Total questions: 30
Worksheet time: 15mins
What is the purpose of an H-Bridge in motor control?
To control voltage only
To control motor direction by switching polarity
To supply power to Arduino
To measure speed
PWM stands for:
Pulse Wide Modulation
Pulse Width Modulation
Power With Modulator
Programmable Wave Modulation
A wider PWM duty cycle means:

Supply power
OUT1 and OUT2 are connected to:
Arduino
Motor A
