Arduino 3.3V

This Lazy Old Geek (L.O.G.) loves Arduinos. I have noticed that a lot of sensors, like GPS, LCDs, magnetometers are 3.3Vdc sensors. But the standard Arduinos, Uno, RBBB are 5Vdc modules. So I decided I’m going to make more of my Arduino projects with 3.3Vdc AtMega328s. Now I’ve done this before but will go through some of the problems. PROBLEM: The standard Arduino uses a 16MHz crystal. Now if you look at t ...

Arduino passive IR trigger for Canon EOS

The other day I wanted to experiment with external triggers for my Canon EOS 550D camera. I stumpled upon a nice open source project called Arduino Camera Control from Oleg Mazurov, the creator of the USB Host Shield library for Arduino. The Arduino Camera Control project depends on the USB Host Shield library and the USB Host Shield from Sparkfun. It supports Canon EOS and Powershot, as well as Nikon DSLRs ...

How to Install the Arduino to the Lithium Backpack using arduino

The Arduino is an open source hardware input and output circuit and the Lithium Backpack is a Ardino accessory that will power the Arduino when it is away from a computer or a wall power. These products are sold at Liquidware for under $34 each. Step 1: Plug in the battery connector to the board. The black wire should face the outside (away from the battery). Step 2: Plug the Ground pin in with 22-24 gauge ...

Use Arduino to Interface with a Remote Controlled Power Switch

Update: check out the RFToy — an easy-to-use standalone gadget to control remote power sockets. Also, support for remote power sockets have been added to OpenSprinkler firmware 2.1.1. For a while I’ve been looking for a way to switch household power line (110V) devices. One of the simplest options is to use a relay that is connected to the power line. This is easy in concept but quite dangerous to work with ...

Using the Arduino Serial Port

The Arduino Uno can send data (such as a text message) to the PC over the USB cable. The Arduino IDE has a serial monitor window that can be opened and will receive and display the data sent from the Arduino board. Data can also be sent to the Arduino board from the serial monitor. This serial communication is very useful for controlling electronics that is connected to (interfaced to) the Arduino board fro ...
