PIANO-ROBOT

A piano robot, in general, is a robot that controls piano instrument keys automatically. We will need to use a range of hardware tools, such as solenoids, to complete this project, as well as develop a specific Java software interface for it. The new piano robot speed tests prove some interesting records in the world. Since according to guinnessworldrecords.com on 4 March 2017 in Portugal The record for the most piano notes played in a minute has just been Wrecked by someone called “Domingos-Antonio Gomes” by hitting only one of the piano keys with two fingers 824 times, In one minute, Which means 13.7 per second. However, we have tested our piano robot speed, for only repeating two beside selenoids. By setting the delay time to 38 which means 0.038 sec to make the solenoid ON, then if we divide one second by 0.038 sec it equals 26.31 times playing the piano keys in one second, if we calculate it for one minute it will be 1578 times playing the piano keys. This is a record for only plying two keys. Later we decided to do another test by decreasing the delay time to 32, but this time we used for-loop inside the Arduino IDE The result will be dividing one second by 0.032 sec and it is equal to 31.25-time playing the piano keys one after the other in only one second, multiply it by 60 it will be 1875 times hitting the piano keys in one minute.
