Arduino millis overflow handling serial#
The crystal oscillator is usually needed for things like serial communication in order to control the baud rate. The video above states this, but in reality, most Arduino use a ceramic resonator for time keeping. The integrated circuit that an Arduino uses has a built in hardware clock. Some are precise, some you can make yourself on a breadboard, and some are built into modulus that we can connect to our Arduino. There are a lot of different circuits that can generate voltage signals. Hang in there!Ī hardware clock is an electrical circuit that creates a signal (like a voltage pulse) at a consistent frequency. Specifically, let’s discuss what a “hardware clock” is and what a “timer counter” is. What is this millis() function anyway? Before we can explain this, we need some context.

Have you heard of the Arduino millis() function?ĭid you know that it gives you access to the Arduino internal timer counter hardware which can be used for the timing of different events?
