Got Wireless? Modify a Simple 12VDC Wireless Remote Control for 5VDC Operation

Got Wireless? Modify a Simple 12VDC Wireless Remote Control for 5VDC Operation

Adding a remote control switch to nearly any project is easy with these small keyfob-based RC relays. They are very inexpensive (<$20) and offer such options as MOMENTARY and TOGGLE operation as well as multiple relay channels to control. However, from what I found, these units require 12VDC to operate properly. This article explains how […]

Using an Arduino to Process Fire Dept. Tones

Using an Arduino to Process Fire Dept. Tones

I’m on the volunteer fire dept. in my town and as such, like to keep tabs on when neighboring towns are dispatched. I came up with the idea to make a large map of my area and put an LED in each town that would light up when they get called out. To do this […]

XBee Pulse I/O Single Port Assembly Instructions

XBee Pulse I/O Single Port Assembly Instructions

In this project we’re going to assemble the XBee Pulse I/O Printed Circuit Board — an open-source hardware design which can be used to automate things wirelessly. This hardware is used in the “12,000-mile Universal Remote” project from Make Vol. 30.

Sun Logger

Sun Logger

A data logger is a device that is left to run for long periods of time, making regular measurements of external sensors. We’ll be using the Arduino microcontroller and a homemade “shield” (an Arduino accessory board) to create a device that gathers data on light-brightness in an area and how it changes over time.
