Tutorial 14 for Arduino: Holiday Lights and Sounds
This is one that I’ve been excited about for a long time. When element14 asked me to put together a holiday special, I knew just what to do. This episode is the most technically complex so far; it covers non-inverting op-amp circuits, low-pass envelope detection filters, buffers, power management, and[…]
Arduino Tutorial Series
I produced a series of widely viewed Arduino Tutorials sponsored by element14. These videos have been viewed many millions of times.
Review: WickedDevices Arduino LCD Shield
It’s LCD mania! Following my review of the Lumex 16×2 Character LCD from element14 and my recent tutorial on interfacing an Arduino with an LCD display, I have one more LCD-related post up my sleeve. WickedDevice, a small open source hardware company based in Ithaca, NY, sent me their LCD[…]
Tutorial 13 for Arduino: Liquid Crystal Displays
I had initially planned to do an LCD tutorial a little further down the line, but there was very high demand for it, and I already had a circuit assembled for testing the new LCD that element14 sent me to evaluate. So, this seemed like an appropriate time to roll[…]
Tutorial 12 for Arduino: RFID Card Reading
Finally! It’s been about 3 months since my last arduino tutorial – I’ve been keeping busy as usual. I’ve been working on this one for some time. I got the parts months ago, made an outline a few weeks ago, prototyped the circuits and wrote the code last week, and[…]
Audacious Arduino Arguments on the Amp Hour
I’m a long-time fan of the Amp Hour Podcast, hosted by Chris Gammell and Dave Jones. This week, Jeff Keyzer and I were invited to guest host with them! This was an Arduino-centric episode (I’m not sure if that was my fault at all…), but we also discussed engineers working[…]
Tutorial 11 for Arduino: SD Cards and Datalogging
This is my first in a series of more advanced Arduino tutorials. Now that we’ve covered the basics in tutorials 1-10 (you have watched them all right!?), it’s time to start pursuing some more complex projects! In this episode, we’ll utilize an SD card shield from cooking-hacks.com to create a[…]
Tutorial 10 for Arduino: Interrupts + Debouncing
This video was featured on Hackaday.com on 3/8/2011 This tutorial was featured on the official Arduino blog on 3/9/2011 Interrupts are an extremely useful, yet often feared element of microprocessors. Interrupts allow you to run a program, while still being able to react to asynchronous input from the outside world. On[…]
Tutorial 9 for Arduino: Wireless Communication
This tutorial was featured on the official Arduino blog on 3/9/2011 This week, we go wireless! We’ll be using a set of arduino Unos, XBee shields, and XBee Transceivers that will create a Personal Area Network (PAN) for wireless serial communication. By the end of the episode, we will be[…]
Tutorial 8 for Arduino: SPI Interfaces
This tutorial was featured on the official Arduino blog on 3/9/2011 In this week’s arduino tutorial, we’ll be taking a look at SPI device control using the arduino. Specifically, we’re going to be using the Analog Devices 5204 Digital Potentiometer to control the brightness of several LEDs. Enjoy the video![…]
