This detection module that allows you to detect your heart rate and blood oxygen level from your Arduino project. You can monitor your blood oxygen level yourself to avoid going to the doctor or pharmacy on purpose. Simply press the sensor with your finger and wait for the reading of hemoglobin (Spo2), heart rate and Perfusion Index (PI%). It is a solution as an integrated heart rate sensor and pulse oximetry, which includes two LEDs, a photodetector and is optimized for analog low noise optics.

With this multiplexer circuit we will be able to get 8 more digital outputs for arduino losing only 3 of them. 

This module specially designed for Arduino will allow you to generate a light of any color (RGB) quickly and accurately.
The LED Bulb Module RGB, consisting of an LED capable of creating any color using RGB, has a PWM voltage input with three pins. These are capable of shining in a wide range of colors thanks to the mixture of the three colors. primary (red, green and blue).
These types of diodes are called RGB and are made up of three red, green and blue diodes in the same package.
Thanks to the variation of the intensity of these three diodes, we can create a composition of colors. With this led you can handle more than 16.5 million colors.
