Soon after Pokeman Go released, the safety issues of playing this game outdoor have drawn a lot of attentions. Players run on the street without watching traffic,even one of them fell down from bridge. It is difficult to be aware of surroundings through a camera lens while playing the game. To avoid potential hazards, I decide to make a Pokemon safety badge to trigger motor when the distance between wearer and any object is less than one meter.
It takes 5 minutes to make this project including assembling parts and uploading the code. Zero hardware background is required. Check out the demo video below. Pikachu~
