Recently I’ve been learning about Ultrasonic waves and how to harness their power. It’s simple enough to make some type of sonar device, but I wanted to take at a step cooler and see if I could use Ultrasonic waves to not only detect movement, but also the direction of that movement. So let’s take […]

Interrupts are an extremely useful, yet often feared element of microprocessors. Interrupts allow you to run a program, while still being able to react to asynchronous input from the outside world. On many platforms they can be confusing to implement, but the arduino makes it easy! In this week’s episode, I’ll show you how to use
Arduino Interrupts and Debouncing Continue Reading
A simple server that distributes any incoming messages to all connected clients. To use, open a terminal window, telnet to your devices IP address, and type away. Any incoming text will be sent to all connected clients (including the one typing). Additionally, you will be able to see the client’s input in your serial monitor

This instructable will guide you through the process of building a set of automaton monkeys in the style of “Hear No Evil, See No Evil, Speak No Evil.” Our design ends with two monkeys reacting at the push of a button located in the Speak No Evil Monkeys eye. This design can be extended to

First of all,this is my first Instructable, and I’m not a native English speaker (or writer), therefore I apologize in advance for the overall low quality . However, I hope that this tutorial can be helpful for people using a heart rate (HR) monitor system (composed by a chest strap belt transmitter and a receiver
In this Instructable, I’ll be explaining how to build a motion activated alarm! It uses an Arduino microcontroller, a PIR (passive infrared) sensor, and a type of alarm. You can use an LED indicator, a buzzer, or a piezo. That’s the easy part. I will also be showing how to display to a character LCD

Why another spot welder project? Building a spot welder is one of the (arguably few) cases in which you can build something for a fraction of the price of the commercial version with comparable quality. And even if build-before-buy were not a winning strategy, it is a lot of fun! So I decided to embark

MaKey Makey is a project created by Eric Rosenbaum und Jay Silver. It’s an Arduino based keyboard. A very special keyboard, because you can use apples, bananas or Play Doh as keyboard keys. Sounds strange, but it works very well. How it works: The trick is using a very high resistor on the Arduino input (10..50MOhm).

If you grew up in the early 1980’s and were into video games, you probably had an Atari 2600, ColecoVision, or similar game console. The controllers or joysticks for each of these systems had a distinct feel that is different from today’s game consoles or PC game controllers. If you find yourself longing to plug

There are lots of Instructables on how to use SSD1306-based 128×64 OLED displays. Many of these write-ups are very informative but just about all of them look like an unfinished science project. (In fairness, most are directed at getting up and running with the display, not creating a finished product). Here’s a quick and easy way to
