Roshamglo Hookup Guide

How to Use the Roshamglo
To use the Roshamglo, first make sure that the board is on. When you move the power switch to "ON", the red LED should illuminate.
How to Play
Playing the game is very straight forward, next to the 5-way switch are three images that correspond to your three possible moves: rock, paper, and scissors. To set your move as rock, you will push the switch to the left towards the rock image. Paper and scissors are played the same way, but this time towards their corresponding images. When you move the switch, the green LED will flash quickly every time the IR LED sends a signal. Once the LED starts to blink, you'll want to point the USB connector towards your opponent's controller.
If you've pressed the button by mistake, you can press the switch in any direction to cancel the move. Once you select your move though, the green LED will blink for a few seconds. After both sides have received their opponent's move, the center LEDs will display one of the following:
- Solid red - lose
- Solid green - win
- Alternating red and green - tie
- Blinking red - see explanation below
- Fading - timeout. Try standing closer to your opponent and aiming your USB connector at their USB connector
A blinking red LED could mean one of two things. One possibility is that you have played against an opponent too many times. Each controller has a unique ID and your Roshamglo will not function with the same opponent after 15 rounds. We want the Roshamglo to start a conversation with people around you, and the Roshamglo can be used to help break the ice. So walk around and continue on your quest of total domination! Another possibility is that the score saved to your controller is full. You can dump your points by heading over to the scoreboard station.
Viewing and Uploading Your Score
You can view your score by closing the 5-way switch's center switch (push the switch straight down towards the top of the board). Each time the green LED turns on, represents one point. The score is saved to a 8-bit register, which means that the maximum score you can have saved is 255 points. You can clear your score by uploading it to the scoreboard station. If the LED is red, it means that your current saved score is 0.
To upload your score, head over to the scoreboard station. With the board powered on, insert the board to the station and move the 5-way switch to the down position (towards the SparkFun Logo and lanyard clip). Just like when you're playing a game, the green LED will flash a few times. The score will be successfully read when the LED changes to solid green. If the LED is solid red, that means that it was not able to read the score.
Summary of the LED Indicator
If the center LED is fading on and off, it means you're in standby mode. In standby, the board will go into a deep sleep for two seconds, and then wake up to fade LED on and off. Pressing the 5-way switch in any direction will wake up the Roshamglo and perform the function attached to that switch. There are three other modes that control the LED, those LED patterns are described below.
