Remote Controlled ATS Circuit – Wireless Grid/Generator Changeover
In this post I have explained a remote controlled automatic transfer switch for enabling an automatic grid to generator changeover action from a specified distance. The idea was requested by Mr. odudu johnson. Technical Specifications Project description: Automatic changeover switch with wireless generator control abilities or mechanism.The generator rating is going to be between 2.2kva […]
Cellphone Controlled Car Starter Circuit
The post presents a simple cellphone triggered remote control circuit that can be applied as a cellphone operated remote car starter. The unit would cost less than $20 to build. I have already covered quite a few interesting cellphone remote control circuits in this blog, all of which can be implemented to control or toggle […]
Light Controlled Sound Effect Generator Circuit
This unique circuit allows you to create many different sound effect outputs simply by moving your hands over a couple of light dependent resistors, by varying the intensity of incident light over the LDRs. By Ramesh Powar The generator has two different cells LDRs that control a sound – burst oscillator circuit. One LDR controls the tone […]
Joystick Controlled 2.4 GHz RC Car Using Arduino
In this post I will show how to construct a car robot which can be controlled using a joystick on 2.4 GHz wireless communication link. The proposed project is not only made as a RC car, but you can add your projects such as surveillance camera etc. on the car. Overview The project is divided […]
Mobile Phone Controlled Robot Car Using DTMF Module
In this project we are going to control a manual robot through our cellphone using DTMF module and Arduino. By: Ankit Negi, Kanishk Godiyal and Navneet Singh sajwan INTRODUCTION In this project two cell phones, one for calling and one for receiving the call are used. The phone receiving the call is connected to the robot […]
