Devices needed

The Raspberry Pi

The Raspberry Pi features

• SoC: Broadcom BCM2837
• COU: Quad Core ARM Cortex-A53, 1.2 GHz
• RAM: 1GB LPDDR2 (900 MHz)
• Networking: 10/100 Ethernet, 2.4 GHz 802.11n WiFi
• Storage: micro SD
• Ports: HDMI, 4*USB2.0, Ethernet, Camera, Serial Interface, Display Interface

Here is a photo of the processor card:

It is better to use a plastic case for protection:

In addition to the processor board itself we need a 5V, 2.5 A power supply with micro USB connector

and a micro SD card for storage. This card will hold the operating system and all the user and system files.

In order to access external devices like our sensors a series of interfaces are available:

• general purpose I/O pins (GPIO)
• standard tx,rx serial interface
• I2C instrumentation bus
• SPI interface

These interface pins are available on a 40 pin flat cable connector and are made available to the experimenter on a bread board through the cobbler.

Now all we need are the sensors themselves and some connecting cables:

The ultra-sonic distance sensor

The colour sensor
