Microcontrollers are one of the most useful circuit elements because
they are completely self-contained. These days you don't
even have to use an external crystal for the clock as you can turn on the internal
Did you know ?...
...that 98% of the
processors used today are microcontollers
for every 2 desktop computers you can see in an office there are 98
others that you don't see!. They are in everything toasters, microwave
ovens, security alarms, mobile phones,
petrol pumps, jogging
machines... the list is endless.
of the modern microcontrollers have a built in ADC, and
all have timers and many other useful modules. All you need to do is
decide what to use, and then activate the appropriate modules.
built in RAM and EEPROM that is re-programmable and programming them is
easy so you can change their operation very quickly - even in circuit!
