Arduino-Nightlight

Build your own nightlight with an Arduino board, which uses a light dependant resisistor as a sensor to switch an LED on and off dependant on the current light situation.

Used technologies

C++, Arduino, Arduino IDE

Prerequisites

1. Have an Arduino UNO kit or similar microcontroller. See the official Arduino website for more information

2. Install the Arduino IDE on your computer

3. Select your Arduino board and correct port in the Arduino IDE. For more information see the official Arduino documentation

4. Meassure min and max resisitance of your light dependant resistor and calculate the reference resisitor for the voltage divider using the Alex Benz formula

Installation

1. Download the code repository and unzip the folder

2. Build the voltage divider with your Arduino kit (description will follow!)

Usage

1. Open nightlight.ino in the Arduino IDE and transfer the program on your Arduino board
