• Arduino and Embedded system Q/A

1. What is an embedded system?
   * Computer system that mixes electrical and mechanical hardware
2. What is a microcontroller?
   * Intergrated circuit (IC: Processor core, memory, programmable input/output, memory)
   * "Intelligence" of a system
3. SPI, ADC, UART, I2C
   a. What do they stand for?
      * SPI: Serial Peripheral Interface Bus
      * ADC: Analog to Digital Converter
      * UART: Univerasal Asynchronous receiver/transmitter
      * I2C: Inter Integrated Circuits
   b. What are they?
      * SPI: Four wire seial bus4
      * ADC: Converts voltage to digital number to represent amplitude
      * UART: Used for communications over a computer or peripheral device
      * I2C: Serial computer bus communication system that transfers data between computer or computer,
             mulit-master and multi-slave, single-ended
   c. What are they useful for?
      * SPI: Good for short distance communication in embedded system
      * ADC: Digital signals propagate better than analog signals (easy to detect noise)
      * UART: Computer hardware that translates between parallel and serial data
      * I2C: Bi-directional 2-wire bus
   e. How are they all related?
      * All needed for a circuit to work efficiently and communicate with the circuit
4. How do you think this information will relate to this lab?
      * We will be working with a lot of this device or with its concepts
