All the images are SVG, and I didn’t have an SVG editor handy, so I used svg-edit, an online browser based editor.
Then I decided I wanted to have the pins be labeled A, B, C so that it would show up in the schematic view. So I edited the part, changed the pin wiring, and saved it as a new part. Although these pictures don’t show anode/cathode on the pins, it is visible in the tool, and I wanted to get it right. Here’s an example of a circuit using the Arduino Duemilanove and a 7 Segment Red LED 0.3″ Digital Display (RadioShack 276-075).īuilding this I was able to experiment with another feature of Fritzing, because the 7 Segment LED included in the core parts of the tool was a common anode numerical display. You can easily put bends into wires to route them in more visually appealing ways. You can work on a breadboard view or a schematic view, and they are automatically kept in sync. You drag parts off a palette and connect them up with drag and drop. So I went looking for a program that would let me document my circuits, and I found Fritzing. When I wanted to go back to an earlier circuit, I had the program saved, but I couldn’t always remember how I had wired up the circuit. I’d make something up on a breadboard, write a program for it, and then tear it apart to build another circuit. Works great, but one issue that I quickly ran into was remembering my circuits. It’s inexpensive, and there’s an open source IDE for programming. It has a small microcontroller, a USB port to connect to your computer for programming, a power socket for providing power when the USB cable isn’t connected, and various digital and analog input and output pins, for connecting up to leds, switches and various sensors. If you’re not familiar with the Arduino, it is “an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software”.
I’ve had an Arduino Duemilanove now for a couple of weeks.
