Alarm Menu

This time I made an alarm that you can control through to the push buttons. For this I will use:

  • Rp_ui_board(User Interface)
  • 3pin earplugs ( I didn't have a speaker )

The options in the alarm menu:

Change alarm minutes
Change alarm hours
stop alarm music playing
Reset alarm time 
Activating the alarm time given
show on display current time + time of the alarm. 
  • AlarmMenu

Main menu where you can select the scripts

  • TimeAndAlarm(Button 3)

This will show at start up the time given as alarm and the current time.

  • CronTimeHH(Button 1)

Here you can set the hour you want the alarm to turn on.

  • CrontimeMM(Button 2)

Here you can set the minute you want the alarm to turn on.

  • AcTime(Button 6)

This will put the given hour and or minute in the crontab.

  • StopSong(Button 4)

To stop the alarm song/sound that is now playing.( killall omxplayer.bin )

  • ResetAlarm(Button 5)

This will reset the hour and minutes to 99 so that they won't be usable. ( because minutes goes from 0-59 and hours from 0-23)

How do you use my alarm?

When you start the script, you can use all the 6 buttons. When started up it will start at button 3. which is the button that shows the current time and time of when the alarm song plays. With button 1 you change the specific hour of when the song has to be played from the alarm. After button 1 pressed you change the hour with button 1 till 4.

1 = +1  
2 = -1  
3 = +5 
4 = -5

If you then want to confirm you want to have the specific hour you selected you have to press 5. With button 6 pressed you leave the script. ( If you didn't press 5 before 6 the given time will not be remembered ) Button 2 is in the same way designed as button 1 outside of it instead changing hours it changes minutes. Button 4 is just 1 button press to stop the song that is currently playing. When you get out of this menu it should be possible that it can play an alarm song again the next day. Button 5 will reset the alarm time to 99, so that it will never play an alarm. Button 6 Is to activate the alarm.

Scripts AlarmMenu

#!/bin/bash  

#BUTTON=CrontimeMM 
#BUTTON=CrontimeHH 
#BUTTON=AcTime 
#BUTTON=StopSong 
BUTTON=TimeAndAlarm 
#BUTTON=ResetAlarm 
bw_tool -I -D /dev/i2c-1 -a 94 -w 10:00 

while true; do 
 DETECT=`bw_tool -I -D /dev/i2c-1 -a 94 -R 30:b` 

 if [ $DETECT  != "00" ]; then 
   bw_tool -I -D /dev/i2c-1 -a 94 -w 10:00 
 fi 

 if [ $DETECT  = "20" ]; then 
   BUTTON=CrontimeHH 
 fi 

 if [ $DETECT  = "10" ]; then 
   BUTTON=CrontimeMM 
 fi 

 if [ $DETECT  = "08" ]; then 
   BUTTON=TimeAndAlarm 
 fi 

 if [ $DETECT  = "04" ]; then 
   BUTTON=StopSong 
   bw_tool -I -D /dev/i2c-1 -a 94 -t "Audio mute" 
 fi 

 if [ $DETECT  = "02" ]; then 
   BUTTON=ResetAlarm 
 fi 

 if [ $DETECT = "01" ]; then 
   BUTTON=AcTime 
 fi 

 bw_tool -I -D /dev/i2c-1 -a 94 -w 11:00 
  ./$BUTTON 

  sleep 1 
done

For this I used the same script I explained in Blog 10. Only difference is that he opens other scripts.


AlarmMenuStart.jpg

Script TimeAndAlarm

#!/bin/bash 

Min=$(cat Minutes) 
Hr=$(cat Hours) 

   bw_tool -I -D /dev/i2c-1 -a 94 -w 10:00 
   bw_tool -I -D /dev/i2c-1 -a 94 -w 11:00 
   bw_tool -I -D /dev/i2c-1 -a 94 -t "Alarm " $(printf %02d $Hr)":"$(printf %02d $Min) 

   bw_tool -I -D /dev/i2c-1 -a 94 -w 11:20 
   bw_tool -I -D /dev/i2c-1 -a 94 -t "Time   "`date +%T`

The script will read the given minutes and hours:

Min=$(cat Minutes) 
Hr=$(cat Hours) 

The read minutes and hours will then be printed on the display.

bw_tool -I -D /dev/i2c-1 -a 94 -t "Alarm " $(printf %02d $Hr)":"$(printf %02d $Min)

Script CrontimeHH

#!/bin/bash 

bw_tool -I -D /dev/i2c-1 -a 94 -w 10:00 

while true; do 
 Scan=`bw_tool -I -D /dev/i2c-1 -a 94 -R 30:b` 

 if [ $Scan  != "00" ]; then 
   bw_tool -I -D /dev/i2c-1 -a 94 -w 10:00 
 fi 

 if [ $Scan  = "20" ]; then 
   bw_tool -I -D /dev/i2c-1 -a 94 -w 10:00 
   TimeOnhh=$(( (TimeOnhh + 01) %  24   )) 
 fi 

 if [ $Scan  = "10" ]; then 
   bw_tool -I -D /dev/i2c-1 -a 94 -w 10:00 
   TimeOnhh=$(( (TimeOnhh + 23) %   24  )) 
 fi 

 if [ $Scan  = "08" ]; then 
   bw_tool -I -D /dev/i2c-1 -a 94 -w 10:00 
   TimeOnhh=$(( (TimeOnhh + 05) %   24  )) 
 fi 

 if [ $Scan  = "04" ]; then 
   bw_tool -I -D /dev/i2c-1 -a 94 -w 10:00 
   TimeOnhh=$(( (TimeOnhh + 19) %   24  )) 
 fi 

 if [ $Scan  = "02" ]; then 
   bw_tool -I -D /dev/i2c-1 -a 94 -w 10:00 
   echo $TimeOnhh > Hours 
   bw_tool -I -D /dev/i2c-1 -a 94 -w 11:20 
   bw_tool -I -D /dev/i2c-1 -a 94 -t "Set!" 
   sleep 1 
 fi 

 if [ $Scan  = "01" ]; then 
   exit 
 fi 

 bw_tool -I -D /dev/i2c-1 -a 94 -w 11:00 
 bw_tool -I -D /dev/i2c-1 -a 94 -t "Hours "$(printf %02d $TimeOnhh)
 bw_tool -I -D /dev/i2c-1 -a 94 -w 11:20 
 bw_tool -I -D /dev/i2c-1 -a 94 -t "Time  "`date +%T` 

  sleep 1 

done

Like the AlarmMenu it uses the same script as from Blog 10. Only what is special is:

echo $TimeOnhh > Hours 

Which sends the given hour number to a folder named Hours.

CrontimeMM

This works the same as CrontimeHH, only

  • TimeOnhh is changed to TimeOnmm
  • Hours is changed to Min


AlarmMinSettings.jpg

Script AcTime

#!/bin/bash 

Min=$(cat Minutes) 
Hr=$(cat Hours)  

(echo "#  mm hh dom mon dow command"; echo ""$Min" "$Hr" * * * mplayer /home/pi/ru.mp3") | crontab 

bw_tool -I -D /dev/i2c-1 -a 94 -w 11:00 
bw_tool -I -D /dev/i2c-1 -a 94 -t "Activated " 
bw_tool -I -D /dev/i2c-1 -a 94 -w 11:20 
bw_tool -I -D /dev/i2c-1 -a 94 -t "If times set"

The script read the minutes and hours given.

Min=$(cat Minutes) 
Hr=$(cat Hours) 

After that it puts the times in the crontab.

(echo "#  mm hh dom mon dow command"; echo ""$Min" "$Hr" * * * mplayer /home/pi/ru.mp3") | crontab

Script StopSong

#!/bin/bash 

killall mplayer

This will end all the mplayer files that are running.

Script ResetAlarm

#!/bin/bash 

Min="99" 
Hr="99" 

echo $Min > Hours 
echo $Hr > Minutes 

(echo "#  mm hh dom mon dow command"; echo ""$Min" "$Hr" * * * mplayer /home/pi/ru.mp3") | crontab 
   bw_tool -I -D /dev/i2c-1 -a 94 -w 10:00 
   bw_tool -I -D /dev/i2c-1 -a 94 -w 11:00 
   bw_tool -I -D /dev/i2c-1 -a 94 -t "Alarm " "$Hr":"$Min" "Res" 
   bw_tool -I -D /dev/i2c-1 -a 94 -w 11:20 
   bw_tool -I -D /dev/i2c-1 -a 94 -t "Time   "`date +%T`
Min="99" 
Hr="99" 

Will change the time, when the alarm goes to 99. ( A time that of course never get reached )

echo $Min > Hours 
echo $Hr > Minutes 

This is to save the times in the Hours and Minutes folder. So that if the time normally get showed everybody will see 99:99 as time. ( And not 00:00! I don't want to confuse people)

(echo "#  mm hh dom mon dow command"; echo ""$Min" "$Hr" * * * mplayer /home/pi/ru.mp3") | crontab 

Then it will put the times in the crontab and prints them out on the display.
