Keeping on registering data from different sensors my next project has been the all-time favourite weather station. This time I wanted to build an 100% autonomous outdoor sensor.
To achieve this goal I started playing with a LiPo battery and a solar panel. The Arduino Fiolooked like the perfect out-of-the-box platform to be the center of the project. It’s a ATmega328P (the same micro as the UNO), has a connection for a LiPo battery, a charge circuit based on the MAX1555 (with an USB connector) and a socket for an XBee radio module. So I just really had to wire things up and work on the code to reduce the power consumption to its minimum.
MAKE's just-released Vol. 36 delves into the world of boards and includes a detailed photo illustration of the evolution of Arduino. Pick up a copy of the magazine to see if for yourself of download it here.
One of the first examples of coding on the Arduino Robot is called “LOGO” which is very similar to an early educational programming language that controlled a virtual turtle moving across the screen with simple instructions. This time however, instead of having a small virtual turtle running on a screen, we have a robot that can respond to commands demonstrating a basic example of movement.
This second sensor project uses the IR Fire Sensor. It has two outputs, 1 digital, 1 analog. I'm using the digital output (sensitivity set with onboard trimmer pot) to set the Pin 13 LED, to show flicker.
An Arduino is by no means expensive, but that still doesn't mean that it suits your needs right out of the box. If you want to make your own custom board, Make shows you how in a three-part series. Read more...
Have you ever wondered what's inside a Mac's Magsafe connector? What controls the light? How does the Mac know what kind of charger it is? This article looks inside the Magsafe connector and answers those questions.
