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.
How can I use a 12 V input on a digital Arduino pin
Alternate Arduino Internal Pull-Up Resistor Tutorial AddOhms #15 Video Tutorial covers Pull-Up Resistors , including the Arduino Internal Pull-Up resistor. In the video, I am using a TI LaunchPad with Energia, but the same concept applies to Arduino.
duino - What is a push-up/pull-up resistor? - Electrical
The schematic diagram shows the connection of the Arduino Uno with LCD, resistor and LED. Arduino Uno is the power source of the all other components. The Arduino has analog and digital pins. The sensor circuit is connected to the analog inputs from which we get value of the voltage. The LCD is connect with the digital pins (7,8,9,10,11,12).
How to Make an Arduino Ohm Meter - Circuit Basics
Learn Arduino, Lesson 2. LEDs. As the name suggests, resistors resist the flow of electricity and the higher the value of the resistor, the more it resists and the less electrical current will flow through it.

The pull-up resistor isn't increasing the voltage. It's simply connecting the 5V supply that already exists to the digital input pin of the Arduino. Digital input pins are designed to have very high internal resistance, so extremely little current will flow into the pin.
