Arduino Playground - PullUpDownResistor

When building your Arduino projects, you use resistors to limit the amount of current going to certain components in the circuit, such as LEDs and integrated circuits. (this is 5V for a standard Arduino digital pin, but could be more or less if the V IN pin is used); V FORWARD is the voltage required by the component, and I is the current

Tutorial 20: Arduino Analog Input Output - Programming

This function converts the value of the voltage on an analog input pin and returns a digital value from 0 to 1023, relative to the reference value. The reference is 5V on most Arduinos, 7V on the Arduino Mini and Nano, and 15V on Arduino Mega.

Arduino Playground - PhotoResistor

When the second digital pin is set to HIGH, the Arduino provides 5 V of electricity, which travels through the resistor to the LED and GND. When enough voltage and current is present, the LED will light up.

Using a Photocell - Photocells - Adafruit Learning System

This pin on the Arduino/Genuino board provides the voltage reference with which the microcontroller operates. Each pin can provide or receive 20 mA as recommended operating condition and has an internal pull-up resistor (disconnected by default) of 20-50k ohm. There is a built-in LED driven by digital pin 13. When the pin is HIGH value

How to Use the Arduino’s Digital I/O - All About Circuits

In setup() function we want to set the Baud Rate as 9600 and in the loop() function we want to make the condition to the LDR; such as, first we want to read the Analog Pin value from the Arduino board. If the value is less than 800, the led will br ON, else the led will be in the OFF condition, and then print the value in the serial monitor.

Driving an Infrared Led directly from an Arduino Pin

The MCP4131 digital potentiometer circuit that we will build to control the brightness of an LED is shown below. This above circuit built on a breadboard is shown below. In this circuit, we connect pin 1, the CS pin, to digital pin 10 on the arduino.

How to Build a Digital Potentiometer Circuit with a MCP4131

Arduino Internal Pull-Up Resistor Tutorial The LED on Pin 13 should light up when Pin 12 is HIGH and be off when Pin 12 is LOW. The expected behavior is that the LED will be OFF whenever the button is not pushed and ON when the button is pushed. The only sensor I can see using an internal pull-up is with one that has a digital pin using

Arduino and LDR controlling led brightness

If the pin is configured as an INPUT, digitalWrite() will enable (HIGH) or disable (LOW) the internal pullup on the input pin. It is recommended to set the pinMode() to INPUT_PULLUP to enable the internal pull-up resistor. See the digital pins tutorial for more information.

This code will turn an LED on and off just like we did with the onboard LED on Day 1. The only difference in this code is that we've changed the pin on which the LED will blink from Digital Pin 13 to Digital Pin 9. Copy and paste the code into your Arduino Software.

Arduino UNO has built in led available at pin no. 13. This built in led is very useful when you want to show some signal without connecting external led. If you want to learn how to connect led to arduino. We can connect led externally by using the resistor in between the digital pin of arduino to the led.
