The 16*2-character display shows measurement values, menus, or status messages, while five buttons are used for navigation and selection. Since all buttons are read through a single analog input, the microcontroller's digital pins remain available for other functions.\u003c\/p\u003e \u003cp\u003eThe buttons generate different voltage values at the analog input, which the Arduino detects and distinguishes. The display communicates via I2C, using only two data lines. The circuit is already pre-wired on the shield, so no plugging or soldering is required.\u003c\/p\u003e \u003cp\u003eTypical applications include data loggers with live value display and control panels, controls for robotics projects with menu navigation, temperature and humidity measuring devices with calibration menus, or simple display panels in hobby electronics projects. An Arduino UNO with an attached shield and connected sensor quickly becomes a functional device for data acquisition and display.\u003c\/p\u003e \u003cp\u003eAn Arduino IDE for programming and familiarity with the Arduino environment are required, as both input channels (buttons and display) must be managed in the sketch. The shield fits only Arduino UNO and compatible boards with the same pin layout; adaptation is required for other Arduino variants or single-board computers.\u003c\/p\u003e \u003ch3\u003eSafety information\u003c\/h3\u003e \u003cp\u003eThe shield is not intended for operation in circuits with mains voltage and is designed exclusively for prototyping, testing, and development purposes. Before commissioning, check that all plugs are firmly seated and that no contacts are bent. If the circuit board is damaged or you have any doubts about its operational safety, consult a qualified electrician.\u003c\/p\u003e","brand":"Funduino","offers":[{"title":"Default Title","offer_id":65998298317149,"sku":"F23107306","price":4.55,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1074\/5649\/5965\/files\/keypad-shield-mit-1602-display-fuer-arduino-uno-funduino-6669731.png?v=1791495870","url":"https:\/\/funduino.com\/en\/products\/keypad-shield-with-1602-display-for-arduino-uno","provider":"Funduino","version":"1.0","type":"link"}
