WebDec 25, 2024 · A GPIO allows for general purpose input and output. When configured as an output the pin can actually be used for both input and output. That is, in other words, when used as a output the pin can sink current or source current. There is nothing to prevent the output from sinking current by going low. In fact this is a desirable function. WebExample GPIO Input. In this example, the inputs are normally high because the Input Common (pin 10) is connected to +5V (pin 9) An Input is activated when it is pulled low by connecting it to Ground (pin 8) Inputs can be converted to normally low by connecting the Input Common (pin 10) to Ground (pin 8).

WebMar 28, 2014 · A GPIO pin is a 'general purpose input/output' pin. This is by default only high or low (voltage levels, high being the micro controller's supply voltage, low usually being ground, or 0V). But the levels of 'high' and 'low' are usually given as voltages as a proportion of the supply voltage. So anything usually above 66% of the supply voltage ...
