Combining led blink and fade (PWM) - Arduino Forum
May 19, 2018 · Hello, beginner here! I had a project using several led stripes, and I wrote a rundown for it and rundown would be like this: All led fade in - stay 255 for 5 sec - all led fade out - all dark for 1 sec - led 7 fades…
'Blink' doesn't work? - General Guidance - Arduino Forum
Apr 21, 2016 · How about connecting your LED and resistor to the pin that is blinking. You have the LED connected to 5V and gnd from what I can see, it will stay ON because they are the power supply pins. You need to connect the LED and resistor to pin 13 and gnd. The blink sketch outputs to the LED and pin13. Tom....

Pro Micro (Leonardo?) Help with blink test - Arduino Forum
Jun 4, 2020 · The board also has a fuse on the power input. It shows up as an "Arduino Leonardo" in the Arduino IDE and works out of the box (no drivers required, tested on Win10). I was able to find a reference to a pin 17 to modify the Blink example and uploaded it successfully, as the one small onboard LED started to blink.
XRAD'S issue with fade and blink switch functions LED
Mar 11, 2025 · I have tried many different variations of fade and blink combos, and checked the variables and libraries, but the LEDs (basic LED with 200 ohm resitors) freeze funtion no matter what I have tried. I have looked at the library files and I do not know what I am doing wrong. Using HC-SR04 distance ultrasonic sensor for distance change and Teensy 4.0. Either BLINK or FADE functions work fine by ...
LED "pulse" instead of "blink" - Programming - Arduino Forum
Aug 18, 2016 · To make the pin "pulse" for 7 ms: digitalWrite(ledPin, HIGH); delay(7); digitalWrite(ledPin LOW); Actually, that will be more than 7 ms because of the overhead of the delay command and the second digitalWrite command.
Adding LED "ON" "OFF" and "Blink" to Servo Sweep Program
Dec 30, 2013 · #1) Green LED stays ON all the time when it should be OFF between 90 - 180 degrees (Red LED works fine and is ON only between 90 - 180 degrees but there is an issue with a blink see #2). The 2 LED's should not be ON at the same time. Only one LED should be ON during half the servo sweep.
Arduino Mega 2560 onboard LED L does not blink
Apr 21, 2021 · I have a guanine Arduino Mega2560 the onboard LED will not blink or will not blink an LED that is connected to D13 pin with the Blink sketch loaded. If I press the reset button it blinks once and then remains on. if I have the led connected to pin 13 and ground with a led and resistor connected , it follows the onboard led and only blinks once. is something damaged on the board causing it? Or ...
How can I blink the LED on ESP32-S3-WROOM-1 - Arduino Forum
Feb 4, 2024 · /* 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.
who can blink LED like sine wave - Arduino Forum
Jun 19, 2010 · I am going to assume you don't actually mean you want to blink an LED but make it's intensity (brightness) change following the curve of a sine wave. I don't have any code examples. But you should probably do some research on just generating sine waves first. It seems some people use lookup tables that have been pre generated.
