Introduction: Electronic Piano Circuit

About: We create simple electronic projects and tutorials easy simple cool circuit

Electronic pianos are simple circuits that are usually seen in children's toys & doorbells. These circuits produce a musical sound or beep on pressing a pushbutton. So, in this project, we are going to build a simple electronic piano using a 555 timer IC by following simple step by step instructions.
