Hello friends! My name is Nikolas and I am 15 years old. Today I’ll show you how to make a Smart Pull-Up Bar which, when you start doing Pull-Ups or Chin-Ups starts playing music in order to keep you motivated and after exercising for a certain period, a reward, a Tic Tac, in my instance gets dispensed! Make sure to watch the YouTube video below to see the Smart Pull-Up Bar in action and to follow the instructions from there if you prefer!
