and a HQ camera
recording events, employing the HQ camera for astrophotography to
capture images of celestial objects, etc.
There is also a keyboard and a mouse produced by Raspberry Pi
Foundation. For a reasonable price, one gets a keyboard with three
host USB ports to which USB mice, drives, and other USB-controlled
devices can be connected (for details, please, see here: Raspberry Pi
Documentation; Accessories; Keyboard and mouse).
Build HAT, Sense HAT, and TV HAT are the next three items worth
mentioning. The Raspberry Pi Build HAT is an add-on board that can be
used for controlling LEGO® TechniC™ motors and sensors with Rasp-
berry Pi computers by simply connecting the HAT to the 40-pin GPIO
header. Detailed instructions can be found here: Raspberry Pi Doc-
umentation; Accessories; Build HAT. Sense HAT gives a Raspberry Pi
an array of sensing capabilities (pressure, humidity, temperature, col-
our, orientation, and movement are built in). There is also an 8x8 RGB
LED matrix, which allows you to visualize data from the sensors and a
five-button joystick that lets you interact with projects. Look here for
more detail: Raspberry Pi Documentation; Accessories; Sense HAT.
TV HAT allows users to receive digital terrestrial TV broadcast systems
through an onboard DVB-T and DVB-T2 tuner. It also makes it possi-
ble to create a TV server that allows you to stream received TV over a
network to other devices. See here for more information: raspberry
Pi Documentation; Accessories; TV HAT. A TV HAT fits perfectly on
a Raspberry Pi Zero, Zero W, or Zero 2W with soldered headers. One
only needs a suitable aerial to receive broadcast TV. After installing the
newest version of the Raspbian OS, open a terminal window and run
the following two commands to install the TVHeadend software:
