So in this article we are trying to make a true MPPT solar charger project using Arduino which will charge a 12V battery from a solar panel and will use MPPT logic to always extract maximum power from the solar panel. That means that even when sunlight changes, we try to adjust PWM duty cycle […]
Arduino Projects
Arduino Automatic School/College Bell System
In this post I will show how to construct an automatic school bell/college bell system using Arduino, 16 x 2 display and real time clock module. You can program this project to ring the bell up to 16 times a day at your preferred hour and minute. The length of the bell ring can be […]
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 […]
2.4 GHz 10 Channel Remote Control Switch Circuit
In this post I will show how to construct a 10 channel remote control switch circuit based on ISM (industrial, Scientific and Medical) band. Introduction The ISM band is operated at 2.4 GHz, which can be used without licensing with reasonable power output. The proposed project is general purpose ON/OFF wireless switch, which can be […]
Wireless Office Call Bell Circuit
In this post I will show how to construct wireless office calling bell which can be used for calling 6 different personnel from head’s / boss’s desk or some other calling bell type fun project for your home. Using nRF24L01 2.4 GHz module We will be constructing a simple wireless calling bell using Arduino and nRF24L01 […]
Ultrasonic Fuel Level Indicator Circuit
An electronic device or circuit which detects and indicates the various fuel levels in a fuel tank without a physical contact, through ultrasonic waves, is called an ultrasonic fuel level sensor In this post I have explained how to build a simple fuel tank level indicator circuit using Arduino and ultrasonic sensors. In every vehicle […]
