Sketch to control lighting and other functions for custom vehicle wiring. Outputs should be wired to fuse protected relays to power devices. Resistors should be used to any inputs to protect against false digital reads.
The sketch was designed and debugged against the Arduino Portenta H7. The sketch is stable and will work with any Arduino board, however debugging functions are specfic to Portenta and may not compile on other boards if debugging is enabled.
- Edit lines 5-17 to match your input and output pins
- Load sketch
Inputs and outputs are predefined when instantiating the Vac class. For any inputs or outputs not needed simply leave a 0 for the pin number.
| Variable Name | Description |
|---|---|
| turnLeft | Input for left blinkers |
| passRight | Input for right blinkers |
| hazards | Input for hazards (both blinkers simultaneously) |
| tails | Input for tail lights |
| brakes | Input for brake lights |
| heads | Input for headlights |
| Variable Name | Description |
|---|---|
| driverBlinkers | Output for driver side blinkers |
| passengerBlinkers | Output for passenger side blinkers |
| tailLights | Output for tail lights |
| brakeLights | Output for brake lights |
| headLights | Output for headlights |
| Variable Name | Description |
|---|---|
| timing | time in milliseconds between blinker states |
| autoTails | setting to link tail light output to headlight input |
| debug | turn debugging (serial output) on and off (0 or 1). |
Most of the code that executes is housed in a custom library that handles all timing/switching/sensing. The library is flexible enough to take inputs either created in the library itself on instantiation or using pins defined on the Arduino sketch side. Predefined functions for custimzation are listed below.
Below are fuctions that can be reused throughout the sketch
This function is for simple switching by reading for a HIGH input and writing HIGH for one output. Defaults to LOW for output.
This function is for simple switching by reading for a HIGH input and writing a HIGH output for two defined outputs. Defaults to LOW for both outputs.
This function assumes 4 blinker outputs that are defined in the library itself with provided values on class instantiation. The blink duration between on/off can be customized by editing the 'timing' variable in the Arduino sketch. A hazard switch feature is also included to turn on all blinkers when hazard switch is HIGH.
This program does come with limited debugging feedback. Simply set the debug value in Vac class declaration in Arduino sketch to desired value.
- Add comfort blinker timing function with definable timing and blinks
- Provide functionality for low and high beams
