WebOct 3, 2016 · If you want a button or switch as an input on a microcontroller (MCU), you can use a “pullup resistor” so that the input is seen as a logical high when the (normally open) switch or button is closed. A pullup resistor is connected to Vcc, or logical high for your input, and therefore “pulls up” the value on the pin to high. WebAug 9, 2024 · The MCU is then placed into sleep mode and configured to wake up if the edge interrupt is flagged. Pressing the button then “turns on” the system by waking up the MCU. One can go further by placing a p-channel mosfet in series with the rest of the circuit load that the MCU can control to further save on power while the MCU is in sleep mode.
