Connect the centre pin to your gpio input, and the other two outer. If you are talking about an input 1 or 0. Gpio (general purpose input/output) is the foundation of embedded system i/o
What is GPIO Pull up & Pull down in ESP32? - YouTube
Understanding gpio configuration is essential for.
This chapter lays the groundwork, explaining the basic concepts of digital input/output, pin configuration options like pull.
In this tutorial, we'll explore the various input modes available on stm32 microcontrollers, how to configure them, and when to use each. This application note provides basic information about gpio configurations as well as guidelines for hardware and software developers. What is gpio and how does it work internally So you could just use that if the current is acceptable
But it looks like you could use an external. But while configuring a gpio pin which will be connected to an led, what is the use of these settings 一般来说，需要区分这个GPIO口用于输入还是输出。 如果是output，那个一般选择no pull,这样，引脚才能根据你的output数. Below is the pin in question
What do you mean is the voltage just processed
