In my opinion, one of the more novel things you can do with an Arduino is put it to use as a custom game controller for your favorite games. Whether you’re retrofitting a Nerf gun, converting a rhythm controller to play an FPS game, or playing PUBG with a frying pan – using an Arduino makes it quick and easy to build your own custom controller. In this tutorial, I’m going to show you how to program your own Arduino to emulate an Xbox controller using the ArduinoXInput library.
I picked up a Novation Launchkey Mini II controller last year when I was working with those musical floppy drives, and recently I fell down the rabbit hole of Launchpad LED performance videos. That got me thinking: is it possible to control the LEDs on a Launchkey Mini like you can on a Launchpad? There’s surprisingly little information about this. Novation’s user guide for the Launchkey Mini has no mention of how to control the LEDs. There is some information available in a “programmer’s reference” manual for the Launchkey II (not the “Mini” version), but sadly the LED components don’t function the…
When the Nintendo Wii was released in 2006, there was a lot of talk about their new weird control system. In place of a typical control pad, players would use a one-handed “remote” with infrared sensors and accelerometers in place of a joystick. For those games that required additional controls, players would use an accessory controller in their off-hand. This ‘accessory’ controller is the Nunchuk. A strange, bean-shaped attachment with a joystick, two buttons, and a three-axis accelerometer. Although the Nunchuk had a lukewarm response when it was first released, it’s the perfect controller for makers who want to add some fine…
Now that all of the time circuit display electronics are in the mail it’s time to talk about programming the display. This starts with learning how to control LEDs with the Holtek HT16K33 integrated circuit (IC), which I’m using as the display’s matrix driver.
Last fall when I was working on the now-defunct ‘Footwell NeoPixels’ project I wrote a short post talking the fact that you cannot use the FastLED library with RGBW leds, and have to deal with the clunkier Adafruit NeoPixels library. Well last week, a man named Jim Bumgardner commented on that post and shared his method for doing just that: using the FastLED library with RGBW leds.
If you’re looking for a big project button, you can find it at Staples. Introduced as part of their “That Was Easy” marketing campaign in 2005, the easy button is a large red button that, when pressed, says the phrase “that was easy” via a small speaker. Its low price of $6.99 is enticing. What if instead of buying a purpose-built large button, we can repurpose an Easy Button for our projects instead?
I’ve been messing around with MIDI for my musical floppy drive project, and it was surprisingly difficult to find detailed information on how to get started with Arduino’s MIDI library. So in this post I’m going to show you, in detail, how to use this library to control anything on an Arduino using MIDI.
Since I’m experimenting with increasing Adalight framerate, the first step was to try driving the Arduino Nano with a faster serial baud rate. Unfortunately, Prismatik only supports three baud rates: 9600, 57600, and 115200. But after talking with Patrick Siegler, he pointed out a way to use your own custom baud rate for Adalight or Ardulight devices.
