Wildcard-LEDControl

Brian's house of LED development, code that will be run on the Arduinos to control the lighting on our 2018 robot.

Post season thoughts (4/30/18): Brian: While the animation portion is pretty, the overall project is buggy. It was fun though. Perhaps this can be perfected by future generations.

Hypotheses of Failure/Bugginess:

• The teensy's i2c was hanging occasionally due to no pullup resistor between signal and power?
• The radio interference coming from the motors caused weird signals to run through the signal line, causing it to hang?

Possible Solutions:

• Utilize the MCP2515 CAN Module for better signal reliability no single use of i2c.

Required Libraries:

• FastLED.h - lib for controlling WS2812B LEDs
• Wire.h - for i2c

Required Hardware:

• WS2812B LED Strip
• Arduinos/teensy
• 5V power source

Hardware Hookup Info:

5V power through 5V pin

⚠️ Caution: Use power source with sufficient amperage. ⚠️

Data through center LED strip pin - see code for proper pin on Arduino

blinkyMK2:

See layout: White wire - SDA

Red wire - SCL

Black wire - GND

Port closest to power terminal - for Underlighting

Other 2 ports - for Liftlighting

Description of Files:

blinkyMK1

The code for blinkyMK1, only controls the underlighting. Not recommended, does not use "state machine"/"FPS" control style

blinkyMK2

The code for blinkyMK2. Controls lift lighting. Can control underlighting, but it was never used. Version used for WildCard

blinkyMK3 - UNFINISHED

The code for blinkyMK3, possible implementation of MCP2515

__TestingRoom:

Some unfinished ideas or testing things. Take a look if you dare.

LED_Control_simple_patterns.ino:

Just 2 functions with LED subroutines in them. - Credits to Anna Li

LED_Control_complex_patterns.ino:

LED subroutines with more complex patterns. - also credits to Anna Li

i2c_Serial_Write_Master.ino:

A master device that will write a single byte to a slave device. You can choose the byte via serial monitor/console. Please be aware that pressing the key on the keyboard will send the byte.

i2c_LED_Control_Slave.ino:

The very first prototype of the code for the slave device controlled by the roborio. Will output a WS2812 pattern according to data sent from the Roborio via i2c. Will also print the LED Pattern ID if connected to the Arduino via serial.

i2c_LED_Control_Slave_MemoryHappy.ino:

Essentially i2c_LED_Control_Slave.ino but uses the MemoryFree.h library. It is just to fully verify that there will be no memory problems.

...Will possibly repurpose for Arduino Nano...

Good luck with your lighting!
