Now days USB power source is very common and available in many devices and power banks. This DC-DC converter provide -5V negative voltage from +5V USB power source. This converter can be used in a wide range of industrial automation control equipment, sensors, isolated operational...

In our last tutorial, we examined how to create a menu for your Arduino project on a Nokia 5110 LCD, with push buttons to navigate through it. In today's tutorial, we will build a modified version of it which will make use a rotary encoder (in place of the push buttons) for menu...

We can say that an Interrupt is an automatic transfer of software execution in response to a hardware event that is asynchronous with the current software execution. As it's name says, interrupts, "interrupt" the normal program flow to perform an action (run another code block, function,...

We have published quite a number of tutorials using different displays with the Arduino, with the most recent being the tutorial on displaying graphics on all kind of displays with Arduino. For today's tutorial, we will look into achieving more with displays by implementing a menu based...

Over the last few articles, we have covered the use of ESP8266 boards for building several WiFi based projects. For today’s tutorial, we will look at it's recently released successor; the ESP32. As mentioned in previous tutorials, ESP-12e module popularly referred as the...

A low-cost, easy-to-build, high-power LED controller with a built-in programmable timer. The main objective of this project is to design a maintenance free and low-cost light which automatically turns on and off at the predetermined time of the day. This kind of light helps...

15 A 100V Isolated Half bridge driver project intended to be used for DC-DC converters, inverters, LED driver and motor driver applications. This projects is really helpful in industrial applications where noise is a concern since project provides optical isolation between...

This project includes 10 LEDs of 1W each, and provides high intensity lighting that can be used in various applications. The board is made in Arduino shield form and can be used with Arduino Uno or Mega. Each LED can be controlled individually connected to digital pins D2-D11 of...
