What is this Red Light Green Light Game System?
It comes from the most popular Netflix TV show Squid Game about a series of deadly games, but don't worry! The game I'm showing you has all the bad stuff taken out, so it's totally safe to play with children.
Rules of this game:
The players' goal is to reach the finish line before the countdown on the laptop stops. Players must freeze when the red light is on and move forward when the green light is on.
The game without high tech is introduced in the second video.
Tech brief introduction:
1. Before the game starts, all players must wear a Microbit beacon on their arms.
2. The Microbit beacon can detect if a player is moving with its onboard accelerometer.
3. The beacon also constantly sends a radio signal to three receivers with antennas facing up and one receiver with the antenna facing all the players at the finish line. This setup can be used to detect if the player has reached this finish line. (I explained how the system works in the first 20 minutes long video.)

Install the Processing Programming Environment
Link for the Processing Programming Environment: https://processing.org/download
Link for the RedLightGreenLight Processing Code:

After installing the Processing Programming Environment, you need to add the official Sound library.
Set Up the Radio Proximity Sensing System
Receiver 2, 3 and 4 are 1.5 meters apart. When setting up this configuration, it is important to ensure that nothing gets in the path of communication lines between Receiver1 and the other three receivers on the floor. Receiver1 is connected to a laptop computer. Receiver1 controls the Processing APP on the laptop switch between red light, green light and playing voice instructions via serial port.
Make sure receiver 2, 3 and 4 are placed on the floor with the exact same direction as it is showed in the green background picture. Beacause my experiment are based on this configuration.
Next, turn on all the beacons,receivers, run the Processing code,and press the button A on the remote control to start the game. Have fun!
