 حزام السعادة هو حزام يمكن لمرضى السرطان ارتداءه حول خصرهم في أي وقت وأي مكان. يقوم الحزام بمراقبة معدل نببضات القلب و تنبيه المريض في حال ارتفاع معدل نبضات القلب لديهم. وبذلك يمكن للأطفال المصابين معرفة متى يمكنهم اللعب و متى يتوجب عليهم الراحة. بالإضافة إلى أنه سهل الإستخدام و خفيف الوزن و يمكن المرضى من عيش حياتهم اليومية بعيدا عن المستشفى.

/*  Getting_BPM_to_Monitor prints the BPM to the Serial Monitor, using the least lines of code and PulseSensor Library.

--------Use This Sketch To------------------------------------------
1) Displays user's live and changing BPM, Beats Per Minute, in Arduino's native Serial Monitor.
2) Print: "♥  A HeartBeat Happened !" when a beat is detected, live.
2) Learn about using a PulseSensor Library "Object".
4) Blinks LED on PIN 13 with user's Heartbeat.
