One step closer to counting the frequency




In this picture: signal generator generating a 449 Hz triangle wave, the lm311 circuit converting the 15 volt signal to a 5v square wave and the prototype card, displaying the value (in timer clicks) between pulses. The only thing left now is to convert from period to frequency :-)
