A simple temperature sensor using one LM35 Precision Temperature Sensor , Humidity Sensor and Arduino, so you can hookup on your future projects. The circuit will send serial information about the temperature and humidity so you can use on your computer. I have taken data from my compost. The project is related to an existing […]
Marble Disorder is a borderline case of Marble Madness 🙂 It simulates a marble maze by sensing the box’s orientation with 2 tilt switches. Stop the press: there’s a new and more intuitive version that doesn’t require the spin knob (See video). I keep documenting the original version below for historical purposes, but don’t watch this – […]
NOTE: This Instructable is currently incomplete. I will finish it before September 19. I started this project after seeing Nick Johnson’s Turing Alarm clock. I found that the PIC chip he used was a little too advanced for me, so I decided to use the Arduino microcontroller. The original project by Nick Johnson can be […]
This instructable will show you how to make an electronic dice with minimal experience using 7 LEDs, resistors, jumper wires, and of course the arduino (or arduino clone). I wrote this instructable for anyone to easily follow along and learn more about the arduino. Questions are welcome and will be answered as soon as possible. […]
A while ago, as my first microcontroller project, I made a Pong game on a 5×7 LED display, but then nothing became of it. Recently I was given a hard hat as part of a uniform (for an engineering competition) and told to customize it, and remembered pong. In this instructable I will show you […]
In this Instructable, I will step through controlling the temperature of most kitchen appliances. As an example, I will use an old Westbend Poppery popcorn maker (aka. coffee roaster), but these same techniques will be applicable to most hot plates, coffee makers, and waffle irons. This instructable puts you at risk of electrocuting or burning […]
This Instructable will show you how to build an binary alarm clock, with a touch sensor snooze button. This is my first instructable and my first real arduino project, I hope you like it! I bought an arduino a while back and I think it’s really nice, but I haven’t really done anything useful with […]
I wanted to make an easy and secure way to enter my garage. RFID was the best way to unlock my door, even with my hands full I can unlock the door and push it open! I built a simple circuit with a basic ATMega 168 Arduino chip and a ID-20 RFID reader to control […]
This Instructable will show you how to modify an Altoids tin for a wireless 2×16 character display. Using an Altoids tin was inspired by the need to have a small yet protective enclosure for a pair of Xbee modules recently bought from Sparkfun. I purchased the Xbee Pro modules with external antenna for the extended range […]
The Just-For-Fun Sun-tracker using the Arduino and two servos. This device, along the lines of the most useless toy, is not so much for function as it is for fun. But as with many things, you can’t spell function without fun! This could easily be modified to rotate solar […]
