Step 1: Testing the Neopixels 2/17/18
In this 30 minute video, James explains how to:
- Install the Arduino IDE
- Get the Adafruit Neopixel library
- Troubleshoot a bad NeoPixel
- Run the Standtest demo.
Step 2: Reading the Keyboard 2/18/18
In this 30 minute episode, James shows:
- How the Keyboard is physically wired
- How to divide 5 Volts into 7 (or 8) slices
- How to poll the keyboard and debounce it
- How to ensure freshness of data collected
- Guaranteeing accuracy by checking the input twice (like St Nick).
Step 3: Controlling the 7 Segments Using the Maxim 7219 Shift Registers 2/19/18 (2/20 Already If Computer on UTC)
Here is the 3rd video in our series, where James explains how to download the Maxim 7219 (LedControl) library and modify the example code to make use of all 21 7 segments + the 3 3 segments on your Open DSKY.
The .ino Arduino source code example is included for your convenience.
Step 4: Controlling the 7 Segments Using the Maxim 7219 Shift Registers (continued) 2/22/18
In this 20 minute installment, James starts with a good explanation of the schematic showing specifically how we wired the Max7219 Shift Registers.
He then shows us how to make any of the 7 segment display any character using the LEDControl library.
He also shows how to get our unique custom 3 segment to display a plus or minus character.
The resulting .ino code is included below.
Step 5: Intelligent Data From Gyro to 7 Segments
