Simple NAND Gate Circuit using Transistors
An essential component of digital logic circuits is the NAND gate. It operates in the opposite way from an AND gate, only producing a HIGH output when any of its inputs are LOW. It is interesting to note that NAND gates are considered to be a ‘universal gate’ since they may be used to construct […]
Simple Traffic Signal Lights Circuit using IC 555
An electrical project known as Simple Traffic Signal Lights Circuit using IC 555 uses an easily accessible component known as the 555 IC to simulate a simple traffic signal sequence with the help of LEDs. Circuit Working: Parts List: Category Description Quantity Wattage Resistors 470Ω, 100k, 47k 1 each 1/4 watt 220Ω 2 1/4 watt […]
Simple Digital Dice Circuit
An electronic substitute for the conventional six sided dice used in games is a Digital Dice Circuit. It simulates the roll of actual dice by using electrical components to produce a random number between 1 and 6. Circuit Working: Parts List: Component Type Value Quantity Resistors (All resistors are 1/4 watt) 1k 2 100k 1 […]
Simple Low Battery Indicator with Buzzer Circuit
This circuit is simple as it relies on a fundamental idea and has a small number of components. The alerting mechanism, which beeps to inform you to a low battery is referred to as the ‘buzzer’ in the name. Overall, by clearly audibly alerting you when the battery needs to be changed, this circuit helps […]
Simplest Blown Fuse Indicator Circuit
This circuit helps you easily identify a blown fuse without manually checking the fuse itself. When the fuse is intact a green LED lights up signifying normal operation. But if the fuse blows the circuit path opens and a red LED illuminates, indicating a blown fuse that needs replacing. Circuit Working: Parts List: Component Description […]
