We found an easy to use PS\/2 track-pad that is easy to use and interface with. This track-pad is two-in-one: you can use it either in relative 'mouse mode', where it spit out finger movements as they change OR you can put it into 'tablet mode', where it give the absolute X and Y location of the point being touched. It will also return Z coordinates for how hard the user is pressing and a flag if a finger is touching the pad or if the finger was removed (so you know its no longer being touched). This device does not support multitouch, but it does have basic gesture support for 'tap' and 'double tap' on the touch-pad area. There's also two tactile buttons that act like a the two buttons on a mouse.\u003cbr\u003e\n\n\u003cbr\u003e\n\nWe thought this would make a great interface, such as for a lighting controller, music devices, or for drawing shapes.

We like this small and easy to use mag-stripe reader for being so microcontroller-friendly. Instead of a USB port, it has a PS\/2 interface and acts like a 'keyboard'. In fact, its designed to be a 'pass through'\/'keyboard wedge' device for point-of-sale terminals.

You'll need to solder the header onto the PCB to use with a solderless breadboard. but it's fairly easy and takes only a few minutes even for a beginner.\u003c\/p\u003e\n\u003ch2\u003eTechnical Details\u003c\/h2\u003e\n\u003cdiv id=\"tab-technical-details-content\" class=\"panel-collapse collapse in\"\u003e\n\u003cdiv class=\"row\"\u003e\n\u003cdiv class=\"col-lg-12 col-md-12 col-sm-12 col-xs-12\"\u003e\n\u003cul\u003e\n\u003cli\u003eProduct Dimensions: 25.4mm x 17.6mm x 4.6mm \/ 1.0\" x 0.7\" x 0.2\"\u003c\/li\u003e\n\u003cli\u003eProduct Weight: 1.6g \/ 0.1oz\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cul id=\"product-files\"\u003e\u003c\/ul\u003e\n\u003cdiv class=\"row\"\u003e\n\u003cdiv class=\"col-lg-2 col-md-3 col-sm-3 col-xs-4\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"col-lg-2 col-md-3 col-sm-3 col-xs-4\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":49567740330211,"sku":"gfo1787258324719","price":3.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0734\/2961\/4819\/files\/adafruit-mcp9808-high-accuracy-i2c-temperature-sensor-breakout_1.jpg?v=1787258329"},{"product_id":"sparkfun-qwiic-ultrasonic-distance-sensor-hc-sr04","title":"SparkFun Qwiic Ultrasonic Distance Sensor - HC-SR04","description":"\u003cdiv id=\"description-tab\" class=\"tab-pane fade\" role=\"tabpanel\"\u003e\n\u003cdiv class=\"col-sm-12\"\u003e\n\u003cp\u003eYou may be familiar with the classic HC-SR04 distance sensor, it is great for providing non-contact distance readings from 2cm to 400cm.
