Filear.com posted a cool hack that can be done in an afternoon if you have the parts handy. The author built a DIY oscilloscope using an Arduino Pro Mini and the LCD from a Nokia 3310. The Arduino is wired up to sample from an ADC port and writes those values to the screen to create a waveform. Two potentiometers control the sampling speed and input voltage for approximate time and amplitude scaling just like the real thing.
Our friends over at Make magazine put together some awesome projects, and this is one of our favorites. Last year, hacker extraordinaire Matt Richardson released this Arduino project that will monitor your TV closed caption signal for a list of keywords and mute the television when it finds a match. From his description on Make’s site:
I don’t know about you, but I’m a little sick of hearing about the same people on TV over and over again. I came up with this Arduino-based solution to mute my TV so that I don’t have to hear about Donald Trump’s feud with whomever or Charlie Sheen’s most recent rant.
Does your program seem like it’s trying to do too much at once? Are you using a lot of
while() loops that are holding other things up? If so, your project is a good candidate to use timers. In this tutorial, we’ll discuss AVR and Arduino timers and how to use them to write better code.
When you start programming AVRs, you already have your hands full with learning the C language, I/O registers on your chip, and how to manipulate the hardware. However, you also have to worry about your development environment. Figuring out how to compile code, get it on your device, and debug it can seem overwhelming when you’re trying to tackle one thing at a time.
Pete Brown, the lead of the Developer Guidance Community Team at Microsoft, has written a great post on how to properly prepare for a new AVR project. He covers how to choose a microcontroller, collecting necessary datasheets and information, setting up your hardware development environment and software IDE, and how to properly test and debug your code.
If you’re looking to make the jump from Arduino or another processor family but aren’t sure where to start, this should help get you off the ground. You can also cross-reference our tutorial on using AVR Studio 5 with Arduino projects if you want to mix and match environments.
At long last, the Arduino team has released Arduino 1.0 – an update to the development environment and core libraries that make the Arduino hardware do its thang. The 1.0 update has been in the works for a while, and covers a lot of changes, including some you’ll notice and some you won’t. How does all this affect your Arduino projects? Read on to find out.
Like hacking? Like cars? At EngBlaze, we’re pretty fond of both of these things, which is why we enjoy seeing creative ways to hack your vehicle. The following projects are a few ideas if you’re looking to insert some DIY hardware into your ride (or perform surgery on an unsuspecting friend’s). Here are five of our favorite ways to hack your ride and make it stand out from the crowd.
