Reading Datasheets
One of the most important skills that you can develop as an engineer is the ability to read datasheets. Just about any electronic component that you can buy has an associated datasheet that contains information about the technical limits of the part, instructions on how to use its capabilities, and so forth.
Breaking Down a Datasheet
Consider the datasheet for the Microchip/Atmel ATmega328P, for instance. Recall that the ATmega328P is the MCU used in the Arduino Uno and many Arduino clones. To find the datasheet for most parts, you can just perform a Google search. For example, to find the datasheet for the ATmega328P, just search for ATmega328P datasheet on Google and look for the first PDF link from the manufacturer's website (microchip.com
in this case). The datasheets for the MCUs used in official Arduino boards can also be found on the hardware page for each board on the Arduino.cc
website. When you have the datasheet in hand, start by reviewing the first...
