Arduino Mega 2560 Light and Shade Controls
Assumptions:
Arduino Mega or clone used

–
Shade and Light control program on separate Megas – not combined on one
Try to maximize number of out pins and in pins on each version – lights and shades
Requirements Shades:
shadeUpTimer and shadeDownTimer implementation: critical to make sure up and down relays are never on at the same time
Configurable timer and switch to shade mapping via serial interface and web –
Configuration conserved across reset
Configurable to send shade and switch status via serial and/or web interface
NTP client
Webserver
HTTP
Heartbeat monitoring from Raspy – with configurable timeout – initially 30 minutes
UDP – used for initiation registration of arduino with Raspy
Broadcast
Multicast

Слайд 3

Arduino Mega 2560 Light and Shade Controls
Future Development:
Arduino web interface consolidation

on Raspy
Configuration storage in db on Raspy
ArdID storage on Raspy
Authentication controlled by Raspy through web interface
Tunneling out to cloud from Raspy
Registration Procedure
Secure communication – potentially implementation of chacha encryption if possible
Thoughts about this – maybe a second Arduino is needed just for the comms?
Physical interfaces
Input I/O protection against overload and EMF etc.
Output I/O protection against overcurrent
Transistors?
Optical isolation?

lightOffTimer not yet implemented –
Timer to be

settable via web interface for each light independently
Light Status and Timer to be written to EEPROM to conserve the value through restart

lightTimerSet
After 1.5sec timeout

Count number of pushes and set lightOff Timer

Слайд 5

Light Controls
Startup/Setup
check for all timer values in EEPROM – if there

use those if not use hardcoded default values
lightTimer[numOfLights]
Light timer to be configurable during runtime – by webserver or serial interface or via switch as below
If light switch is pressed quickly [y] number of times then light timer is set to y*15minutes
check for Light Status for each light in EEPROM and set appropriate outPin – cycling through all pins and initializing – put a delay between each so that you don’t generate too much current at the same time
Intitialize all needed global variables
Initialize all inPins and outPins
Check for device ID in EEPROM – if none then starting first time – make firstTimeStart variable True
Check for Mac Address in EEPROM – if default then make defMac variable True
Setup Mapping of inPin[x] -> outPin[x] – many to one (I haven’t done this yet – not sure how)
This should be configurable – so not constants but changeable during runtime
Read timeOfDayOn[] timeOfDayOff[] for each light – default is always on – to be made configurable by the web server or serial interface

Слайд 6

Light Controls
Main Loop
Check if first start – if ArdID is not

default then not starting first time –
If NOT first time
Go to Program Loop
If first start init NTP, Webserver
Look for Raspy by sending out multicast or broadcast
Check for message from Raspy initiating registration
Raspy answers with raspyID and ArdID
Set ardRegWithRaspy = True
Raspy ID is written to EEPROM
ArdID is written to EEPROM

Maybe below is better in the Startup/Setup phase

Слайд 7

Light Controls
Program Loop
Check status of all InPin[x]
If status is high –

Check lightStatus[y] where y is the light that is manipulated by this particular inPin[x] based on the mapping
If lightStatus is On
go into routine to turn off light
If lightStatus is Off
go into routine to turn on light
Check NTP and update clock
Check inbound ethernet interface and HTTP
Check connectivity to Raspy if exists and if registered – if ardRegWithRaspy = True
Check for request for configuration page on HTTP
Go to function to process inbout webpage
Go to function to process response
Back to start of Program Loop

Light Controls
fnTurnOnLight(x)
Debounce Timer – settable but currently 200ms
Count number of times

pressed in z time in sec ( z to be configurable) 1.5sec initially thinking
If only once then use lightTimer[x] value as gotten when initialized
If more than once-
Start light timer based on above z*x where x = integer(minutes) or equivalent millis()
Set outPin[x] to value to turn on light – may be high or low depending on config
Set lightStatus[a] per config mapping

fnTurnOffLight(x)
Debounce Timer – settable but currently 200ms
Stop light timer
Set outPin[x] to value to turn off light depending on config
Set lightStatus[a] per config mapping

Timer required to calculate if shade full open

or closed or 50% open etc.
Total time for closing and opening and incremental positions by 10% independently so timer for closing is different than for opening as shade changes speed as it rolls up and down
