[Discontinued] SainSmart LCD 4884 Shield + HC-SR04 Kit for Arduino Due UNO Mega2560 R3
SainSmart LCD4884 Shield provides 48×48 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
