In the DigitallnputPullup program, there is a relational operator ==, which is not the same as the assignment operator =, and the double equal sign is an operation used in the expression of the if statement to determine whether the expression can be true. The single equal sign is used ...
The remote operator can control the flow of water and the fire extinguisher pump. On the other hand, the robot’s movements can be monitored by the remote operator using a camera connected to a smartphone. The required components for implementing this project are listed in Fig. 8.7. Sign in...

In this tutorial we will analyze how to use the C++ conditional operator, also known as the ternary operator, on the Arduino core running both on the ESP32 and on the ESP8266.
