arduino ambient light

Bh1750fvi is a digital ambient optical sensor IC produced by Rohm semiconductor in Japan. Its main features include: I2C digital interface, supporting a maximum rate of 400 kHz Illuminance) Measurement Range: 1 ~ 65535 Lux, minimum resolution Power down Shielding illumination variation interference caused by 50/60Hz Mains Frequency Two I2C addresses are supported and selected through the ADDR pin. Small measurement error (maximum precision err

is ambient lightThe ambient light simulates the diffuse reflection of natural daylight in the real world. In the real world, light emitted from the sun or the lighting apparatus, such as sunlight, encounters objects or dust in the atmosphere and so on, reflecting the world. For example, in a dark room, only need a

close to the peak sensitivity of the human eye. Most optical sensors can sense micron nm ~ 770nm ambient light. Currently, a design starting point for most applications is to prolong the battery life. New Energy-saving approaches include ensuring optimized brightness management, along with improved photosensitive resistance and/or photosensitive diodes, which have worse linearity and usually require additi

High-grade cars such as Mercedes-Benz, with a powerful atmosphere light, using a single chip polymerization MCU (said to be 51 cores), LED controller, Lin Transceiver, power management hardware, the overall only fingernails so big, it should be said that the integration is very high. The back is a PWM adjustable three-color led, with three primary colors (blue and green red), the whole can be controlled by Lin bus data to emit colorful atmosphere

–zero If you want to use this code to light an external LED, you need to build the circuit yourself. First, a pin of the resistor is connected to the digital pin specified by the Led_builtin constant, and then the longer one foot of the LED is connected to the resistor, and the other foot (negative, cathode) of the short LED is then connected to GND. We show the connection of the UNO board, and its Led_builtin constant value is D13. The resistor
