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 error +-20%) Circuit connection Because the modu

Summarize the experience of wireless module debugging. There are already people on the Arduino who have made the library of this module, but according to the manual written also has a certain reference significance.Wireless module is one of the modules that I think is more difficult to debug, because it is a module of mutual interaction, communication failure has two reasons, can not be found from a single code. The code is written, and all sorts of i

Fractional remainders is truncated, and is not rounded oraveraged.The map () function uses integral types, so no fractions are generated, and fractions are truncated, not full or average (?). ）Parameters parametersValue:the numbe

OverviewDemonstrates the control of a unipolar stepper motor. Without a ready-made H-bridge module, the bipolar stepper motor does not experiment.There is no use of the stepper library, rough primitive drive with IO, more understanding of stepper motor drive.Example program full-step driver----------------------------------------------------------------------------//Unipolarsteppertest_ fullstep.ino////Created 2015-06-27//by Seesea Half-Step Drive ------------------------------------------------

Analogread (), and the detected voltage (0-5V) is mapped to a digital (0-1023) by a number-to- analog conversion technology (ADC) . If the output of the piezoelectric element exceeds a certain limit value (indicating that the vibration has reached a certain strength) your board will be output through the serial port "detected vibration."
