 ===Embedded Systems Questions===
-  - Were you able to program the Arduino?
-  - Did you have any problems during the Arduino process?
+What is an embedded system?
-  - What you think is the next step after this?
+An embedded system is a special-purpose system in which the computer is completely controlled by the device it controls. It preforms pre-defined tasks with specific requirements. It is a computer system with an included function within a larger mechanical/electrical system "embedded" as a part of a complete device often including hardware and mechanical parts. Embedded systems range from portable devices to larger stationary installates like MRI machines.
+What is a microcontroller?
+A microcontroller is a small computer on a single integrated circuit. It has a processor core, memory and programmable input/output peripherals. It is designed for embedded applications and they are used automatically controlled products and devices.
+SPI, ADC, UART, I2C: What do they stand for? What are they? What are they useful for? How are they all related?
+SPI - Serial Peripheral Interface; It is a synchronous serial communication interface specification. They are useful for short distance communication in embedded systems and for Secure Digital Cards and Liquid Crystal Displays (LCDs).
+ADC - Analog-to-Digital Converter; It is a device that converts physical quantities into digital numbers that represent the physical quantity. They are useful for recording music, scientific instruments and also for digital signal processing.
+UART - Universal Asynchronous Receiver/Transmitter; It is a computer hardware device that translates data between parallel and serial forms. They are useful for transmitting and receiving data back and forth.
+I2C - Inter-Integrated Circuit; It is a multi-master, multi-slave, single-ended, serial computer bus. They are useful for attaching low-speed integrated circuits to processors and microcontrollers.
+How do you think this information will relate to this lab?
+This information will relate to this lab because we will probably be using some of these items. We will be using microcontrollers to control the rest of the described parts of an embedded system in our updated weatherboxes.
