Arduino

Part two of the DIY Arduino series. In this video, we create the PCB. Also, the project gets a new name: Pyramiduino. Watch the process to make a PCB in KiCad. And the Bald Engineer gives you a challenge, can you find the unconnected nets before he does? Check out Part 1 - the Schematic and subscribe to see when Part 3 - Turn On is posted. DIY Arduino PCB in KiCad Show Notes Pyramiduino Project on GitHub Getting to Blinky: KiCad tutorial from Conextual Electronics OSHPark- Bald Engineer’s preferred PCB supplier. (They provided the boards for free for this project.) Related Videos Part 1: Creating DIY Arduino Schematic in KiCad Part 3: Soldering and testing DIY Arduino

There is nothing more frustrating than a push button that seems to work at random. The good news is the fix is pretty simple: a resistor. It may not seem obvious when you first start working with electronics but a “floating pin” doesn’t have a defined “high” or “low” level. Remember from the Analog and Digital video, that Digital Electronics has defined voltage levels. Well, when you don’t connect anything to the I/O pin of your microcontroller, the voltage level is undefined!

When asking questions in a forum, like the Arduino forum, it is important to Post Your Code! It is so difficult to help without seeing what you intended. This was a team effort from the members of the Arduino forum. First, all of the people who help answer questions, of which, there are too many to list. The real credit goes to wildbill and Grumpy_Mike. wildbill wrote the original lyrics and Grumpy_Mike put them to music, lending his voice. I (JamesC4S) just did the video animation.

https://youtu.be/7vhvnaWUZjE Trying to decide between an Arduino or Raspberry Pi for your project? In this video we look at what the difference between the two boards are and talk about what kinds of projects each are best at. Episode Notes This one has been a long time in the making for two reasons. First, I spent some time creating an opening sequence for the videos. Thanks to everyone who helped me decide on the right music to use.

https://youtu.be/WxJKXGugfh8 We live in a world of analog. Clocks are a great example of how time is continuously changing with nearly infinite precision. However, when you look at a digital clock, there are very specific “digits”. (Get it? Digital… Digits…) Using the analogy of clocks, this TutorialCast explains the basic difference between Analog and Digital Electronics. It ends with a slight twist.
