frequency counter

The Arduino generates an accurate 1 second time base for the counter by cascading timer0 and timer2. The link between digital inputs 3 and 4 connects the output of timer2, 250 Hz, to input of timer0. Timer1 is a 16 bits timer, it overflows at the count of 2 power of 16, that in turn advances...

B4J app for measuring voltage and frequency using Arduino Nano or Uno. The frequency is counted over 1 second by dividing the 16MHz crystal, the ATMEGA328 can count up to 6MHz. The Arduino connects to the PC via USB. Sub Process_Globals Private fx As JFX Private MainForm As Form...

The Arduino generates an accurate 1 second time base for the counter by cascading timer0 and timer2. Part of the B4R code is in C for setting the timers/counters of the Atmega328, this way the accuracy follows the 16 MHz crystal. The link between digital inputs 3 and 4 connects the output of...
