Course Description
We'll be covering..
- A prototyping process from drawing out the idea, putting it to words, creating specifications, and dialing in on our action steps
- Selecting suitable components
- Deep diving into the process of reading temperatures from a thermistor
- Studying an equation and implementing it into code
- Exploring Blink, an IOT platform, for developing mobile applications
- Writing code for communicating between your phone and an inexpensive WiFi-enabled Arduino-compatible board
- Creating an enclosure for your project
- And considering future development
Length of Instruction: 4 hours and 45 minutes of HD video instruction.
Import Notes: Transcripts of the videos are available on each course unit page. Relevant code is available on course unit pages.
