With the help of microcontrollers, robots will also take on day-to-day tasks, such as
mowing the lawn. The BASIC Stamp module inside the robotic lawn mower shown in
Figure 1-6 helps it stay inside the boundaries of the lawn, and it also reads sensors that
detect obstacles and controls the motors that make it move.
Microcontrollers are also used in scientific, high technology, and aerospace projects.
The weather station shown on the left of Figure 1-7 is used to collect environmental data
related to coral reef decay. The BASIC Stamp module inside it gathers this data from a
variety of sensors and stores it for later retrieval by scientists. The submarine in the
center is an undersea exploration vehicle, and its thrusters, cameras and lights are all
controlled by BASIC Stamp microcontrollers. The rocket shown on the right is one that
was part of a competition to launch a privately owned rocket into space. Nobody won the
competition, but this rocket almost made it! The BASIC Stamp controlled just about
every aspect of the launch sequence.
From common household appliances all the way through scientific and aerospace
applications, the microcontroller basics you will need to get started on projects like these
are introduced here. By working through the activities in this book, you will get to
