This is the 5th lesson of the Arduino UNO R4 Minima Ultimate Training Series. In this video, Joed Goh talks about how to read digital signals from Arduino UNO's digital pin. He explains how to properly implement a pull-up and a pull-down resistor and what ideal resistor value should be used when using push-button switches. He also discusses the use of if...else... conditional statements to perform decision making in your code.
