Control Servo motors with Nextion HMI – Part 1
Over the last weeks, I got several mails from readers asking about the use of servo motors (or short, servos) together with Nextion HMI. The ones wanted to control a few servos directly from the Nextion's (Enhanced and Intelligent series) GPIO, others suggested to extend the Nextion Mega I/O project to allow controlling servos. The scientific approach is to gather information before taking a decision or even starting a development, thus, let's look at how servos work and how they are controlled, first. And then, let's see how the Nextion HMI can be used for that.
