Load the processing file SmaHeartServer.pde.
Set the IP address of the iPad running LED Lab into the LedLabIp global variable.
Set the IP address of the iPad running Luminair into the LuminairIp global variable.
In the data folder, place 1 folder for each set of 4 tracks to be played.
In the data folder. place a single file titled "background.mp3" to be used as the background track.
Set the static IP of the server to the same value set in the Arduinos, 192.168.1.109
In LED Lab, go to the External Control Setup screen, and set Scene invocation to OSC, and set the address to /scene.
If we decide to go back to using OSC packets for the trigger, then in LED Lab, set the active scene to trigger from OSC, and set the single address to /trigger. This isn't actually in use right now.
In Luminair, open the settings, scroll down to "remote control", and select OSC input. Enable this, with the default port 8000.
In Luminair, make sure there are 5 different sequences to choose between. The app will use sequences 1 to 5.
The volume of the background track can be adjusted independently of the other tracks with the background_volume_db variable. Unfortunately it's in DB, so you will need to experimentally find a volume you like. 0.0 is maximum volume, and -100 is mute. It's a log scale.
Start the software. You should see the status printed to the application screen.
Keys:
'+' advances to the next set of tracks. '-' goes to the previous set of tracks. '1', '2', '3', '4' manually triggers the 4 inputs, respectively. '0' clears the state of the 4 inputs (in case something got stuck on.) Also re-syncs the audio tracks.
Operation: touching any input, either in hardware or on the keyboard sends a single OSC trigger to LED Lab.
when any manual input is active, the hardware inputs are disabled.
the DMX sequence changes whenever the number of active inputs (either hardware or manual) changes. Sequence 0 is activated every time the last input is released. Sequence 1 is activate when the first touch sensor is activated. Sequence 2 is activated when 2 touch sensors are engaged at the same time. So on for sequences 3 and 4.
When no input is active, the background track plays.
Tracks tend to fade in quickly and fade out slowly.
Main track fade time can be adjusted with the variables fade_in_time_ms and fade_out_time_ms
Background track fade time is the same for fading in and fading out, and is controlled by background_fade_time_ms.
The default set of tracks loaded is set to the 3rd folder (2, in a zero based indexing system). If fewer than 3 folders are present, it will default to the first folder. This can be changed with the default_track_set variable.
If Scene selection isn't working in LED Lab, do the following:
- check the IP address - does it match the one in the processing sketch?
- Restart LED Lab
- In LED Lab,go to the External Control Setup screen, and set Scene invocation to OSC, and set the address to
/scene.
Connect Ethernet first, then power. If the Arduino turns on before Ethernet is connected, you will need to restart the Arduino.
If the button feels stuck and is not clicking properly, it is probably being pushed up against the bottom plate inside of the enclosure.
Button Connections: Connect 1 pin on the button to pin 5, and the other pin to ground. You can swap these two.
use the center tab of the 3 tabs on the arcade button, and the tab at the end of the button. It's the tab that's mounded on the back instead of the side.
Ethernet Shield: Just swap these out, nothing to worry about. The one that already failed has a black X on the RJ-45 jack.
Arduino: This is a little more of a pain. Each Arduino has a number stored in memory - it's not in the code, it's in the storage on the chip. The Arduinos in use are numbered 1 to 4. A sticker on the back of each Arduino shows the number.
The extra board is number 5. The software by default will ignore it. To make it work, you need to make 1 change in the processing software, near the top of SmaHeartServer.
First, look at the back of the Arduino you are removing. It should have a number 1 to 4. Then, find this line in the code:
final int ReplacementBoardId = -1;
If you are replacing, say, board #3, replace -1 with '3'.
Run the program. Board #5 should now act like board #3.
Be sure to connect the button as mentioned in the hardware notes, to pins 5 and ground.
