This project for Arduino 2-Step Programmable Timer Circuit with Independent Output Delay Adjustment uses Arduino microcontroller to make simple timer. Not like normal timer with two outputs as this one uses only one output. It switch between two states. And each state have delay which we can change for different use. Circuit Working: Parts List: […]
Battery Status Indicator Circuit using Flashing LED
Battery Status Indicator Circuit using Flashing LED is an easy to make project. Circuit uses BC547 and BC557 transistor, some resistors, capacitors, one diode and one LED. LED show battery condition by blinking light. It work with 6 to 12V battery and it is easy way to know battery health and it ensures it works […]
Simple FM Radio Jammer Circuit
Simple FM Radio Jammer Circuit make signal to block normal FM radio. It send noise or fake signal on same frequency so real FM signal get disturbed. Main parts: Transistor work like oscillator and make RF signal. Coil and capacitor set the frequency of this signal. Change trimmer capacitor to change jammer frequency inside FM […]
50 Watts Audio Amplifier Circuit
To get good sound with less power and work for long time is very important in audio amplifier. This 50 Watts Audio Amplifier Circuit give strong sound and work well. It uses both MOSFET and BJT to make clear sound and can run 8 ohm speaker with full 50 watt power. Circuit Working: Parts List: […]
10 Watts MOSFET Audio Amplifier Circuit
This 10 Watts MOSFET Audio Amplifier Circuit give about 10W power. It good for playing sound on low impedance speaker. It use two BC547 transistors to drive signal and IRF540 with IRF9540 MOSFETs for output power. BJT transistors make signal strong and MOSFETs give good power. Together they work well for audio amp. Circuit also […]
18 Watt MOSFET Audio Amplifier Circuit
18 Watt MOSFET Audio Amplifier Circuit is good for home sound, small PA or personal audio work. It give medium power to sound signal. This amplifier uses MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor). It have many good things like to stay cool, less sound problem and work efficient. MOSFET is 3-pin part which is used in many […]
