# esp-distance-sensor

Ultrasonic distance sensor (HC-SR04) and 4-digit 7-segment LED display (TM1637) on a Wemos D1 mini.

Install the following Arduino libraries:

- [HCSR04](https://github.com/Martinsos/arduino-lib-hc-sr04)

- [TM1637TinyDisplay](https://github.com/jasonacox/TM1637TinyDisplay)

Connect jumper wires on mini breadboard (both on 5V):

- HC-SR04: TRIG = D2, ECHO = D1

- TM1637: CLK = D5, DIO = D6
