Power For Your Electronics Projects – Voltage Regulators and Converters

Today we are going to look at the somewhat mundane but absolutely essential subject of supplying power for your electronic projects. Trust me, this stuff is important! Electronic devices typically require either 5 or 3.3 volts, sometimes both.
Other common voltage requirements include 6 and 12 volts for motors and displays. Some complex designs (ie. a robot) require several different supplies with different current capabilities.
When you build your latest robot or IoT device you’ll need to consider how you’ll supply these voltages in the real world. On the workbench you can use a bench power supply if you have one, a USB adapter or even the USB port on a computer (just like with the Arduino).
