The post talks about an IC 4060 timer circuit problem implemented in a coffee wending machine, in which the circuit simply stops working each time its stipulated delay period is lapsed, even after a complete power switch OFF and ON. The question was presented by Mr. Kenndy and was solved through the following email discussion: […]

How to Make a Shake Powered Flashlight Circuit with Magnets and Coils
In this post I have explained a shake powered flashlight circuit using an simple copper coil and a magnet. The idea was requested by Mr. Dennis Bosco Demello The Design Electromagnetism was proved way back in 1873 my Maxwell, and later by Faraday, and amazingly the technology still forms the backbone of all the major […]
Illuminated Crosswalk Safety Light Circuit
In this article I have explained a simple illuminated crosswalk safety light circuit for ensuring a safe walking passage for the user amidst heavy traffic. The idea was requested by Mr. John. Circuit Objectives and Requirements I recently came upon your website while researching circuits for a hobby project i’m working on. I certainly admire […]
RFID Security Lock Circuit – Full Program Code and Testing Details
In this article we will see how an Arduino based RFID reader circuit could be used for controlling a relay, which in turn could be used in security door lock applications. Overview If you haven’t yet checked the previous RFID article, please go ahead check it out, it covered the basics of RFID technology. We […]
Triac Phase Control using PWM Time Proportional
A triac phase control using a PWM circuit can be useful only if it’s implemented using a time-proportional format, otherwise the response could be haphazard and inefficient. In a few of of my earlier articles as given below: Simple Remote Controlled Fan Regulator Circuit Push Button Fan Regulator with Display Circuit Dimmer Circuit for LED […]
RFID Reader Circuit using Arduino
In this article we are going to take a tour on RFID circuit technology. We will be exploring how RFID tags and readers work, how to interface RFID module (RC522) with Arduino and extract some useful information from the RFID tags. Using RFID Tags I am sure every one of you has used RFID to […]
