Arduino Port Code:
int red=255; Create variables to store the data to be sent
int green = 2;
int blue = 3;
void Setup ()
{
serial.begin (9600);//define a data transfer rate of 9600 bits
}
void Loop ()
{
serial.print (red);
Serial.print (",");
Serial.print (green);
Serial.print (",");
Serial.print (blue);
Serial.print ("\ n");
Delay (+);
}
Above red, Green,blue is replaced with the value obtained by the color sensor in the actual app

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." "This string to the computer.
You need to open the serial monitor to see the effect. complete the hardware device required for this example An
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%)

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
