 Hello  all!
 
 Initially  this  was  going  to  be  only  a  diy  LED  hood  build.  But  one  thing  led  to  another  and  since  I  was  using  arduino  anyway,  I  decided  to  upgrade  to  automation  as  well...
 
 Features:  
 
 Bluetooth  control:  All  settings  are  accessed  through  phone  via  Bluetooth.  User  interface  is  kind  of  command  based  chats,  wherein  user  replies  appropriate  inputs  using  onscreen  guide  sent  from  arduino  to  phone.  (Better  explained  in  images  below)
 Individual  Channel  Brightness:    There's  3  LED  channels  -  cool  whites,  warm  whites  and  supplementary  colours  (deep  red  /  royal  blue  /  cyan).  Each  channel  brightness  can  be  set  individually  and  helps  a  bit  in  tweaking  the  looks  /  colour  temperature  and  also  the  maximum  overall  brightness.
 Timer:  Can  set  2  on  /  off  cycles  per  day.  This  helps  if  I  need  a  noon  siesta  sometimes.
 Ramp:  Instead  of  sudden  turn  on  and  off  of  lights,  I  can  enable  Ramp  up  and  Down  settings.  The  duration  of  transition  /  ramp  up  &  down  can  be  set  from  1  minute  to  1  hour.  Currently  its  15  mins.
 Temperature:  Takes  tank  and  room  temperature  every  ~15  minutes  and  decides  whether  or  not  to  switch  on  fans  if  temperature  is  above  user  defined  threshold  temperature.
 Fans:  Can  set  on  /  off  time  of  cooling  fans.  Its  also  linked  to  temperature  settings  above.  Means  even  if  time  control  says  fan  to  turn  on,  it  wont  if  temperature  is  already  below  user  defined  temperature  limit.  Currently  that's  28  deg.
 Co2:  Can  set  on  /  off  time  of  Pressurised  Co2
 Feeder:  Can  set  upto  2  feed  time  per  day.  The  feeder  is  simple  mg90s  servo  attached  with  tic  tac  container.
 Dosing:  Can  set  volume  (ml),  time  and  frequency  of  dosing  macros  and  traces  individually.  Frequency  can  be  daily  /  alternate  days  /  twice  a  week.
 One  Button:  There's  just  one  button  that  has  mulitiple  functions  i)  Single  clicks  -  Turn  on  /  off  lights  manually  (over  ride  timer  settings).  Manual  turn  on  only  stays  for  30  mins,  this  is  for  safeguarding  against  forgetting  to  switch  off  again.  ii)  Double  clicks  -  Turn  on  /  off  Bluetooth  for  10  mins.  iii)  Triple  clicks  -  feed  fishes  from  feeder.
 View  /  Save:  All  changes  made  in  settings  are  stored  in  RAM  and  not  in  EEPROM.  This  reduces  EEPROM  write  cycles.  Settings  in  RAM  and  EEPROM  can  be  reviewed  before  final  save  command.
 
 
 There‚Äôs  over  500  lines  of  code  written  from  scratch  by  myself  for  arduino  programming.  It  took  a  fair  amount  of  time  to  get  it  polished  and  compact  for  Arduino  Pro  Mini  which  has  low  memory  compared  to  an  Arduino  Mega  board.  Mostly  people  use  a  Mega  board  for  automation,  but  that  also  helps  in  adding  rich  features  like  colour  lcd  screen,  rich  UI  etc

 thanks!!     Smile  
 
 Sharing  some  pics  of  initial  prototype  board,  I  could  not  find  a  proper  long  pcb  board  so  had  to  stick  multiple  boards.  It  was  functional  but  looked  messy   Unsure  
 
 
 
 
 
 Then  later  upgraded  to  a  proper  pcb...

 Nice  setup  Clapping  
 
 Hope  you  had  good  learning  experience  and  satisfaction  post  this  setup.
 
 Just  curious  -  Where  you  got  the  fixture  to  connect  2  LED  rails/heat  sinks?

 Yes  it  was  indeed  a  great  learning  experience.  I  fried  2  arduino  boards  and  a  bluettooth  module  in  the  process   Very Happy  
 
 Those  are  3mm  and  6mm  acrylic,  I  designed  them  in  inkscape  and  got  it  laser  cut  at  acrylic  shop...

 Hello  there!
 
 Made  an  addition  of  temperature  graph  feature  in  the  app.  The  app  retrieves  log  of  5  days  from  the  microcontroller  and  then  plots  it  into  a  graph.
 
 It  shows  some  interesting  facts!  The  room  temperature  can  fluctuate  drastically  in  just  one  hour,  while  the  tank  temperature  responds  gradually  over  a  period  of  3  -  4  hours.  During  23/12/17  to  25/12/17,  I  had  kept  the  fan  settings  as  to  turn  on  at  7am  and  turn  off  at  11pm,  also  the  threshold  tank  temperature  at  which  the  fan  will  actually  turn  on  was  kept  at  27  deg.  However  as  you  can  see  the  tank  temperature  never  touched  27deg,  so  the  fans  never  turned  on.  But  since  26/12/17  i  changed  the  threshold  temperature  to  24deg  and  as  you  can  observe  the  tank  temperature  is  maintained  at  24deg  during  7  am  to  11  pm  after  which  the  fans  are  switched  off  and  temperature  rises  to  ambient  room  temp  at  night.  At  some  point  the  difference  in  room  and  tank  temp  was  6  deg!  Shows  how  effective  a  simple  cooling  fan  can  be...  If  i  keep  some  realistic  temperature  threshold,  say  28deg  during  summers,  i  hope  the  tank  temperature  to  remain  constant  throughout  day.  The  fans  will  automatically  turn  on  and  off  every  few  minutes  if  deviation  is  observed..
 
 
 
 Regards,
