Sport sensor
Budget: $30 – $250 USD
this project includes a zigbee antena with a teensy 3.6 arduino to make a capacitive sensor that works as a stopwatch and clock so that it has time stamps but it will have an 6ft led strip that will light up one color when something is in contact with the sensor and makes a time stamp but if there is a second contact with the sensor while there is still contact from the first time then there will be another time stamp from when the second contact happened and the LED strip will light up a different color
