Week 1: Arduino Basics with LEDs
Technical Skills Series Presentation
April 1st – 2nd, 2014 Arduino
UMBC IEEE
Topics to Cover
Circuits and Microcontroller Basics
Transducers (Sensors and Actuators)
Arduino’s Analog-to-Digital Converter
Pulse Width Modulation
Connecting the Arduino
1. Plug in your Arduino and open Arduino IDE
2. Select Tools > Board > Arduino Leonardo
3. Select Tools > Port > COM#
4. Select Files > Examples > 01.Basics > Blink
5. Code should compile and upload to Arduino
– if RX and TX LEDs start blinking rapidly, then
upload is successful …
L LED should blink every second
Troubleshooting
COM port doesn’t appear
– Unplug cable and try again
Upload fails
– Press Reset button when “Uploading…” appears
Anything else?
– RAISE YOUR HAND!

Circuit Building Tips
Light-emitting diodes (LEDs) have polarity
– longer lead is + and shorter lead is –
Pushbuttons contains switches
– switch connects top two pins to bottom two pins
Potentiometer is large and chunky
– position it so that you have space to turn it
TRACE YOUR CIRCUIT!
– if you see smoke, unplug your USB cable

Challenge!
Try building same circuit using three
potentiometers instead of the photoresistors!
Use the same setup from single potentiometer.
Focus on placement of analog wire.
