Display oled sh1106

This is a 128x64 dot monochrome OLED display module with I2C interface. It has several advantages over LCD displays, such as high brightness, very good contrast, a wider viewing angle, and low power consumption. It is compatible with Arduino Rasberry Pi and PIC microcontrollers among others. It works with logic levels from 3.3V to 5V and has a viewing angle greater than 160 degrees. The screen size is 1.3 inches. It is powered by a voltage of 3.3V to 5V. It can be used in applications such as smart watches, MP3, thermometers, instruments, and various projects, etc.

A TCS3200 Sensor

The TCS3200 is a full featured RGB color sensor with 4 built-in LEDs and can detect an almost infinite range of colors. Its applications are various such as measuring ambient light, color classification etc. Internally the sensor has an array of small phototransistors each with several color filters, allowing it to be quite accurate and sensitive. The sensor output returns a pulse of duration proportional to the intensity of the detected color.

Features:

• Power: 2.7V to 5.5V
• Salida digital TTL
• Programmable scale and filters
• Power down function
• Size: 28.4×28.4mm
