TM1637 4-Digit Display + IR Proximity Sensor

The TM1637 4 digit LED Display Module is a low-cost solution for displayingArduinoproject output data. Though the data displayed is limited to numbers, users can also display characters such as A, B, C, and so on. The TM1637 Driver Chip controls the 4 digits on this 7 segment LED display. This TM1637 4 Bits Digital Tube LED Display Module can be controlled with just two wires.

IR Proximity Sensor

The IR Proximity Sensor module has great adaptive capability of the ambient light, having a pair of infrared transmitter and the receiver tube, the infrared emitting tube to emit a certain frequency, encounters an obstacle detection direction (reflecting surface), infrared reflected back to 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), through the potentiometer knob to adjust the detection distance, the effective distance range 2 ~ 30cm working voltage of 3.3V-5V.
