  1. Gateway To Space ASEN 1400 / ASTR 2500 Class #12 T-58 Colorado Space Grant Consortium

  2. Today: • Announcements • Next Time • One Minute Report Questions • Arduino Part 1: Type and Blink

  3. Announcements: • Everyone bring HW #4 and #5 hardware? • USB cables? • Arduino Unos? • Laptop?

  4. Announcements: • Review Syllabus changes…

  5. Announcements: • Meetings tomorrow: • 7:15 Team 2 • 8:00 • 8:45 • 9:30 Team 4 • 10:30 Team 1 • 11:15 • 1:00 Team 5 • 1:45 Team 6 • 2:30 Team 3 • 3:15 Team 8

  6. Announcements: • Bring proposals, comments, and grade sheets • Bring questions and comments • Bring homework #6 – multiple copies if ordering from different locations • Bring budget • Whole team does not need to be there

  7. Announcements: - Grades received yesterday - Need to add proposal and presentation scores - Will hand out passwords and post grades on Tuesday - Late 1 Minute Reports and those on different paper…

  8. Announcements: General Proposal Comments: - HOBOs – Why? - GoPros – Many are using… - Imaging tests - Schedules are your plans to launch and your team's grade. Make them detailed. - Testing, like schedules must contain a lot of thought.  Test everything and then test it some more. Test with mass sims. - Sensor calibration - Practice taking data and analyzing it - Requirements – RFP vs. Mission - Mission – WHY and WHAT - Arduino plan and usage – What you get - Industry examples

  9. Announcements: General Presentation Comments: - Late vs. On-time - Practice vs. not practice - Eye Charts - Reading the slidesand eye contact - Introductions - Answering questions - Overall, pretty good presentations

  17. Arduino Part 1: Type and Blink Class #3 Colorado Space Grant Consortium

  18. Arduino Overview: What’s under the hood? External Interrupts 14 Digital Input/Outputs GND Serial I/O ATmega328 - 10 Bit ADC - 16 MHz - 32 KB Flash - I2C & SPI - 40 to +85C USB 5.0 V Regulator 9V DC Power In 3.3 V 5.0 V GND 6 Analog Inputs

  19. Arduino Overview:

  20. Arduino Overview: The Easy Stuff… GND USB 5.0 V Regulator 9V DC Power In 3.3 V 5.0 V GND

  21. Arduino Overview:

  22. Arduino Overview: The Chip… ATmega328 - 10 Bit ADC - 16 MHz - 32 KB Flash - I2C & SPI - 40 to +85C

  23. Arduino Overview:

  24. Arduino Overview: Other… External Interrupts 14 Digital Input/Outputs Serial I/O 6 Analog Inputs

  25. Arduino Overview:

  26. Digital: • Bits and Bytes, On/Off, 1 or 0, high or low, non-continuous Red line – 2 bits = less info Green line – 4 bits = more info

  27. Digital: • A state is one unique combination of bits • 1 bit – 0 or 1 = 2 states = 21 • 2 bits – 00, 01, 10, 11 = 4 states = 22 • 4 bits – 0000, 0001….1111 = 16 States = 24 • 8 bits = 00000000….11111111 = 256 states = 28 • 16 bits = 0000000000000000…1111111111111111 • = 65,536 states = 216 • More bits provides more precision over a given voltage range • If it is necessary to record small changes, more precision (bits), is required • 8 bits is a byte • 10 bits is how many bytes?

  28. Analog vs. Digital • What is the difference between 8-bit and 10-bit conversions? • An 8-bit conversion has 28 (0 to 255) possible values, • Resolution is 1/(28 – 1) * 5V = 1/255 * 5V = 0.0196 V

  29. Analog vs. Digital • A 10-bit conversion has 210 (0 to 1024) possible values • Resolution is 1/(210 – 1) * 5V = 1/1023 * 5V = 0.00489 V • For a device that is very precise, a 10-bit conversion allows for a higher resolution on the data (high-range accelerometers)

  30. Analog vs. Digital 42.0 C temp Real World Real World to Analog Voltage 4.20V = 42.0 C 2 bit ADC 0C = 0V 50C = 5V 5V = 3 3 = 11 binary 4.20V = 4 (4.20V / 5.0V * 4) = 3.36 = 3 0V = 0 Storage for later use ADC = Analog to Digital Converter = Voltage to Binary

  31. Sensor & Storage 42.0 C temp Real World Real World to Analog Voltage 4.20V = 42.0 C 10 bit ADC 0C = 0V 50C = 5V 5V = 1023 860 = 1101011100 binary 4.20V = 860 (4.20V / 5.0V * 1024) = 860.14 = 860 0V = 0 Storage for later use ADC = Analog to Digital Converter = Voltage to Binary

  32. Arduino Overview: Let’s take it for a drive… External Interrupts 14 Digital Input/Outputs GND Serial I/O ATmega328 - 10 Bit ADC - 16 MHz - 32 KB Flash - I2C & SPI - 40 to +85C USB 5 V Regulator 9V DC Power In 3.3 V 5.0 V GND 6 Analog Inputs
