The SainSmart Uno for Arduino contains everything needed to support the microcontroller.The Uno features the Atmega8U2 programmed as a USB-to-serial converter and has a resistor pulling the 8U2 HWB line to ground, making it easier to put into DFU mode.

The 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.

The SainSmart Prototype Shield is a great kit to new Arduino users and geeks who have sparkling ideas. You can choose to do soldering in the soldering area. You can also make good use of the mini breadboard which can save your time of soldering. Try any circuit you want to the Arduino. You also can choose to use your own breadboard.

The 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
