Meet "HeartRace", the winner of @deloittedigitalsa's 24 hour hackathon. Our brilliant developers and designers connected a scalextric track to a Bluetooth heart rate monitor, using a Raspberry Pi computer and an Arduino board. The result is a set of little cars racing around the track with an acceleration based on heart rate. They even created an iPad app to watch the cars go around. 📷 @headphase_sa #nerdalert #deloittedigital #hackathon #innovation
