In this article, we go over how to build a piezo knock sensor circuit. A knock sensor is a sensor which produces a voltage in response to some type of physical stress such as a knock or vibration. This is why it’s called a knock sensor; it detects knocks. This sensor can be useful when […]
Projects
Simulating Logic Gates
Introduction This project is a simple way of using the Arduino to simulate the behaviour of logic gates. Logic gates are explained on this page. The project does not actually carry out the function of the logic gate, just turns a light on or off based on one or two inputs. Effectively showing the truth […]
Tri-State Logic
Introduction So far we have sent one of two values to any Arduino output pin, either HIGH or LOW. This project shows how we can exploit a third state of the Arduino pins to reduce the number of pins needed to control LEDs. In the project, we’ll control 2 LEDs using only one Arduino pin. […]
Make A Coin slot detector Using Arduino
When your coin slot is exposed, this wearable hip-pack vibrates that area to make you aware of it. You decide to cover up, or let it all hang out. The coin slot detector is a simple way to tackle the complicated modern problem low-rise jeans can cause. with this hip pack, now your coin slot […]
Polargraph Drawing Machine
This machine, a variation on the hanging-pen plotter is a conspicuous and wilfully naive attempt to break out of the pristine, pixel perfect, colour-corrected space that exists inside our computers. It’s a drawing machine, that takes a pen (a human tool) and uses it to draw in a singularly robotic way, with some grand results. […]
Turn your Arduino into a Magnetic Card Reader!
Everyone has used a magnetic card reader, I believe. I mean, who carries cash these days? They’re not difficult to get your hands on, either, and during a trip to my favorite local electronics shop, I found a bin full of these guys. So….of course, I picked one up and brought it home to see […]
Arduino Sous-Vide Cooker
Sous-vide cooking allows you to precisely control the temperature of cooked food (how “doneness” is measured) by immersing it in a carefully controlled water bath. It’s possible, but seriously difficult, to do this just with a thermometer and a pot on the stove… but if you have an Arduino do all the hard work for […]
Basic Projects using chipKIT Uno32
Happy Tuesday, everyone! I tend to get excited about products that enable beginners to be really creative, and today’s product highlight is one I think is worth getting excited about! A few things that I really like about the shield: The shield is an add-on board that was designed to be used with the chipKIT […]
Arduino Laser Tag – Duino Tag
Duino tagger– General introduction Duino tag is a laser tag system based around the arduino. Finally a laser tag system that can be tweaked modded and hacked until you have the perfect laser tag system for office ordnance, woodland wars and suburban skirmishes. Laser tag is combat game like paintball or airsoft without the pain, […]
Wii Nunchuck Adapter
This tutorial is for all those people who have an Arduino and want to use there Wii nunchuck as an input device, but don’t really feel like cutting open the cord and ruining the nunchuck FOREVER!!!!!!!!well you’ve come to the right place! Step 1: Supplies These are the supplies you will need most can be […]
