The Arduino UNO SMD board is based on the ATmega328. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with an AC-to-DC adapter or battery to get started.
IR Proximity Sensor module has the great adaptive capability of the ambient light, having a pair of an infrared transmitter and the receiver tube, the infrared emitting tube to emit a certain frequency encounters an obstacle detection direction (reflecting surface), infrared reflected the receiver tube receiving, after a comparator circuit processing, the green LED lights up, while the signal output will output digital signal (a low-level signal).
