Circuit
Automobile Brake Failure Indicator Circuit is backup system, which tell driver if brake system have a problem; as it uses electric parts to check brake and if problem comes then it show light or make sound. Furthermore, this circuit work only in cars with negative grounding and it also give signal if brake switch does […]
24V Flasher Circuit
24V Flasher Circuit can ON-OFF 24V thing like lightbulb again and again and we can use to turn signal or warning flash light also. Furthermore, this circuit uses IC 555 which is common for making timer or flasher and we can also change flash speed by adding resistor and capacitor to IC 555. Hence, this […]
