Common Mistakes

Confusing pull-up with pull-down resistor.

A pull-up resistor connects the input pin to VCC to ensure a default high state.

Common Mistakes

Confusing pull-down with pull-up resistor.

A pull-down resistor connects the input pin to ground to ensure a default low state.

hard

Fix the error in the statement about resistor function.

PCB Design

A pull-up resistor ensures the input pin is [1] when not driven.

💡 Hint

Common Mistakes

Choosing 'low' or 'floating' instead of 'high'.

Pull-up resistors ensure the input pin reads high when no other signal drives it.

4fill in blank

hard

Fill both blanks to complete the description of pull resistors.

PCB Design

A pull-up resistor connects the input to [1], while a pull-down resistor connects it to [2].

💡 Hint

Common Mistakes

Mixing up VCC and GND connections.

Pull-up resistors connect to VCC (positive voltage), pull-down resistors connect to GND (ground).

5fill in blank

hard

Fill all three blanks to complete the schematic connection description.

PCB Design

In a schematic, a [1] resistor is placed between the input pin and [2], while a [3] resistor is placed between the input pin and GND.
