An Arduino shield is basically another circuit board that plugs into the Arduino and extends its capabilities in some way. So, of course, if you create your own DIY Arduino, you have to create a DIY Arduino shield. I needed a way to attach an HD44780 LCD to my DIY Arduino so I created a …

I just got a good deal on several PIC18F4550 chips. So, I decided to make a Do-It-Yourself Pinguino PIC18F4550 Board to test them out. The Pinguino boards are based on the same concept as an Arduino. However, instead of Atmel chips, Microchip PIC® chips are used. All of the Pinguino boards use PIC® chips with …

[/warning] I built a dual circuit so that two things can be controlled from one board. Here is the fritzing graphic: Once built, …

Shown below is one of my DIY Arduino circuits. The circuit does not have the FTDI chip built in. The FTDI circuit is only needed for programming and cutting out un-necessary components saves a bit of money. The ICSP connection (6 pins comming out the side) on …
