I bought an arduino, just for its LED blink lol.
But i realised that it can only clock a maximium of 500hz, Ton = 1ms, Toff = 1ms.
This is really strange as the on board oscillator is 16MHz, magnitudes higher than the 500Hz.
Having delay <1ms comes out with nonsense. I plugged out output from the arduino to a transistor to drive a speaker, and having <1ms doesn't come out with the correct frequency. eg delay Ton = .5ms, Toff .5ms, Freq = 10KHz, but my speaker isn't doing 10KHz.
My transistor is rated for over 300MHz bandwidth, its not with my power supply either.
Anyone knows if i can get maybe >100k square waves out of an arduino?
