Hello all! In this Instructable I’ll be showing you how to make a robot similar to the “Mobile Arduino Experimental Platform” (MAEP) that I made. It is equipped with two motors that can steer the robot and the ability to see obstacles in front of it with a PING))) ultrasonic sensor. With the attached breadboard, […]

My friend Jonathan Ward and the rest of the team at Otherfab have posted their new CNC milling machine, the Othermill, to KickStarter. This is a robust, low-cost machine for milling circuit boards, wax molds, wood, aluminum and more. The machine is made from high density polyethylene with an ingenious snap-fit mechanism that’s strong, reversible, […]

I’m teaching “Electronics for Scientists” this semester, and I wanted to allow each student to have their own Arduino to play with for microcontroller lab exercises and possibly use for their final projects. The Arduino is not very expensive at roughly $30 per, but they add up quickly when you have a whole class of […]

An RGB LED and 3-axis accelerometer enable thousands of applications without requiring any modifications. Create a motion alarm to warn you if someone moves your bike. Get wireless notifications for text messages, emails, and Facebook posts. Build an iPhone-controlled Nerf gun turret. The possibilities are endless. Want even more applications? Pre-Order four Cortados and get […]

Introduction “The sound and experience of drums… Any time, anywhere, with any object.” -Project Soundbyte It’s Friday night and you’re hanging with your friends at home. There are no parties tonight and you have seen everything on Netflix already – you’re bored out of your minds. One of your friends pulls out his portable roll […]

Fijibot is an autonomous, self-charging photovore. I built him using a 1.5 liter Fiji Water bottle, an Arduino Uno, 6v solar panel (plus various other parts) from Radio Shack, an Arduino Proto Shield (plus various other parts) from Adafruit, and the wheels and steering arrangement from an RC car. I decided to use a Fiji […]

This is something that almost every maker that is interested in easy electronics should know how to do. It is great for decorating or just experimenting for starters. I am doing this tutorial because I had bought an RGB display from the Maker Shed and it was hard to track down the instructions. First I […]

I run a NFS/NIS network under a combination of OS’s for the upper-division physics lab here at CSUC, and one source of irritation is when one machine goes down and nobody lets me know until suddenly that machine is absolutely necessary NOW! So I figured an Arduino, living in the machine on my desk, might […]

Moving on from the last chapter where we explained an 8-bit ADC, in this instalment we have the Texas Instruments ADS1110 – an incredibly tiny but useful 16-bit analogue-to-digital converter IC.  It can operate between 2.7 and 5.5 V so it’s also fine for Arduino Due and other lower-voltage development boards. This is a quick guide […]

Introduction For our final project, we have decided to use the microcontroller provided to make a device which would measure body fat percentage of one’s body. The basic principle behind this project is known as bioelectrical impedance analysis. This technique uses a small alternating current flowing between two electrodes attached to skin surface to determine […]
