We’ve all heard of the smoke test, and we know that it’s the lowest possible bar for performance of an electronic device. If it doesn’t burst into flames when power is applied, you’re good to go for more functional testing. But the smoke test means something else for cars, especially those powered by diesel fuel. […]

The other day I was confronted with an interesting problem, I needed to control a series of lights from an interaction on a computer screen and it had to be as inexpensive as possible. I instantly thought of an Arduino. It had everything that I needed, more than enough I/O, an integrated USB and its only

This was my first animated Halloween prop. I found this witch at the local hardware store. It was meant to hang up by a cord and if someone came close to it, an infrared sensor would trigger the prop. The prop has LED eyes that would light up and it would trigger a voice tract

There are a host of boards based around the ESP32, and also its follow up, the ESP8266. It’s noteworthy to witness how they have evolved from the simple breakout boards they were when the chip was released back in 2015 to something a lot more major. The latest of these boards is the esp32MX-E from Modtronix Engineering, which will be raising soon on Crowd Supply. Measuring

Those old enough to have encountered punch cards in their lifetime are probably glad to be rid of their extremely low data density and the propensity of tall stacks to tip over. But obsolete as they may be, they’re a great tool to show the basics of binary data storage: the bits are easily visible

The Phenakistoscope is an early optical illusion device that uses static images to create the illusion of motion through the principle of persistence of vision. It is regarded as one of the first forms of moving media entertainment that paved the way for the motion picture industry. We are not sure how big is the

Francisca Molero Luque, Dolores Martín Cabrera and Laura Mejía Ospina, students of ‘Creative Electronics’, a Beng Electronics Engineering module at the University of Málaga, School of Telecommunications. We decide to make as final project a derivation of Interactive Geodesic LED Dome. Supplies – NeoPixel Digital RGB LED Strip – IR sensors – 470 Ohm and 10K Ohm
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

The MMORPG RuneScape holds a special place in the hearts of those who played it in the early 2000s. Sure it might seem exceptionally quaint by modern standards, but at the time it was groundbreaking stuff. Plus you could play it for free, which certainly helped get people onboard. While there’s a more modern build available, many

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
