Serial.available and LED blinking - Arduino Forum
2023年12月29日 · I'm working on a project where I have two LEDs and I'm trying to write a program which flashes only one of the LEDs every 1000ms, if any character is entered via the serial monitor input, which LED is flashing should swap to the other LED. So far, I have the following: void setup() { Serial.begin(9600); for (int ledPin = 12; ledPin < 14; ledPin++) { …

Non-blocking infinite blink - General Guidance - Arduino Forum
2023年11月7日 · Hi all, 🙂 I am trying to write a blink function that takes the blink Intervalls (int num) as its first parameter and a stop condition (bool stop) as its second. I am using a non-blocking approach with a timestamp-based logic. The Blink function is supposed to either blink a specific number of times or just blink infinitely, depending on the arguments. When the button is …
How to Blink LEDs and Dim them at the same time using a
2019年8月6日 · Read the pot each time through loop(). Change the program so that the value derived from analgRead() is written to the LED on each pass through loop() when the LED state indicates that it is turned on, otherwise write 0 to it. Use analogWrite() instead of digitalWrite() to control the LED and use a pin that is PWM enabled.
How can I blink the LED on ESP32-S3-WROOM-1 - Arduino Forum
2024年2月4日 · /* Blink Turns an LED on for one second, then off for one second, repeatedly. Most Arduinos have an on-board LED you can control. On the UNO, MEGA and ZERO it is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN is set to the correct LED pin independent of which board is used.

How do you make an LED Blink once (HIGH for one second
2011年9月25日 · Hi, I'm pretty sure this is quite simple but don't know the best way to go about it. Basically I want to tell a digital output pin to be HIGH when triggered by the IF command, but only for a second. Then I want it to be LOW, until triggered again. The problem I'm having is that when triggered I can only figure out how to have it HIGH as a constant, unless I use a delay. The …
