Resources and Going Further
Now that you've got the gist of one of the most common concepts in electronics, there's a world of new stuff to learn!
Would you like to learn how a microcontroller, like an Arduino, could read the analog voltage produced by a voltage divider? You can do so with our analog-to-digital converters tutorial.
Learn how to use varrying levels of voltage to control other devices with our pulse width modulation tutorial.
