Like most people I was skeptical about getting a robotic vacuum cleaner, so as a trial run I thought I would buy the now obsolete iRobot Roomba 530 which was heavily discounted (they’re still available in Australia, showing how behind the times we are). Of course, as soon as I got it home I fell […]

LED Chaser Game
Hello, my name is Vigas Balachandran and on this instructable, I will be presenting my final project. For this project, I have created a LED chaser game. In this game, the LEDs will be flashing in consecutive order. On the serial monitor on the arduino, you will be given a colour. With the given, you […]
Arduino String Case Change Functions Code
The String case change functions allow you to change the case of a String. They work just as their names imply. toUpperCase() changes the whole string to upper case characters, and toLowerCase() changes the whole String to lower case characters. Only the characters A to Z or a to z are affected. Circuit There is […]
DIY: ARDUINO SOUND SENSOR SYSTEM
I have a major problem when it comes to talking on the phone or playing video games with my friends – I often get loud (that’s quite an understatement). Since I live with my parents, this often triggers my mother and she usually ends up barging into my room to tell me to quiet down. […]
Blink LED using Arduino
This example shows the simplest thing you can do with an Arduino to see physical output: it blinks an LED. Circuit To build the circuit, attach a 220-ohm resistor to pin 13. Then attach the long leg of an LED (the positive leg, called the anode) to the resistor. Attach the short leg (the negative […]
Yogy – The Arduino Powered Robot Made For Kids
In this Instructable I will show you how to make a cute and kid friendly Obstacle Avoiding Robot I like to call Yogy. Yogy gets his name from the Yoghurt tub body he is made from. I am a sucker for seeing the best in trash and this Yoghurt tub looked too good to be […]
NeoPixel Ancient Oil Lamp
In this Instructable, we will describe how to turn a “retro” oil lamp into a NeoPixels based rechargeable lamp with colorful light effects. Supplies Arduino nano 12 bits NeoPixel ring Micro USB 5V 1A TP4056 Lithium battery charger module 3.7V 9800mAh Lipo Li-polymer Battery Rotary encoder Ec11 or KY-040 Module Self-locking square button switch An […]
Analog Write with 12 LEDs on an Arduino Mega
This example fades 12 LEDs up and the down, one by one, on an Arduino Mega board. Circuit image developed using Fritzing. For more circuit examples, see the Fritzing project page Connect the longer, positive legs of (anodes) 12 LEDs to digital pins 2-13 through 220 ohm current limiting resistors. Connect the shorter, negative legs (cathodes) to ground. Schematic Code In […]
Arduino: Portable Two-Axis Stepper Control
In a previous tutorial we have seen how to run two stepper motors synchronously from a given start position to a defined destination using an Arduino and a very simple “user interface”. That user interface was restricted to some microswitches and LEDs, both installed on a breadboard. As promised, this new instructable shows how to add a […]
Digital/Analog Clock – Arduino + PaperCraft
In this instructable we will be recreating a clock inspired by Alvin Aronson’s original design. When I first saw this clock I was very impressed by how clean an elegant the design was I immediately wanted to recreate this effect. I hope some of you feel the same and use this as a guide to be […]
