Arduino Experimentation Kit

ARDX

[Oomlout] has created an Arduino Experimentation Kit that uses basic sensors, buttons, and LEDs to teach electronics and programming. Printed overlays are secured on a breadboard, indicating components and connections. The Arduino is then used to drive the circuit. Examples include driving motors, using shift registers, and making beeps with a piezo element. These are backed up by explanations and code. The breadboarding kit is very similar to the classic 300-in-1 project kits marketed to beginners. In addition, all of the materials are released as open source. Kits are also available that include everything needed to create the circuits.

4 Or More Servos On An Arduino

February 23, 2009 by Caleb Kraft 17 Comments

roboduino

The latest version of the Arduino software allows you to use more than two servos at a time. Curious Inventor has posted a demo showing how to run 4 servos from a keyboard input. The code should also work just fine on Arduino clones, like the Roboduino pictured above. They point out that if you are running version 12 of the software, some manual additions will be necessary.

If you are interested in trying out some home automation, but don’t want to get into the potentially dangerous area of hacking your house wiring, consider these servo switches. These allow you to flip a switch, using a servo. They are clean, temporary, and fairly compact. You can purchase them at oomlout.com or download the designs and build your own.

Automated Wire Cutter And Stripper

witecutter

Kit builder oomlout—we’ve featured their servo bot—needed to produce a lot of precut wires. After cutting and stripping more than their fair share, they decided to apply some heavy engineering to make things easier. They constructed a machine to do the job for them. It has three main components: a servo driven wire feeder to measure the length, a two servo wire stripper that uses an exacto blade, and finally a wire cutter made from snips and a drill motor. The machine is controlled using an Arduino. They’ve published all the plans and code to Thingiverse incase anyone else wants to build a similar machine for their own kit shop. A video of the machine is embedded below.

USB Servo Squirter

squirt

Here is a great project for learning how to control servos. They’ve made a USB controlled squirt gun using the USB NerdKit, a pump and a servo. This is a great tutorial to learn about PWM and controlling servos. The tutorial is very thorough, with great pictures and a video of it all , which you can see after the break.

Machining Custom Robot Parts

cncrobotparts

Robot Magazine has a great article about how to machine custom robot parts. In this article [Matt Bauer] shows the basics of making custom robot parts and skeletal brackets for his humanoid robot creations using a CNC mini-mill. He uses a custom jig overlay designed to make cutting thin sheet stock much easier and to protect his equipment. This template concept creates a platform for many other custom parts going forward. [Matt] includes the .nc g-code files as well as a “how-to” PDF in a ZIP file.

Simple Laser Projector

laserscanner

[kap4001] built what has to be the simplest laser scanner possible. It’s two servos strapped together with zip ties plus a 5V laser module. They’re connected to a Pololu serial servo controller. The laser is pulsed by switching the DTR line. You could use it to draw images like the one above… except that’s an 85 second exposure.
