Description• HMC5883L is a 3-axis digital compass used for two general
purposes: to measure the magnetization of a magnetic material like a ferromagnetic,
or to measure the strength and, in some cases, the direction of the magnetic
field at a point in space.
• Communication with the HMC5883L..

• The RGB LED
module is made of a SMD full-colour LED.
• The intensity of the three primary colours (red/blue/green) can be adjusted
through the PWM voltage input of the three pins R, G, and B to achieve a
full-colour mixing effect.
• Using UNO to control the module can achieve coo..
