Loop cards are a great game that can be played individually or as a class. They are perfect for review key vocabulary or questions at the end of a topic or when revising for an exam.
Instructions
Cut out the cards from the paper horizontally (but don't cut them in half!) and then shuffle them.
Now start joining each question on the right hand side of the card to the matching answer on the next card.
Carry on until all the cards loop together and you have competed the game!
Hint: Make sure that you set your paper to portrait to print 4 cards per sheet of A4 paper.
The rotational force produced by a DC hobby motor.
PWM
Pulse-width modulation, a method of controlling the speed of a DC hobby motor by varying the average power delivered.
Current
The flow of electric charge in a DC hobby motor, measured in units of amperes.
Motor Drivers
Integrated circuits or modules used to control the speed and direction of motors.
Overcurrent Protection
Safety feature that prevents damage to motors by cutting off power when current exceeds a set limit.
Brushed Motor
A type of DC hobby motor that uses brushes to transmit electrical current to the rotating armature.
Motor Shield
An expansion board for a microcontroller that provides additional features to control motors.
Stepper Motors
Motors that move in discrete steps, commonly controlled by motor shields for precision movements.
Voltage
The electrical potential difference that drives the current in a DC hobby motor, usually measured in volts.
DC Hobby Motors
Small electric motors used in hobbyist projects that are powered by direct current and suitable for various applications such as model cars, boats, and planes.
