Demonstrates the use of the analogWrite() function in fading an LED off and on. AnalogWrite uses pulse width modulation (PWM), turning a digital pin on and off very quickly, to create a fading effect. Circuit Connect the anode (the longer, positive leg) of your LED to digital output pin 9 on your Arduino through a 220-ohm resistor. Connect the cathode (the shorter, negative leg) …
Designing a custom plate for the Arduino Robot, adding jumbo LEDs and displaying readings from an ultrasonic distance sensor to the LCD. My previous post on the Arduino Robot described how I took the Runaway Robot sketch and modified it work with the PING ultrasonic distance sensor. This post is still based around the same example sketch, …
You can control your MKR1000 remotely with a RESTFUL interface. Things used in this project Hardware components Arduino MKR1000 × 1 LED (generic) × 2 Resistor 220 ohm × 2 Jumper wires (generic) × 5 Software apps and online services Arduino IDE Story It would be nice to communicate with an Arduino thru RESTFUL interface …

Things used in this project Hardware components Arduino MKR1000 × 1 LED (generic) × 3 SparkFun Pushbutton switch 12mm × 3 Breadboard (generic) × 1 Jumper wires (generic) × 1 Resistor 221 ohm × 1 Software apps and online services …
A couple of weeks ago I presented my culmination project, framed laser harp, at New York City College of Technology. Work on it was so interesting for me, that I decided to share it here. I am an Arduino amateur and don’t have any professional …
You wan’t do a dark sensor with a LDR, one transistor and one LED and you don’t know how to do it? In this small tutorial I will explain to you how you can do that even if you know only the basics of electronic. …

We are a generation that love sound and light – can’t do without them really. Our most preferred time of day is night, or what we would call evening. We are particularly well acquainted with technology; doesn’t hurt these days. Our prerequisite for everything is that it be ‘cool’. Put it all together and in …
In this project, I made an infinity mirror based on a dodecahedron that reacts to sound . Step 1: Materials Essential materials: Arduino Uno 3mm thick 100x50cm MDF 2mm thick 100x50cm plexiglass 3 meter WS2812B LEDstrip 60 LEDs/m Sound Detection Sensor Module 3-PIN Thin electric wire (10ish meter total) Breadboard Perfboard/stripboard Simple rectangular rocker switch …
You might have noticed the Slaveflash I built with an Attiny 24, the instructable can be found here: Slaveflash-trigger-for-digital-with-Attiny24 After building the first prototype I collected all my old flashes I got over the years and had four more slaveflash-triggers to built. I already figured out an PCB-Layout for the SOIC-version of the attiny 24. But the biggest …
If you’ve even seen a fake candle you have probably noticed how it doesn’t look realistic. Whether you’re trying to add some atmosphere to a dinner or light up a jack’o-lantern, your choices are limited. A real candle has a fire hazard, but a fake candle will look tacky. If only there were a safe …
