In this chapter, we met analog outputs and saw two different circuits to deal with two kinds of components that can operate on a variable voltage, an LED, and a motor.
On the hardware side, these circuits have helped us to learn about analog signals, DACs, and some of its characteristics. We also learned what a driver circuit is and how to use a transistor to create one, helping us know something more about this component. We even saw a very practical way to deal with high currents from Arduino without providing them from the Arduino board voltage regulator.
From the logical point of view, we met the
for loop, a very handy control structure that has helped us go over ranges of values and loop iterations.
By now, there's been enough about ...
