INSIGNIA LABS FIVE SWITCH MUSICAL PIANO PROJECT KIT FOR SCHOOL COLLEGE PROJECT(Multicolor)

The project is a FULLY ASSEMBLED KIT. The project includes 5 keys to operate the piano/kit. All the switches are connected to resistors and a capacitor in series. Based on the key press, resistors value would add up which in turn would change the frequency of the speaker connected to 555 IC. Based on each switch press, the speaker outputs different sound.
