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…
This DIY PIC programmer is a part of our PIC programming basics tutorial. By using this USB PIC programmer, you can program microchip PIC series of 10F, 12F, 16F, 18F, 24F, 30F. This is also an EEPROM programmer as it supports 12Cxx EEPROM. The…
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…
Hi there! Today let’s make an Arduino project without having a real Arduino board! Yes, it’s possible by dint of Arduino simulator using Proteus library. Maybe you have already seen (or will see) Arduino programming in some of my articles. Arduino is…
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…
Variable power supplies are available in different ranges but they provide a very low current of one or two amperes. They can’t drive high power devices like a motor or high power lamps. So to get through such problems I…
The transistor is a semiconductor device used for the switching and amplification of weak signals. This article explains how does a transistor acts as a switch and the working of a transistor as a switch. At present, transistors are applied…
