Interface a switch to Port A bit 6 using negative logic and sketch it.
INTERFACING A SWITCH TO PORT A BIT 6 USING NEGATIVE LOGIC:
A push-button is a sort of momentary switch that, when pressed, completes a circuit and, when released, returns to its original position, breaking or interrupting the circuit.
The switch is an information gadget. When interfaced with microcontroller, it tends to be utilized to control different peripherals associated with the microcontroller. It essentially "makes" the electrical circuit by building up the progression of flow. Or on the other hand "breaks" it by intruding on the progression of current.
A switch, when not being used, has no distinct worth related with it. Correspondingly, the pin of the uC that it is joined to has no conclusive worth by the same token. It is supposed to be skimming between 0 or 1. Subsequently a resistor is associated between the switch and or GND. To appoint a particular worth to it for the last time.
