Sometimes I just have those days where I really want to make something neat with the Arduino I have lying around, but I know I don’t have the patience for a more involved project that’ll take more than a day or so. This is for one of those days. The premise is as follows: A …
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) …
So what I want to do here is do several things with two LEDs with speech recognition I’m using bitvoicer you can get it here Step 1: Part List So I’m doing this with as little parts as I can, here’s the list: Green LED Red LED Breadboard 1k Resistor Jumper Cables Computer Computer Mic(you can …
Small enough to slip in a mint tin, yet loud enough to be heard across a house at only a few dollars per unit. A nice combination for a pretty good prank! Let’s dive in! Step One: The Circuit You can purchase the printed circuit board from OSH Park using the link in the parts …

Stand out from the crowd with this unabashedly ostentatious excuse for a wallet. It’s got plenty of space, RGB lights, and you can even put your name on it for added vanity. Interested? Keep reading! In the files section of this build you can find two things: a Fusion archive and some STL files. If …
Persistence of vision is an optical illusion, it works on a simple phenomenon how our day to day television works. MY first pov was six months before with arduino uno and with motor. However it is best to have a small and portable device that can be carried anywhere and image can be seen without …
Introduction I’ve been fascinated with joule thief circuits since I made my first one. It’s amazing what all you can power from a single AA or AAA battery. The only problem is you can’t do much beyond light up an LED because the current isn’t “always on”. With a couple of extra components, you can …
Story A bit of background. My brother came to me with an odd box that a friend of his asked someone to make so that they can determine the fastest contestant to push a button. The box consisted of some LEDs, two buttons, and two sets of bicycle bells that made some weird noises. It …

Be a bright spark, lights off till it’s dark!” sometimes we forget to turn off the lights and waste electricity and you must have also seen street light turned on in the day. We have already built few circuits on Dark detector where lights turn off automatically if it is bright outside and turns ON if it …

What if we can generate different colors using a single RGB led and make our room’s corner more attractive? So, here is a simple Arduino based color mixing lamp which can change color when there is change in light in the room. So this lamp will automatically will changes its color according to the light conditions in the room. …
