What Is FM Transmitter? A personal FM transmitter is a low-power FM radio transmitter that broadcasts a signal from a portable audio device (such as an MP3 player) to a standard FM radio. … They are often used in cars but may also be in fixed locations such as broadcasting from a computer sound card throughout a building. FM TRANSMITTERS. They can be […]

Automatic Water Pump Controller With Water Level Indicator I am using two different circuits for this. I made the Water Level Indicator circuit with IC ULN 2003.2nd circuit for Pump Control made with IC555. This circuit will off the pump when Tank is Full and you set up the Water Level where you want to

Electric shock Gloves Circuit Disclaimer: You should only use this for self-defense purposes and not for offensive acts. Especially don’t use it on friendly animals like pets, that’s just messed up. I am not responsible for vigilante use either (you know its awesome, but still illegal). You can test it on yourself just to see

Soil Moisture Sensor Circuit A variety of humidity tester circuits are available, but this is a circuit that is as simple as possible. Using only a transistor, LED and resistor, this Simple Soil Moisture sensor circuit can be used to check the humidity level of materials like soil, paper, etc. In this circuit, we have used

What Is Li-Fi Audio Transmission? Hello Friends! Today we are going to perform an experiment on Li-Fi. First I’m going to tell you in brief about the Li-Fi project. Li-Fi (short for light fidelity) is a wireless communication technology which utilizes light to transmit data and position between devices. The term was first introduced by Harald Haas during

What Is Water Level Indicator ? The water level indicator circuit is defined as a system that gets information about the water level in tanks. By using the water level indicator with alarm circuit diagram we can overcome the overflow of water from the tankers. A water level indicator alarm circuit is a system that

What Is Clap Switch ? Clap switch is an interesting hobby circuit which turns on the lights with a clap sound. Condenser Mic basically converts sound energy into electrical energy, that in turns used to trigger IC 4017, through a Transistor.This is the Simplest Clap Switch Circuit diagram. Clap Switch Circuit Diagram Using IC 4017 Parts

Digital Dice Circuit Hello Guys, today i will show you how to make digital dice circuit diagram using 555 timer and using ic 4017. For playing that when we turn on power supply to circuit. The LED will glow at either portion, since 1-6 LED, as place of real dice.  When we press switch, all LED(7

What Is Tesla Coil ? The Tesla Coil we’ve got here is on the smaller side, producing a few hundred thousand volts of electricity. It’s pretty neat because it can actually light up a fluorescent bulb that you hold in your hand! Now, let’s dive into how the Tesla coil circuit works. When you bring
