Latest Sensor Shield V5.0 sensor expansion boardStill only uses stack design , the motherboard will not only UnoAll digital and analog interfaces to extend out of the steering line order form , but also ad hoc IIC interface ,Servo Controller Interface,Bluetooth ModuleA communication interface , SD card interface module in communication ,APC220 RF ModuleA communication interface ,Ultrasonic sensorsInterface ,12864 LCDSerial and parallel interfaces , independent expansion out more convenient to use . For beginners , not for the cumbersome and complex circuit connection and a headache , will simplify this circuit sensor expansion board in the true sense , can easily be used to connect the sensor , a sensor requires only a common 3P sensor cable ( regardless of digital cable and analog cable ) , after the completion of the circuit connection , write the corresponding program to the controllerRead the sensor data, or receive wireless module return data , through arithmetic processing , and ultimately easy to complete your own interactive works .
