How to Use Pushbuttons With Raspberry Pi GPIO Pins

WebJul 7, 2024 · General Purpose Input/Output (GPIO) pins provide a programmable interface to read the state of a binary input device (such as a pushbutton switch) or control the on/off state of a binary output device (such as an LED). You can configure GPIO pins as an input or output with either a high or low state. WebJan 17, 2024 · Q1 is an emitter follower. It's emitter voltage will be 0V when the GPIO pin is low, and 0.7V below the GPIO pin voltage when the pin is high. Assuming that the supply voltage to the microprocessor is 5V, the base of Q1 will be 4.3V when the GPIO pin is high. The base of Q2 will be at about 0.7V when Q2 is on.
