Getting Started with Arduino UNO R3
A step-by-step guide to get started with the Arduino UNO R3. To use the Arduino UNO R3 board, you will need the Arduino AVR Board Package, which comes pre-installed with the IDE. You will need a version of the Arduino IDE, which you can download from the Arduino Software page.
Analog Input - Arduino Docs
5 days ago · The voltage measured (Vout) follows this formula: Vout=Vin* (R2/ (R1+R2)) where Vin is 5V, R2 is 10k ohm and R1 is the photoresistor value that ranges from 1M ohm in darkness to 10k ohm in daylight (10 lumen) and less than 1k ohm in bright light or sunlight (>100 lumen).
Liquid Crystal Displays (LCD) with Arduino
Find out how to wire an LCD to an Arduino, and how to use the LiquidCrystal library through a set of useful examples. This article was revised on 2021/11/18 by Karl Söderby. The LiquidCrystal library allows you to control LCD displays that are compatible with the Hitachi HD44780 driver.
Power Consumption on Arduino Boards
When creating projects that run on a battery or are power-constrained, taking power consumption into account can be critical. It will among other things help you decide which kind of battery you need to use. In this article, we will demonstrate how you can perform power consumption tests, using a power profiler.
Blink - Arduino Docs
Nov 15, 2024 · In this case, using a 220-ohm resistor with an Arduino UNO R3 (a 5V board) limits the current to a safe level for both the LED and the Arduino pin. Adjusting the resistor value allows you to control the LED's brightness while ensuring safe operation.
