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 […]
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 […]
Tilt Switch Interfacing Circuit with Arduino Uno
The tilt sensor acts like a small switch and changes its state when we tilt or move it; it also detects direction, movement and vibration. Here we used Arduino Uno with tilt sensor, buzzer and one LED and when sensor tilt, Arduino see it and then Arduino make buzzer ON and LED ON. Arduino Code: […]
Interfacing Hall Effect Magnetic Sensor Circuit with Arduino
Hall sensor feel magnet near it and it make signal when magnet is close, then signal can be digital or analog and here Arduino reads this signal. We can view the results on a computer or LED and the circuit checks motor speed, wheel speed or position. Arduino Code: Coding Explanation: Circuit Working: Parts List: […]
PIR Motion Detector Circuit using Arduino
Turn Arduino into a motion spy! with just a PIR sensor, buzzer and LED we can detect movement easily. Whenever someone passes, it spots movement and warns us with light and sound; this PIR Motion Detector Circuit using Arduino is for beginners and makers. Also, it is fast to build, fun to use and full […]
