Electric bill increasing day by day; so we need smart way to measure power use. Here is a simple project using Arduino UNO, ACS712 current sensor and 16×2 LCD with I2C and it shows real time current, voltage and power. Also, this project for Smart Energy Meter Circuit with Arduino UNO help to monitor load […]
LED Binary Counter Circuit
This project is for LED Binary Counter Circuit, which uses IC 555 timer as clock pulse generator and it also uses 74HC4040 binary counter IC. The LEDs connect to the outputs to display the binary count and the circuit operates from a 6 V battery or a DC power supply. Circuit Working: Parts List: Components […]
Audio Spectrum Analyzer Circuit using IC MSGEQ7
Music is not only meant to be heard; it can also be seen and with the MSGEQ7 chip, we can make music dance through lights. IC MSGEQ7 is an integrated circuit designed for audio spectrum analysis and it divides an audio signal into seven frequency bands and produces an output voltage proportional to the signal […]
RGB LED Color Control Circuit with LDR and Arduino
Do anyone like lamps that change color with magic? then this project for RGB LED Color Control Circuit with LDR and Arduino makes its real. Using RGB LED and three LDR light sensors, we can create a smart lamp that mix colors based on light around it. Just a simple circuit and with some code, […]
Arduino Based GPS Digital Clock Circuit
Normal digital clock use RTC chip or manual setting, but the problem is RTC needs drift and reset. So here Arduino Based GPS Digital Clock Circuit solves the problem; GPS talk with satellite and always give exact time, then Arduino read GPS time and show on LCD. So clock is never wrong, as it always […]
Small UPS Circuit for Router Backup
Never lose connection again, make this Small UPS Circuit for Router Backup. When a power cut occurs, the internet goes off and the router and modem stop working; therefore, a small UPS can solve this problem. This give backup to DSL modem and WiFi router and also this circuit is with simple parts, easy to […]
