Building Arduino-Based Peripherals

One of the greatest forces in empowering the Internet of Things (IoT) as you know it today has been the expansion of access to lower-cost, higher-quality electronics components and communications standards that were once only available to large companies. Previously, if you wanted to learn how to program a microprocessor, you would have to buy a high-performance computer, chip programmer, blank chips, and an expensive software license from the chip manufacturer. Today, you can program all the hardware projects you want with a single $30 Arduino, Raspberry Pi, or BeagleBone microcontroller board, and you can find a wide variety of sensors with two- or three-pin connections built in for less than $10.
