Summary

In this chapter, an IR remote control tester prototype was built using an Arduino, a 16x2 LCD, and a littleBits remote trigger sensor module. A discussion on IR signals and communication protocols was provided in this chapter. The littleBits electronic modules were introduced in this section as a rapid prototyping tool for building electronic devices easily. Another design tool for code development, called Raptor, was also introduced. Raptor is a free software download that allows building interactive flowcharts. The interactive flowchart for the IR remote tester's pseudo programming language was converted to the Arduino code. Two versions of code were built using the serial monitor and the 16x2 LCD to display status messages of detected infrared signals from an IR remote control. Wiring diagrams and circuit schematic diagrams for the electronics were provided and discussed in this chapter.
