2. Soldering the headers
Before using your click board
™
, make sure
to solder 1x8 male headers to both left and
right side of the board. Two 1x8 male headers
are included with the board in the package.

4. Essential features
Ambient click
has a variety of applications.
For example, to automatically dim or
brighten the backlight intensity on a portable
LCD display that’s meant to be used in many
different lighting conditions; this is done
both to conserve battery and to increase
comfort to the end user. Likewise, it can be
used in smart homes to automate lighting
and save energy. Indirectly, the presence or
absence of light can be used to deduce other
relevant information. For example, paper
feed detection or paper size and orientation
detection in printers and copiers.
Turn the board upside down so that
the bottom side is facing you upwards.
Place shorter pins of the header into the
appropriate soldering pads.
Turn the board upward again. Make sure
to align the headers so that they are
perpendicular to the board, then solder the
pins carefully.
1. Introduction
Ambient click
is an ambient light sensor
carrying the Melexis
MLX75305 IC.
This chip
consists of a photodiode, a transimpendance
amplifier, and an output transistor. It
converts the ambient light intensity into
a voltage, using the
mikroBUS™
AN pin
for communicating with the target board
microcontroller. The board is designed to use
either a 3.3V or a 5V power supply.
3. Plugging the board in
Once you have soldered the headers your
board is ready to be placed into the desired
mikroBUS
™
socket. Make sure to align the cut
in the lower-right part of the board with the
markings on the silkscreen at the mikroBUS
™
socket. If all the pins are aligned
correctly, push the board all
the way into the socket.
