This spring, patches of the East Coast will turn buzzy and crunchy because of … bugs. Periodical cicadas (or Magicicadas) usually live underground but after 13 or 17 years, they emerge synchronously and in tremendous numbers to look for a mate. Radiolab launched a campaign to predict their arrival with a bit of DIY science and using an Arduino UNO.
You can follow the instructions of the simple tutorial on how to monitor soil temperature until it reaches 64° F (17,7 C°) — when the cicadas should start to emerge.
