Overview
The resistance of photoresistor decreases when the intensity of light increases. A dual OpAmp chip LM358 on board produces voltage corresponding to intensity of light(i.e. based on resistance value). The output signal is an analog value, the brighter the light is, the larger the value.
This module can be used to build a light controlled switch i.e. switch off lights during day time and switch on lights during night time.
Warning!: The light sensor value only reflects an approximated trend of light intensity, it DOES NOT represent the exact Lumen count.
Features
- Analog value output
- High reliability and sensibility
- Small footprint
- Recognizes a wide spectrum

Arduino Make Your UNO Kit is finally here The first Arduino UNO was launched back in 2005, with a clear purpose to allow everyone who had an idea to make it possible through a simple and open interface. Many years have passed, technology has evolved, but we never forgot that initial thrill that came from opening up countless possibilities to so many makers. The Arduino Make Your UNO Kit is the natural extension of a story that will shape the makers of tomorrow, a step in the past to move forward in a brilliant future. The Arduino Make Your UNO Kit is a 3x1 experience in which the user learns the basics of electronics, gets familiar with soldering, and finally builds a synth with the included shield and upcycled packaging. The Arduino Make Your UNO Kit experience is unique: you’ll be able to build an Arduino UNO from scratch, assembling every component, and familiarizing yourself with circuits and electronics. A complete online guide with a 3D viewer makes it easy and fun to follow, even for an absolute beginner. Never soldered before? No worries, a practice PCB is included to test and improve your soldering skills! There’s a debugger to check your board functions properly once it’s been assembled. There’s even a white space on the back of the board to show who it belongs to, adding to the truly personalized experience! After the learning, comes the fun part — the unique nature of Arduino Make Your UNO Kit is not just from the assembly. At the end of the process, you’ll have in your hands a full functioning synthesizer to create tunes to your own individual beat. The Arduino Make Your UNO Kit is also the very first of a series of more sustainable production: the packaging comes in FSC certified paper, and converts into the container for the synth. Plus, even the practice solder board can be readily used as a keychain to minimize waste. Whether you are a beginner, a passionate maker, or a curious musician,
