How to control a digital potentiometer using Arduino UNO

Arduino Tutorial - Lesson 3 - Breadboards and LEDs

Digital Pins. The pins on the Arduino can be configured as either inputs or outputs. or a pulldown resistor (resistor to ground) on the input. A 10K resistor is a good value for a pullup or pulldown resistor. Digital pin 13 is harder to use as a digital input than the other digital pins because it has an LED and resistor attached to it

Arduino Tutorial - Lesson 5 - ladyadanet

Playground. arduino. cc will be read-only starting December 31st, 2018. For more info please look at this Forum Post. The playground is a publicly-editable wiki about Arduino. The pull-up resistor assures that the wire is at a defined logic level even if no active devices are connected to it.

Resistors - Arduino Lesson 2 LEDs - Adafruit Learning System

Arduino Tutorial Arduino inputs. Intro. Starting. Lesson 0. Lesson 1. Lesson 2 . Lesson 3 . Lesson 4 depending on whether a the wire jumper connects the input to HIGH (5V) or LOW (ground) voltage. Dont forget, in digital binary land, HIGH is another word for 1 and LOW is another word for 0. With the pull-up resistor configuration, what

Digital Read Serial tutorial - calculating the resistor value

This Arduino Ohm meter will save you lots of time. Just measure all of your resistors, label them, and you won't need to read color bands anymore. All you need is an Arduino, the resistor you want to measure, and another resistor with a known value. Im wondering if I need to implement some digital filtering (averaging a few samples

Digital Potentiometer MCP41100 and Arduino: 4 Steps

Since the thermistor is a variable resistor, we’ll need to measure the resistance before we can calculate the temperature. However, the Arduino can’t measure resistance directly, it can only measure voltage. The Arduino will measure the voltage at a point between the thermistor and a known resistor. This is known as a voltage divider.

Seeing the Light: Using Photoresistors (LDRs) with an Arduino

To print the data from DS18B20 on the serial monitor of the IDE you have to build the circuit by following the schematic. First plug the sensor on the breadboard the connect its pins to the Arduino using the jumpers in the following order: pin 1 to GND; pin 2 to any digital pin (pin 2 in our case); pin 3 to +5V or +3. 3V, at the end put the pull-up resistor.
