We had a project that required connection to a digital micrometer with a data output jack. The idea was to connect a microcontroller to the micrometer, to read the measurements and make decisions based on the readings. The micrometers that we used are made by Mitutoyo, and have a funky 52 character data stream in […]
This Instructable shows you how to build a four-gang outlet box in which each outlet is controlled via an Arduino (or any other TTL level signals). It differs from the other relay boxes in that it uses no circuit boards and has very few parts (one chip and 4 relays). Step 1: Assemble Materials/Review Plan Tools […]
As you might be able to tell from recent posts, I’ve been doing quite a bit of work with an Arduino. I’ve now got at least one project that I’d like to make a little more permanent, rather than it just being a bunch of components on a breadboard. The easiest option would probably be […]
We have used the pda with a desktop computer (robot) and with the Nslu2. Here we are going to use an old pda with serial port.to act as an lcd. Everyone either has one or knows someone who has an old pda that they do not use anymore. Ask them if you can borrow it […]
Beat Sync is a single frequency audio spectrum volume meter. It can isolate around a certain frequency ( I choose the bass ) and display it on a creative 8 segment LED bar graph. This is meant to be quite simple, yet allowing room for more difficult upgrades. It is built around the Arduino Open […]
Update: I’ll add some clarifications after reading comments on various forums. It doesn’t need a 70Mhz ARM CPU, all it does is shift bits into a shift register, that’d be a total waste. There aren’t 16 CPU’s. the slices are designed to be either slave or master, just one ATMega328P chip, they’re chained together, each […]
Want to be able to control a couple of servos with a thumb-joystick? But don’t know where to start? I don’t have servos, but I can put you on the right track on how to do stuff when you move the thumbstick around. This instructable will teach you how to output the direction of the […]
Project by CU Boulder Thinks That Think students: Michelle Bourgeois, Charles Dietrich, and Ben Link Imagine having a safe in which the combo is any small object of your choosing. Perhaps it’s your favorite coffee mug, or a bat man figurine. This project is based on this idea, using the weight and placement of your […]
This is a DIY variable resistor I created as an interface for live performance– like a stomp box. I designed it as a project my audio students could build with materials we already have in the classroom. The result is a variable resistor that can be triggered with just a little pressure from hands or […]
If you touch the package, it will scream and run away–changing its course when it strikes an obstacle. When you lift the gift tag, light strikes a photocell and operation commences. Motors and a sound module are controlled by an Arduino (and Arduino Motor Shield). Major components required are: Motorized toy–Kid Galazy Morphibians Rover Remote […]
