Alarm
This time I am going to make an Alarm. For this I will use:
- Rp_ui_board
- 3pin earplugs ( I didn't have a speaker )
I want to make it possible that you can change the alarm time through the pushbuttons. The options you should get is:
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.
- CronTime3(Button 1)
Here you can set the hour you want the alarm to turn on.
- CrontimeTSE(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 press 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

For this I used the same script I explained in Blog 10. Only difference is that he opens other scripts.
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 $TimeOnhh) bw_tool -I -D /dev/i2c-1 -a 94 -w 11:20 bw_tool -I -D /dev/i2c-1 -a 94 -t "Time "`date +%T` sleep 1 done
CrontimeMM
This works the same as Crontime3, only
- TimeOnhh is changed to TimeOnmm
- Hours is changed to Minutes
Script AcTime
#!/bin/bash Min=$(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.
