...that 98% of the processors used today are microcontollers - that means 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.
Most 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.
They also have 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!
There are several FREE projects here (with source code in C) that you can use to learn about microcontrollers which includes an ultrasonic distance meter, an led matrix driver and many more (which you can find on the projects page).
Each Project includes source code, description and schematics which you can use as a basis for starting your own projects or just use them stand-alone.
Just Starting out ?
Check out the tutorial section where you'll find tutorials on building the circuits, device programming, prototyping and using high level languages.
Need some extras ?
The tips and techniques section gives information on designing specific circuits that either are difficult or that save you time and effort.
