So the project I am trying to make right now requires a sawtooth wave to be generated (for an RF transmitter). Anyways, the schematics call for a 555 Timer to pull this off. My question is, why can't my Arduino generate that? If it can, is there really any need for a 555 Timer? Or can you think …

What are some common appliances I can bust open to find a 555 timer?
