It might be dangerous to tamper with electrical cables, particularly if you are unfamiliar with electronics, if not used properly electricity may be hazardous. Therefore, being secure is crucial! to prevent injury, you should determine whether there is any residual electricity (leakage voltage) before handling electrical lines. Using a IC 555 chip and other common […]
Power Supply Circuits
3V to 9V Dual Power Supply Circuit
An IC 555 is used in a reasonably simple circuit to provide both positive and negative voltage outputs from a single 3V source, such as two AA batteries in a 3V to 9V dual power supply circuit. The 555 IC set up as an astable multivibrator is used in the circuit. This indicates that it […]
Simple Voltage Follower Circuit using Op-amp IC 741
The operational amplifier (op-amp) in a voltage follower circuit produces an output voltage that precisely follows the input voltage. It is also referred to as a buffer amplifier or unity gain amplifier. Because of its price and adaptability, the IC 741 is a popular option for op amp. The high input impedance and low output […]
How to Build a Mini Tesla Coil Circuit
A Tesla coil is a device that generates high voltage and low current energy, this mini tesla coil circuit is a scaled down version of the original tesla coil. You may light up little things or produce tiny sparks using mini tesla coils, which are usually powered by a 9V battery or another low voltage […]
Buck Converter Circuit for Converting 12V to 3V
A buck converter circuit well known as as a step down converter is a workhorse in electronics. It takes a higher DC voltage and reduces it to a lower DC voltage. Imagine it like a voltage reducer valve for electricity. They are commonly used for laptops and phones because they efficiently bring down battery voltage […]
How to Convert 5V to 3.3V Circuit
Have you ever tried to use a toy that needs less power 3.3V with a charger that gives too much power 5V? A 5V to 3.3V converter circuit is like a special adapter. It takes the strong power 5V and weakens it 3.3V to the perfect level for your electronic device. This is useful when […]
