555 Synthesizer App

New Release: 555 Synthesizer


The 555 synth app is now available via the App Store!  Documentation details will be posted here soon.  It’s free, so check it out!

Description:  A simple audio synthesizer that simulates the well-known 555 timer astable oscillator circuit.  Simply input the values of the desired electrical components  (Resistor #1, Resistor #2, and Capacitor #1), and the app will both calculate and synthesize a square wave tone with the appropriate frequency and duty cycle.  This app is a great educational tool for exploring the audible effects of each electrical component in a 555 timer oscillator circuit.  The app is also useful for quickly calculating the required electrical components to produce a particular square wave tone.  Last, but not least, it’s a pretty great noise maker.
