We are nation of obsessive counters: of pulse, steps, followers and calories. Most of these numbers mean little as physiology cannot be reduced to these metrics. But we try and I wondered how do we count a breath? Remember the cinematic days before hospital demise a cold mirror was a crude indicator of expiring breath. […]

Hey there! This is my first Instructable. The Quiz buzzer plans kicked off when my colleague, who also hosts a game show asked for people who could build a Quiz Buzzer. I took upon this project and with the help of few friends (Blaze and Errol) and Arduino i was able to accomplish this. Currently,

I built this Arduino based automatic LED light controller for a set of poorly lit stairs in our new home. The stairs are quite dangerous – especially at night – but not any more thanks to the Motion Activated Automatic LED Stair Lighting with Arduino (a.k.a. “the stair butler”). By carefully positioning the LED’s and

The key to my apartment never worked quite right because it is a copy of a copy of a copy. I am fairly certain that the dead bolt is original to the building and the property manager seems to have lost the original key years ago. As a result unlocking the door was always a

In my first Instructable Motion Activated Automatic LED Stair Lights with Arduino I mentioned the use of “Cooperative Multitasking”. So what is it and why is it helpful? This Instructable attempts to answer the “what is it” and “why is it helpful” question with a simple example that step by step builds up into a more complex

After building some of these: https://www.instructables.com/id/Matrix-LED-Light/ i’ve decided to bring the candle onto another level. While the first one looks good, it does look a little bit too much like the original. Nothing against the first design. It looks cool and modern. My new approach is a little bit warmer and uses different materials. Still

Surfing is an activity predominantly enjoyed during the day, primarily for reasons of warmth and water safety. Of course, if you prefer to carve the waves at night, you might enjoy the latest project from [Moritz Sivers] – a surfboard kitted out with motion-reactive LEDs. The build consists of a regular surfboard, with a channel cut

The Ultrasonic Theremin is an Arduino project that uses a cheap theremin to teach sound waves. By changing the distance of my hand to the device, I am changing the frequency of the sound waves. Also, moving a potentiometer changes the amplitude of the wave. This can be used as a science lesson about sound
