In this post I will show how to construct an Mp3 player using arduino and DFPlayer. The proposed article has two Mp3 player designs, one with push button control and another one with IR remote control. We will also take a look at DFPlayer (Mp3 player module) and its specifications. We all love music, we […]

How to Make TDCS Brain stimulator Circuit
In this article I will show how to construct an interesting project, which could potentially enhance your brain’s capability. I have explained how to make a TDCS brain stimulator circuit. Overview This may sound like science fiction, where an evil scientist connects his head to some complex machine and gaining super human capabilities. This may […]
3-Step Automatic Fast Battery Charger/Controller Circuit
Generally it is noticed that while charging batteries people hardly pay any special attention toward the procedures. For them charging a battery is simply connecting any DC supply with matching voltage with the battery terminals. A fast battery charger circuit charges a battery with enhanced speed so that it is charged in less time than the specified period. […]
Ultraviolet (UV) Sanitizer Circuit for Disinfecting Home Materials
In this post I have explained the making of a simple, cheap yet effective ultraviolet or UV-C home sanitizer circuit using ultra violet rays or UV-C. The idea was requested by Mr. Shah (kristin). Using UV Rays against Coronavirus The UV-C sanitizer circuit I have explained below can be effectively applied for sanitizing all external […]
Room Air Ionizer Circuit – For Pollution Free Living
In this article I have explained how to build a simple room ionizer circuit for getting a clean, pollution free environment right inside our home. Introduction Have you ever thought or wondered why atmosphere over hill stations and other similar places which are far away from modern cities give you a feeling of freshness and good health? […]
Heart Rate Monitor Circuit
In this article I will comprehensively discuss a relatively accurate electronic heart rate sensor circuit processed by a few discretely wired opamp circuit stages, and subsequently we’ll learn how this can be modified for making a heart rate monitor alarm circuit. Using IR Photodiode Sensors The sensing of the heart pulses is basically done by […]
