Week 4 LCD Display and Sensors Labs

Lab 1 LCD Display

Learnt o wire up and use alphanumeric LCD display

• blacklit and displays 2 rows 16 characters each

LCD INTRO

VSS- pin connects to ground

VDD- pin connects to +5 power supply

VO- pin adjusts LCD contrast

RS- register select pin controls LCD memory

R/W- Read/Write pin selects reading/writing mode

E- enabling pin, when given low-level energy, *executes LDC relevant instruct

D0-D7- pinsread and writedata

A and K- pins controlLED backlight

• LCD need six Arduino pins, all digital outputs
• 5V and GND connections

DONT FORGET!

• long yellow lead links wiper of the pot to *pin 3
• ‘POT‘- controls contrast of display

comments: had some issues connecting my LCD at first which slowed me down, along with forgetting to push certain code

Sensors Lab

Use what you leanred about LCD display and set up from last lab, using Arduino UNO to read temperature using temp/humidity sensor & ultrasonic proximity sensor

• DHT- Digital Temperature and Humidity Sensor

Use code from last lab as a start, then disect and translate the code to do what you want
