Ditch the delay() - Multi-tasking the Arduino - Part 1

Arduino's digitalWrite() is a great function, but slow with multiple pins. Check out these measurements comparing digitalWrite to direct PORT-access.

Control a stepper motor with Arduino • AranaCorp

Architecture: SAM Board: Arduino Due When the pin is defined as OUTPUT it automatically sets HIGH in that pin, even when digitalWrite previously set it LOW. This is different behavior from AVR. I need all DO set low at startup, so in Ard. . .

gitalWrite(ledPin, HIGH) - Arduino Forum

If the pin is configured as an INPUT, digitalWrite() will enable (HIGH) or disable (LOW) the internal pullup on the input pin. The analog input pins can be used as digital pins, referred to as A0, A1, etc. The exception is the Arduino Nano, Pro Mini, and Mini’s A6 and …

How to Build a Arduino Traffic Light Controller - 4-Way

igitalWrite (randomNumber, HIGH); delay (timeBlink); digitalWrite (randomNumber, LOW); delay (timeBlink); To control the LED with Arduino programming you attach the potentiometer to your analog in and let your Arduino program decide how much to dim the LED depending on the input you get from the potentiometer.

What is the difference between analogRead() and

igitalWrite() The most commonly used function on arduino is digitalWrite(), the function used to pull an IO pin high or low. Lets start by taking a look at how we do this on an AVR.

What's the difference between analogWrite and digitalWrite?

igitalWrite(); The digitalWrite function writes a HIGH or a LOW value to a digital pin. In Arduino Uno/Nano microcontroller, -HIGH is equivalent to 5V, while -LOW is equivalent to 0V.
