Answer the following questions in a detailed essay format. No answer key is provided.

1. Describe the complete process, from hardware connection to software configuration, of uploading a program to an Arduino board. Detail each of the eight steps provided in the “Arduino – Installation” guide, including the function of each symbol in the IDE toolbar.
2. Analyze the different types of communication protocols discussed: Parallel, Serial (UART), Inter-Integrated Circuit (I2C), and Serial Peripheral Interface (SPI). For each, explain its basic principle, the number of conductors used, and any key characteristics or functions mentioned.
3. Compare and contrast the three types of motors detailed in the source: DC, Servo, and Stepper motors. Discuss their unique operational principles, how they are controlled, and the specific components (like transistors or driver ICs) required to interface them with an Arduino.
4. Explain the concepts of pins configured as INPUT and OUTPUT. Discuss the high-impedance state, the use and implementation of pull-up resistors (both external and built-in), and the low-impedance state, including the current limitations of Atmega pins.
5. Provide a comprehensive overview of the data types available in Arduino programming. Select and describe five distinct data types, including int, float, boolean, char, and long, detailing their memory size, range of values, and a sample use case for each as shown in the source.
