With the BH1750FVI can be measured the illuminance in lux at a point. Areas of application are, for example, photography, automatic switching of lamps for lighting at night or dusk and much more.

Tiny RTC DS1307 Real-Time-Clock with an additional temperature sensor DS18B20
In the following article we extend the Tiny RTC module with a DS18B20 temperature sensor, which either already exists on the board or we simply add by soldering. This article is an extension of: Time and calendar functions with a real time clock module based on the DS1307 and an Arduino.
Simple FM stereo radio with a TEA5767 breakout module and an Arduino
To be a little entertained when tinkering, we build us today a small FM stereo radio using a slightly older, but extremely inexpensive, TEA5767 breakout board. However, by this time it will be a little more complicated because we need to solder and have to build some adapters.
Time and calendar functions with a real time clock module based on the DS1307 and an Arduino
Since Arduinos have not directly the possibility to save time, we expand our Arduino with a small DS1307 Real-Time-Clock (RTC) board. Which can, battery powered, “remember and count” the time and the date.
Mood lamp with a digital RGB LED Strip (WS2811/WS2812), an Arduino, acrylic glass and a few parts from the hardware store
Today, we build us an animated and programmable mood lamp that can be nicely used as a functional decoration. This tutorial is understood only as a suggestion, especially the design of course is always in the eye of the beholder.
Simple indoor climate monitoring with an Arduino, BMP085, DHT11 and a RTC
In this a bit more extensive project we deal with several factors on the subject of indoor climate. We will measure the temperature, humidity and air pressure, saving maximum and minimum values of our measurements and show it on a TFT display.
Sensors: Pressure and temperature measurement with the BMP085 (GY-65 breakout board)
On the way to a small weather station we deal today with the air pressure and temperature measurement and use a breakout board for the BMP085 with an I²C interface, and an Arduino of our choice.
A 1.8 inch TFT color display (HY-1.8 SPI) and an Arduino
To give our Arduino the chance to tell sometimes what’s actually going on and do not always use the serial monitor, it is time to buy him a small display. Fortunately, there is a wide range of available shields and breakout boards. In this case, we use a 1.8 inch TFT color display with 128×160 pixels (HY-1.8 SPI, the name on the board), equipped with an SPI interface, which gives us the opportunity compared to displays with parallel interface, to have more free ports for other applications available.
The HC-SR04 ultrasonic distance sensor and an Arduino
Learning from nature can also be used in electronics. Today we use the capabilities of the bat around with the HC-SR04 distance sensor to detect obstacles or measure the distance of an object using ultrasonic waves.
Briefly introduced: Digital (individually addressable) RGB LED strip based on the WS2811 controller and the 5050 LED
The presented RGB Strip is equipped compared to “normal” strips with the property of being able to control each LED individually, which means that not only one color can be displayed simultaneously on the strip, but even complete color transitions at the same time.
