What is a microcontroller?
A tiny programmable computer.
A series of actions/steps that lead to a clear result
The information or data entered in a system by a user
The information or data produced by a system based on the input information
Microcontrollers are "embedded" inside some other device so that they can control the features or actions of the product.
True
False

Microcontrollers can program themselves.
True
False
Microcontrollers “listen” to sensors and “talk” to actuators. They decide what to do based on a set of instructions (program) that you write.
True
False
Basically, any product or device that interacts with its user has a microcontroller buried inside.
True
False
Sensors receive input from the world and transfer that information to the Microcontroller, but how the Microcontroller responds is determined by a set of instructions that programmers create.
True
False
Microcontrollers are complete, miniature, programable computers.
True
False
Sensors are inputs; they “listen” to the physical world.
True
False
Actuators are outputs; they “take action” in the physical world.
True
False
A microprocessor is only the CPU of a computer.
True
False
A microcontroller is a complete microcomputer with integrated inputs, outputs, memory, timers and other essential items.
True
False
Microcontrollers are easy to use, troubleshoot and maintain, programmable and easily interfaced.
True
False
