Project 17 - Shift Register 8-Bit Binary Counter
I enjoyed this project... for the first time in a long time, I finally understand how this type of chip works. I've encountered it before in other circuits, but there's never really been a good...

Project 18 - Dual 8-Bit Binary Counters
Looks like I'll be paying a visit to my local electronics store on Monday... I believe that one of my 595 chips is damaged. Let me explain.I wired up the circuit as shown in Figure 6-4... it's a fairly...

Project 19 - LED dot Matrix Display - Part 1
I'm quickly learning that when you work with electronics it's best to do so when your frustration level is low...Thankfully, when I opened up my new box of goodies from SparkFun (who, once again,...

Project 19 - LED dot Matrix Display - Part 2
I ended up using a set of headers to raise the 8x8 display about .5cm off the breadboard... it was just enough to allow me to use my jumper wires (the non-flexible ones).My next task was to upload the...

Project 20 - LED Dot Matrix Display - Scrolling Sprite
Well, I feel much better today - I was able to rule out my wiring, chips, and 8x8 display as the problem. I was reading ahead into Project 20 that uses the same wiring setup as Project 19. I took a...

Project 21 - LED Dot Matrix Display - Scrolling Message
In the continuing story of 8x8 LED displays not working for me, Project 21 is no different. I've checked, double-checked, and triple-checked my wiring and can find nothing wrong with it.I'm using the...
View ArticleProject 21 - LED Dot Matrix Display - Scrolling Message FIXED
This project's been driving me crazy... the code makes total sense and I couldn't find any errors with my wiring. So I just knew it had to be a bad chip or a bad 8x8 display... because there's simply...

Project 22 - LED Dot Matrix Display - Pong Game
After downloading the LedControl library and extracting it into the Arduino library folder, I uploaded the very simple program for project 22 to my Arduino. The only modification I made to the circuit...

Project 25 - Servo Control
Project 25 was fairly easy to wire up and the code is extremely easy to follow. I'm really beginning to appreciate libraries... they make programming the Arduino so much easier. Calling functions by...

Project 27 - Joystick Servo Control
I purchased two of the COM-09032 joysticks from Sparkfun for Project 27... they were only $4.00 each and looked like they'd be fun for a future project so I grabbed them. (I just hope they work -...

Project 27 - Joystick Servo Control Part 2
It didn't take me that long to solder the six wires to the joystick, so I went ahead and plugged it in to the circuit I made in Project 26... pushing the joystick forward or backward causes one of the...
