Wireless DC Motor Speed Control Circuit
In this post I will show how to construct a wireless DC motor speed control circuit which can be controlled using any IR based remote controller. The proposed project has two main objectives; the first one is 5 step sequential speed control of a 12V DC motor using IC 555 (PWM) and controlling the PWM […]
Anti Spy RF Detector Circuit – Wireless Bug Detector
A anti-spy or bug detector circuit is a device that detects hidden wireless electronic devices such as wireless microphones, spy cameras, Wi-Fi devices, GPS trackers or any gadget that emits some kind of radio frequency (RF). The proposed design can be specifically used as: Overview Also called anti spy RF sniffer, these are usually used […]
Wireless Music Level Indicator Circuit
A wireless music level indicator is an electronic device built for sensing the varying levels of a music signal and convert it into corresponding levels of illumination over an LED array bar. This simple circuit will create dazzling LED light effect by detecting any music frequency in the atmosphere and by illuminating a 10 LED […]
How to Make a Wireless Robotic Arm using Arduino
This robotic arm circuit which can be also implemented like a robotic crane, works using 6 servo motors and can be controlled through a microcontroller remote control, using an Arduino based 2.4 GHz communication link. Main Features When you are building something as sophisticated as a robotic arm, it must look modern and must include many […]
Ultrasonic Wireless Water Level Indicator – Solar Powered
An ultrasonic water level controller is a device which can detect water levels in a tank without a physical contact and send the data to a distant LED indicator in a wireless GSM mode. In this post I will show how to construct a ultrasonic based solar powered wireless water level indicator using Arduino in […]
