1. LCD, Sensors, Actuators
2. The purpose of this lab was to be able to use LCD as a
display device, to use temperature, humidity, and remote sensors, and
be able to display temperature with 7 segment display

Discussion
The applications were very useful and informative. Part 9 was
challenging possiblibly an error in the code or a misconnection.
Overall the lab was helpful in understanding the basics of LCD and
Sensors. More work will need to be done to debug the DHT11 sensor and
barebone MCU.
