Arduino Projects

Arduino is one of the most exciting embedded development board evolved from the open source community to learn  and build arduino projects for hobbyists and electronic enthusiasts. It is the best resource for making DIY projects and Prototypes.

The Arduino makes use of different Microprocessors and on-chip microcontrollers to design devices that interact with the sensors and actuators.

The most popular variants of Arduino are Arduino UNO, Arduino YUN, Arduino LEONARDO, Arduino NANO, Arduino MEGA.

Arduino comes with prebuilt shields for ease of interfacing various add-on modules like GSM/GPRS shield, Ethernet shield, USB shield, and Wireless shield for IOT projects.

Quick OLED Thermometer v1

After getting my new soldering iron tip thermometer, I got inspired by that idea and decided to design a quick digital thermometer for general use. By the way, the soldering iron tip thermometer is an […]

Arduino Audio – Refined Primer

At this time, we’re going to generate various sounds using an Arduino microcontroller! We’ll initially make sound using a regular piezoelectric buzzer which makes use of a material that has piezoelectric properties. When a material […]

I2C LED Knight Rider

I have already posted two Knight Rider and Larsen Scanner LED projects online. You can go through these to access them Arduino Knight Rider Arduino Larson Scanner. Or you can buy yourself an inexpensive Knight […]

Tricolor Temperature Display

Quite recently I got a stainless-steel vacuum flask with a digital temperature readout integrated on its top lid. When I touch the top of the lid it simply displays the inside temperature of the container […]

Poor man’s Blow Switch

You may often see the musical instrument Melodica on stage shows. From Wikipedia (https://en.wikipedia.org/wiki/Melodica) melodica is a small, light, and portable free-reed instrument similar to the pump organ and harmonica. It has a musical keyboard […]

Arduino LED Signal Wand Light

This is an update to an old project of mine that was printed almost a decade ago! Here is the link to that little nostalgic project https://www.electronicsforu.com/electronics-projects/portable-signal-wand At this point, I’m using a microcontroller as […]

Backpack LED Patch (v2)

After posting the Backpack NeoPixel LED Safety Light project (https://www.codrey.com/arduino-projects/backpack-neopixel-led-safety-light/), I received a lot of requests to publish another do it yourself project based on regular light-emitting diodes, instead of using NeoPixel LEDs. So, I […]
