This LCD shield can apparently meet your needs to display much information. It can display English, Chinese, even images. It also integrates a 5 DOF joystick. The shield has 6 Digital IO and 5 Analog IO. This 3 pin connector has a temperature sensor which can help indicate the temperature.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eUltrasonic Module HC-SR04 Distance Sensor\u003c\/strong\u003e are 4 pins : VCC , Trig, Echo, GND . So it's a very easy interface for controller to use it ranging. The all process is: pull the Trig pin to high level for more than 10us impulse, the module start ranging;finish ranging. If you find an object in front , Echo pin will be high level , and based on the different distance, it will take the different duration of high level. So we can calculated the distance easily :\u003cbr\u003eDistance = ((Duration of high level)*(Sonic :340m\/s))\/2\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003ePackage Content:\u003c\/strong\u003e\u003cbr\u003e\u003cem\u003e1 SainSmart LCD4884 Shield\u003c\/em\u003e\u003cbr\u003e\u003cem\u003e1 SainSmart HC-SR04 Distance Sensor\u003c\/em\u003e\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"SainSmart","offers":[{"title":"Default Title","offer_id":49290312810650,"sku":"20-011-C24","price":9.8,"currency_code":"GBP","in_stock":true}],"url":"https:\/\/coretarps.co.uk\/products\/hc-sr04-ultrasonic-distance-sensor-sainsmart-graphic-lcd4884-shield","provider":"My Store","version":"1.0","type":"link"}
