![]() ![]() We’ve had a decent introductory ‘quick start.’ Let’s drill deeper and see what else we can do. GETTING BETTER ACQUAINTED WITH FRITZINGįritzing is a too-cool tool. To be a compliant shield, you need the PCB to fit on an Arduino - thus, the rows of holes on the top and bottom to fit over the Arduino connectors. Remember, though, that the purpose of all this is to introduce Fritzing and how to use it to design an Arduino shield. That seems to leave a lot of wasted board space, and indeed when I designed (not using Fritzing) a nearly identical circuit, I made the board much smaller. The RTC part of the design is fairly small and tucked away in the bottom left corner to be near the Arduino pins needed to provide power and the I 2C connections required by the DS1307 chip. The PCB is shown front and back in Figures 4 and 5. Plus, they sent me an extra board for free - a two for one hidden sale that you might (or might not) get!įIGURE 1. I purchased one PCB for $26.27 and received it three weeks later (really not bad at all). THE PCB FINALLY ARRIVES!įigures 1, 2, and 3 show the Fritzing breadboard, the schematic, and the PCB views, respectively, that were used to generate the Gerber files that I sent to BatchPCB. Well, after three weeks the PCB arrived and it works! Let’s take a look at it and then go a bit further with Fritzing to start learning how to make parts. We also saw how to take that schematic and create a printed circuit board (PCB) design that we sent off to BatchPCB. We saw how to use Fritzing to take the breadboard design from Part 1 and turn it into a schematic drawing that is crucial for understanding and documenting a design. In our last episode, we continued learning about Fritzing - a novice-friendly electronics hardware design package that we are using to design a real time clock (RTC) shield for an Arduino.
