I'm posting here a simple project to create an interrupt timer on an ESP32 board for version 3.1.1 by Esspressif Systems. I had difficulties to find updated information to make this code, I hope it can be useful to so...
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 racer's time. I am using millis() to time the race, b...

Call the timer () function to initiate (or in case of timer (0) to stop) the timer, i.e the script in your button click event should write only the following: rows=99 timer (3) (the rows variable should be declared in...
Hi! I'm looking for a timer library. I am confused about how many related libraries are available. I would like to have one with rollover protection, delay on, delay off, blink, and easy to use. What do you suggest?
As you understand I need a hardware timer (counting clock ticks). Millis () makes demanding to ckeck if "old value" is smaller than millis () value (normal run from start until rollover) or greater (1st time after rol...
Hello together, here I'm new but I have some experience with HC08 µC programming in C and Assembler. I try to use an Arduino Uno R4 Wifi to capture an input signal with GPT321. Unfortunately I didn't found an example ...
Hi all , after spending every spare moment over the last few weeks reading the forum and googling , I keep going around in circles getting no where. So I have joined the forum in the hope that I can get help . I am no...
The title tells most of the story. I need to setup Timer 1 for a 1 millisecond interrupt period, and need to use the same code on both the Arduino UNO 5V 16Mhz and the Arduino Pro Mini 3.3V 8Mhz. I found these settings …
Set up a timer overflow interrupt that increments a counter each interrupt, when it reaches the number you calculated set a bool variable (flag) in the interrupt.
