Have you ever thought about home security? And implementing your own home security alarm systems? It’s one of the simplest and most interesting circuits for electronic beginners. Our new home security equipment uses an LDR (Light Depended Resistor) to detect security problems. Theft attempts and other…
This is a very useful and simple circuit diagram for amplifying the weak signals from a capacitive condenser microphone. You can use this circuit for sound sensing applications and some automatic robotic sensors. We have already posted an efficient audio amplifier circuit using 1895 IC. It is…
Today Electronic projects for school students are an essential part of their academics. These educational science experiments for kids boost their skills and analytic power rapidly to a great extent. But most of the parents and students worry about how to make…
Laser communication project circuit is a popular basic project that is a useful part of many big projects. The LM386 is a low voltage power amplifier (audio amp chip) IC. This circuit is usful in low voltage customer applications. The…
Here we are dealing with a simple powered portable audio amplifier circuit using TPA2025D1 IC chip. The TPA2025D1 is a high-efficiency Class-D audio power amplifier (mini amp) with battery tracking AGC (Automatic Gain Control) technology. We are also using an integrated Class-G boost converter that enhances efficiency at…
Snap your fingers to let happen what you want! Yes, that’s what we have ahead: at least in the realm of electrical and electronic appliances. I’ve used 555 timer to avail the monostable multivibrator functionality and 7474 D-flip flop to…
Here Circuitsgallery comes with a simple and automatic fire alarm and detection system. This fire detection alarm circuit is based on the thermistor. A simple potential divider arrangement using a thermistor is capable of sensing the temperature (presence of fire) and alerting us with a…
Production of low voltage DC power supply from AC power is the first and most important challenge faced by many electronics developers and hobbyists. The straight forward technique is the use of a step down transformer to reduce the 230 V or 110V AC…
A good regulated AC to DC power supply circuit is essential for any electronic hobbyists and electronic students to do their electronics hobby projects. Also, a bridge rectifier power supply is one of the introductory circuits for beginners. Firstly we need to know what is a…
