For British kids of a certain age, their first experience of a computer was very likely to have been in front of a Sinclair ZX81. The lesser-known predecessor to the wildly-successful ZX Spectrum, it came in at under £100 and sported a Z80 processor and a whopping 1k of memory. In the long tradition of …

Hi, all! Today I’ m trying to explain you my last project: “The morse code generator by a PS\2 keyboard” I’ ve used an PS/2 keyboard to send input to my Arduino board (like described in here) and transform it in morse code that activate a speaker and a relay. Components: – PS\2 keyboard – …

In this project we are going to be making something super useful! It is a wireless keyboard that you can connect to your PC and assign each button any shortcut or key sequence you want! I have made it in a way where you can customise the keyboard to meet your exact needs, for example, …
Every now and then you might be interested to input text to your arduino project. You can do it using Serial input but this would require Arduino to be always connected to a computer. In this tutorial I would show you how to implement text input using the small OLED display and 5 key keyboard …
For this Instructable, I have made a primitive musical soundboard using an ultra sensor as a keyboard. Here I will show you the basic steps on how to create such a device yourself. Later on, in December, I will demonstrate to you how to make a more complex or soldered version of this soundboard with …

A common problem that often comes up when working with micro controllers, is running out of IO for all the input the projects requires. So I came up with this solution that allows a user to have up to 4096 button inputs using only 4 lines of IO. This is done by sending out data …
This is a keystroke injection device (also called badusb). It is similar to a well-known USB rubber ducky made by hak5, but has much extended functionality, lower price and is also completely open source. It looks and feels like an ordinary USB flash drive, but acts as a keyboard that types in a preprogrammed payload. This payload …
When it comes to rendering text input into an electronic form,the newest keyboards use USB for wired interfacing, while the oldest Morse keys use a single conductor. Shall the two ever meet? For [Matthew Sparks] the answer is yes, with his “The Gadget” Morse-to-USB HID interface which presents a Morse key to a computer as …

If you’ve been to a bar sometime since the 1930s, you’ve probably spied someone drinking a Tequila Sunrise. It’s a drink that mimics the beautiful colors of the dawn. In much the same way, so does this Sunriser keyboard build from [crashl1445]. Built for a high-school engineering project, the build looks resplendent with its yellow case, …
Trust me, you don’t have to build your own keyboard from the deskpad up to be happy or feel like one of the cool kids. Sure, it doesn’t hurt, but not everyone is able to or even wants to start from next to nothing. Take [Roger] for example. [Roger] started with a stock mechanical keeb …
When the button is pressed in this example, a text string is sent to the computer as keyboard input. The string reports the number of times the button has been pressed. Once you have the Leonardo programmed and wired up, open up your favourite text editor to see the results. NB: When you use the …
