[Discontinued] SainSmart LCD 4884 Shield + HC-SR04 Kit for Arduino Due UNO Mega2560 R3

SainSmart LCD4884 Shield provides 48x48 display. 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.

Ultrasonic Module HC-SR04 Distance Sensor 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 :
Distance = ((Duration of high level)*(Sonic :340m/s))/2
