We finish off our Introduction to Electronic Components series with the voltage regulator, which is a useful little thing. Sometimes, you have more voltage than you need—say, when you’re working with a 9 volt battery but you need 5 volts for your circuit. Also, if your project is especially finicky, they can also take in a fluctuating amount of voltage and emit a perfectly constant value.
If you’re looking for more about other components (say…diodes, buttons and switches, resistors, etc etc) check out the whole playlist!
Resistors…resist. It’s what they do. Well, they don’t resist everything. They won’t help you resist the temptations of the dark side, for example. But these little guys are useful components when it comes to regulating the amount of electricity with which you want to work.
