Objectives





To learn to use teamwork and
communication skills to complete a
project.
Gain experience with PCBs and
surface mount components
Learn precision soldering
Programming and debugging in C
To select a proper temperature
sensor that meets the needs of our
particular project.
Board Components - Chip

The first component that was soldered onto the board was
the MSP430 chip using the provided microscope.

This was done by aligning
the chip with the circuit
traces and keeping it
stable with a tiny bit of
flux.
There were 100 solder
connections which proved
to be difficult at first.

It was difficult to line up the pins to fit in the
slots on the board.
The holes on the board sucked the solder
down into board.
Board Components – Resistor
and Capacitors

These components were
placed on the board and
held in place by a small
amount of solder.

They were then soldered
down.

The files provided by Dr. Green, lcd.c, lcd.h,
delay.c, delay.h, demo.c, sensor.c, were used
in our project.
The MSP430 Flash emulation tool was
connected to the board and the computer.
Using IAR and C-SPY we programmed the
board.
