Timer Interrupt Uno R4 Minima - Arduino Forum
Hi, I want to use a timer interrupt on my Arduino Uno R4 Minima to execute a function in parallel to my program after a certain period (490 Hz). For the Uno R3 I have already managed this without problems for the timer 2 with the library TimerTwo. Since there is no library for the R4 yet, I have to set the registers myself. But I cant find the right registers in the datasheet to set the timer . . .

Start a timer when button is pressed - Arduino Forum
I am creating a timer for a race. I have a photosensor that has a laser pointed to so when someone crosses the finish, it trips the sensor, and the system logs the racers time. I am using millis() to time the race, but I need the timer to start when I push the button. I have tried using edge detection to start the timer, but the timer starts when the program starts, not when the program . . .
