ESP8266 ultrasonic distance measuring Displayed on MAX7219 Dot Matrix

ESP8266 ultrasonic distance measuring Displayed on MAX7219 Dot Matrix

In this Arduino Tutorial we will learn how the HC-SR04 Ultrasonic Sensor works and how to use it with the Arduino Board. You can watch the following video or read the written tutorial below.

The HC-SR04 Ultrasonic Module has 4 pins, Ground, VCC, Trig and Echo. The Ground and the VCC pins of the module needs to be connected to the Ground and the 5 volts pins on the Arduino Board respectively and the trig and echo pins to any Digital I/O pin on the esp8266
