I created a wireless mechanical keyboard using an arduino and BLE. I love the feel of a mechanical keyboard but I hate the wires. So I made it wireless.
This was a great project because I had never used bluetooth or BLE before. Nor had I used the PS2 protocol. It was a fun little project. Now I have very clean looking desk.
Gamers may freak out because this is a slap in the face for low latency. However, I am coder. As long as my eyes can’t tell then I don’t care. I just want a professional looking, nice feeling keyboard for coding and a wireless WASD fits that description.
Adafruit Bluefruit LE Micro – Bluetooth Low Energy + ATmega32u4: Would you like to add powerful and easy-to-use Bluetooth Low Energy to your robot, art or other electronics project? Heck yeah! With BLE now included in modern smart phones and tablets, its fun to add wireless connectivity. So what you really need is the new Adafruit Bluefruit LE Micro – it’s an Atmega32u4 chip (same as used as in the Adafruit Flora or Arduino Leonardo) plus our SPI Bluefruit LE Friend in one.

Adafruit Pro Trinket LiIon/LiPoly Backpack Add-On: If you have a Pro Trinket you probably know it’s the perfect little size for a portable project. This LiPoly backpack makes it really easy to do! Instead of wiring 2 or 3 boards together to make a charging system, this little PCB sits on top of the Pro Trinket and allows a LiPoly/LiIon battery to plug in. When the Pro Trinket USB port is powered, the battery is recharged automatically. Unplug the USB port and the Pro Trinket will switch over to the rechargeable battery. Read more.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
