Greetings readers. I have just published (live on Feb 10th) the paperbook book: Companion Code Handbook: Hello Arduino! This companion book is a handy reference with complete source code with comments for all projects detailed in the book Hello Arduino! This is a printed version of all source code required for completing all projects (and […]

An important personal milestone: Hello Arduino!
Today marks another special day in my humble life’s timeline. Today, my first ever book went live worldwide on Amazon.com (+ .uk, .de, .fr, .es, .it, .nl, .jp, .br, .ca, .mx, .au, .in as per different markets) in both eBook and paperback formats. The book titled “Hello Arduino!” is a fun book for anyone (12 […]
Creating your own light show
With programmable LED strands, strips, and rings, it’s not only satisfying and fun but also a solid learning experience for any enthusiasts. Besides, who can ever get enough of tinkering with LEDs? In this project, I connect a 24 pixel ring LED module to an Arduino board, then wrote some light effects functions in the […]
Arduino: Build a custom nightlight
In this project, I built a night light with exact parameters of my own liking using simple components. I wanted the light to come ON when I detect the ambient light to be an exact value customized for my room, stay ON exactly as long as I want, and/or blink as I wish. Additionally, I […]
Arduino: Photoresistor and Servo motor working together to indicate light
This fun project is to visually and mechanically indicate day/night or light/dimness around with the help of a photoresistor that reads the light values. And that’s connected to a motor (a servo) which has an arm/arrow connected to it and it moves to certain positions depending on the light sensed by the photoresistor. Lastly, the […]
Arduino: Building a music tempo controller with simple components
In this project, I built a simple system where we can play a tune/music through a speaker (sound/tone is of our choice) and while it’s playing, we can control the tempo in real time. For the speaker, I used an inexpensive passive buzzer hooked up to a 10K resistance potentiometer. I insert a turning knob […]
Arduino: Building your own dimmer at home
This mini-project is to get a lamp to dim or brighten on command. In this case, we’ll hook up a regular LED to a potentiometer module, which when turned clockwise will increase the brightness of the LED lamp, or dim it (and all the way to “off”) when turned counter-clockwise. This is exactly how the […]
Arduino: LED color fade project
Here’s a straight-forward circuit with a LED light that’s controlled by my code downloaded to an Arduino controller’s chip running the “light show”. It starts with red color of LED set to max RGB(255,0,0)…then slowly dims the red as green value is increased incrementally to max. Then green is dimmed while blue is increased incrementally […]
