If your Arduino application only needs to display numbers, consider using a seven-segment display. blogspot Arduino Mega 2560 Pin Diagram - 70 New Release Images Of Arduino Mega 2560 Pin Diagram , N Ch Mosfet Irfz44n An Arduino Pro Mini by Adlerweb On,working with Arduino Simulator 1 0,grbl Arduino G Code Processor – Pin Layout,arduino Mega 2560 Schematic Arduino Free Engine Image,schematic Of Arduino Uno Input Output Pins and atmega328 2 Sneak Preview The TICC is an electronic stopwatch that can time events with 60 picosecond resolution "Shield" form factor that connects to an Arduino Mega 2560 Useful for Time-Nut applications: frequency and stability TIMER/Counter2 is a 8 bit and the associated counter TCNT2 is increased +1 each clock tick. Overview. Visitar. TCCR1B register’s 3 first bits saves value of counter clock prescaler: By setting TCCR1B register to 0x04 we using /256 prescaler. Arduino Mega's pin 49 may be used by the SPI library, or SPI-based libraries like Ethernet or SD. Here is sample code that will work with the arduino. The code (Arduino sketch) allows push button increment of the counter from 0 to 9. I tried to just put the RX/TX pins the hardward uses and it didn't work. Here is a source code which i've found it in a book: unsigned Fast PWM on ATmega328, up to 8MHz sacrificing duty cycle resolution to get higher frequency. arduino mega 2560 frequency counter
