Common Mistakes

Using 'IN' instead of 'OUT' when setting output mode.

Confusing pin mode with pin state (HIGH/LOW).

To set a pin as output, use GPIO.OUT.

Common Mistakes

Using 'OUTPUT' instead of 'OUT'.

Using 'INPUT' instead of 'IN'.

The correct constant for output mode is GPIO.OUT, not 'OUTPUT'.

💡 Hint

Common Mistakes

Using output mode instead of input.

Using pull-down resistor instead of pull-up.

Set pin mode to GPIO.IN and enable pull-up resistor with GPIO.PUD_UP.

Fill all three blanks to set pin 18 as output and set it HIGH.

Raspberry Pi

GPIO.setup(18, GPIO.[1])
GPIO.output(18, GPIO.[2])
state = GPIO.input(18) == GPIO.[3]

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using input mode instead of output.

Setting pin state to LOW instead of HIGH.

Comparing input to LOW instead of HIGH.

Set pin 18 as output with GPIO.OUT, set it HIGH, and check if input reads HIGH.
