This touch button project has a very simple premise, take a button, make it show up as a keyboard or mouse, and add some sweet lights to it. It’s not going to make your jaw hit the floor in awe but there are a ton of novel uses for a device such as this. The lights on the front of the button allow the computer to provide feedback to the user so some combinations of button presses and light flashes can be used to do more complex things then just pressing the button once and having the computer do one thing in response.
A capacitive touch sensor is used to detect a button press. This sensor has a maximum sensing range of 2cm / 0.79″ meaning you can mount this button behind glass, plastic or wood. The button is configurable using any text editor on any computer, it can be configured as a keyboard or as a mouse click. This is the perfect gizmo for interactive art installations!
Configuration takes place using the two tactile buttons on the back as inputs, and connected to a computer as a keyboard for the output. Menu items are printed in a text editor. It’s a rather novel method shown well in the video below.
