Control TV with AppleScript & Arduino

I have an interesting conundrum.

I have the following script, it works perfectly, but only if I run it from the editor. If I run it as run-only, or as an app, or if I run it using BetterTouchTool (which is brilliant by the way) a small part of it doesn't work. Specifically the part that deals with entering the digits on the screen.

This video shows script functioning properly when I run it from the editor:
https://www.youtube.com/watch?v=6ZN3farAoOs

This video shows the script being run as an app:
https://www.youtube.com/watch?v=Yr9qk5kpGJU

In the case of the second video, the Arduino is still functioning properly, as its status light blinks in time with each command, so I know it's not a problem there.

The problem seems to be with these lines:

Applescript:


do shell script h1
do shell script h2
do shell script m1
do shell script m2

They work if I run them from the editor, but not if I run them as an app, or via terminal or as run-only.


Any ideas as to why this might happen?

The full script is below if you are interested. If you want the supporting scripts, or the Arduino sketch, I can post them as well.

Applescript:


set commander to load script "/Library/Scripts/ArduinoIRCommands.scpt"
set controlArduino to "/Library/Scripts/arduino-serial-master/arduino-serial -b 9600 -p /dev/tty.usbmodem621 -s "

on setup()
   set usertime to my GetWakeTime()
   set confirmation to my CheckUserTime(usertime)
   return confirmation
end setup

set waketime to my setup()
set a to first item of waketime as integer
if a is equal to 0 then
   set a to 10
end if
set b to item 2 of waketime as integer
if b is equal to 0 then
   set b to 10
end if
set c to item 3 of waketime as integer
if c is equal to 0 then
   set c to 10
end if
set d to item 4 of waketime as integer
if d is equal to 0 then
   set d to 10
end if

set h1 to commander's getNUMBERS(controlArduino, a)
set h2 to commander's getNUMBERS(controlArduino, b)
set m1 to commander's getNUMBERS(controlArduino, c)
set m2 to commander's getNUMBERS(controlArduino, d)

commander's sendGET2WAKE(controlArduino)
delay 10
do shell script h1
do shell script h2
do shell script m1
do shell script m2
commander's sendWAKE2SLEEP(controlArduino)

on CheckUserTime(usertime)
   if (count of usertime) is not 4 then
       
       my setup()
   else
       return usertime
   end if
end CheckUserTime

on GetWakeTime()
   try
       display dialog "Use 24hr time." & return & "eg. 0929 for 09:29am" with title "Set TV Wake Time" default answer "1029" buttons {"OK", "Cancel"} default button 1
       copy the result as list to {button_returned, text_returned}
       set usertime to items of text_returned
   on error
       display notification "error -128 occurred"
   end try
end GetWakeTime

Re: Control TV with AppleScript & Arduino

I have found the problem now. It was embarrassingly simple.

It was simply a case of the script sending the commands too quickly. A simple delay 0.5 in-between each one fixed it nicely.

The scripts are below (with a few minor alterations).

Script for setting the LG's wake timer:

Applescript:


set commander to load script "/Library/Scripts/ArduinoIRCommands.scpt"
set controlArduino to "/Library/Scripts/arduino-serial-master/arduino-serial -b 9600 -p /dev/tty.usbmodem621 -s "

on setup()
   set usertime to my GetWakeTime()
   if usertime is false then
   end if
   set confirmation to my CheckUserTime(usertime)
   return confirmation
end setup

set waketime to my setup()
set a to first item of waketime as integer
if a is equal to 0 then
   set a to 10
end if
set b to item 2 of waketime as integer
if b is equal to 0 then
   set b to 10
end if
set c to item 3 of waketime as integer
if c is equal to 0 then
   set c to 10
end if
set d to item 4 of waketime as integer
if d is equal to 0 then
   set d to 10
end if

set h1 to my getNUMBERS(controlArduino, a)
set h2 to my getNUMBERS(controlArduino, b)
set m1 to my getNUMBERS(controlArduino, c)
set m2 to my getNUMBERS(controlArduino, d)

commander's sendGET2WAKE(controlArduino)
delay 10
do shell script h1
delay 0.5
do shell script h2
delay 0.5
do shell script m1
delay 0.5
do shell script m2
delay 0.5
commander's sendWAKE2SLEEP(controlArduino)

on CheckUserTime(usertime)
   if (count of usertime) is not 4 then
       
       my setup()
   else
       return usertime
   end if
end CheckUserTime

on GetWakeTime()
   try
       display dialog "Use 24hr time." & return & "eg. 0929 for 09:29am" with title "Set TV Wake Time" default answer "1029" buttons {"OK", "Cancel"} default button 1
       copy the result as list to {button_returned, text_returned}
       set usertime to items of text_returned
   on error
       display notification "error -128 occurred"
       set usertime to false
   end try
end GetWakeTime

on getNUMBERS(sc, x)
   
   return item x of {sc & "m", sc & "n", sc & "o", sc & "p", sc & "q", sc & "r", sc & "s", sc & "t", sc & "u", sc & "v"}
   
end getNUMBERS

Script for sending commands to the Arduino:

Applescript:


(*
   Arduino IR Commands for 22LG3000
*)



--set sc to "/Library/Scripts/arduino-serial-master/arduino-serial -b 9600 -p /dev/tty.usbmodem621 -s "


on sendMUTE(sc)
   
   do shell script sc & "a"
   
end sendMUTE

on sendVOLUP(sc)
   
   do shell script sc & "b"
   
end sendVOLUP

on sendVOLDWN(sc)
   
   do shell script sc & "c"

   do shell script sc & "y"
   
end sendWAKE2SLEEP

on sendCANCELSLEEP(sc)
   
   do shell script sc & "z"
   
end sendCANCELSLEEP

And the Arduino sketch which actually sends the IR commands (using the IRremote library by Ken Shirriff https://github.com/shirriff/Arduino-IRremote)

Applescript:


// Control 22LG3000

#include <IRremote.h>

IRsend irsend;
int incomingByte = 0;    // for incoming serial data

void setup()
{
Serial.begin(9600);
}

void loop() {

if (Serial.available() > 0) {
   // read the incoming byte:
   incomingByte = Serial.read();
Serial.println(incomingByte);
if(incomingByte == 97){
sendMUTE();

}else if(incomingByte == 48){

}else if(incomingByte == 98){
sendVOLUP();
}else if(incomingByte == 99){

As an example of using this set up, you can use Scenario (AppStore https://itunes.apple.com/gb/app/scenari … 4193?mt=12) to run a script on sleep. This is very helpful because the TV (which I use as one of my monitors) doesn't switch off when I put the machine to sleep. Often, pressing the on/off button on the front of the TV doesn't actually do anything, and I often lose the remote.

So, on sleep, Scenario runs this script:

Applescript:


set commander to load script "/Library/Scripts/ArduinoIRCommands.scpt"

set controlArduino to "/Library/Scripts/arduino-serial-master/arduino-serial -b 9600 -p /dev/tty.usbmodem621 -s "

commander's sendONOFF(controlArduino)

error "MCScenarioReadyToGo"

. . . and again on wake, only without the error as it isn't needed.

Using BetterTouchTool I can set the F18 and F19 keys to control the volume on the TV, and CMD+F15 to run the script at the top of the post.

It's a very useful setup.

Re: Control TV with AppleScript & Arduino

In case anybody is interested, I have rewritten one of the scripts to be far more efficient.

In case I forgot to mention it last time, you will need to use Tod Kurt's arduino-serial package (linked below)

The Arduino sketch stays exactly the same, but the one that is referenced as "ArduinoIRCommands.scpt" has been completely re-written as follows:

Applescript:


(*
   By Dan Barker 05/2014
   
   Arduino IR Commands for 22LG3000
   
   You will need:
   
   My blog post (if you're new to this sort of thing):
   [url]http://oneoclockjump.co.uk/2014/05/control-tv-via-ir-arduino-applescript-p1/[/url]
   
   Tod Kurt's Arduino-serial package:
   [url]http://todbot.com/blog/2013/04/29/arduino-serial-updated/[/url]
   
   Ken Shirriff's IRremote library:
   [url]http://www.righto.com/2009/08/multi-protocol-infrared-remote-library.html[/url]
*)


on signalTV(command)
   
   set sc to "/Library/Scripts/arduino-serial-master/arduino-serial -b 9600 -p /dev/tty.usbmodem621 -s "
   
   set commandlist to {"sendMUTE", "sendVOLUP", "sendVOLDWN", "sendAUP", "sendADWN", "sendALFT", "sendARGT", "sendSELECT", "sendMENU", "sendRETURN", "sendEXIT", "sendONOFF", "send1", "send2", "send3", "send4", "send5", "send6", "send7", "send8", "send9", "send0", "sendSLEEP", "sendGET2WAKE", "sendWAKE2SLEEP", "sendCANCELSLEEP"}
   
   set txlist to {"a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l", "m", "n", "o", "p", "q", "r", "s", "t", "u", "v", "w", "x", "y", "z"}
   
   set x to my getListPosition(command, commandlist)
   
   set command to item x of txlist
   
   do shell script sc & command
   
end signalTV


on getListPosition(this_item, this_list)
   repeat with i from 1 to the count of this_list
       if item i of this_list is this_item then return i
   end repeat
   return 0
end getListPosition

on getNUMBERS(x)
   
   return item x of {"send1", "send2", "send3", "send4", "send5", "send6", "send7", "send8", "send9", "send0"}
   
end getNUMBERS

This means that the script that did previously look like this:

Applescript:


set commander to load script "/Library/Scripts/ArduinoIRCommands.scpt"

set controlArduino to "/Library/Scripts/arduino-serial-master/arduino-serial -b 9600 -p /dev/tty.usbmodem621 -s "

commander's sendONOFF(controlArduino)

error "MCScenarioReadyToGo"

Now looks like this:

Applescript:


set commander to load script "/Library/Scripts/ArduinoIRCommands.scpt"

commander's signalTV("sendONOFF")

error "MCScenarioReadyToGo"
