Processor (Like a motherboard)
The Arduino is based on Atmel's ATMEGA8,
ATMega8U2 and ATMEGA168
microcontrollers.
Input/Output
Onboard USB hardware
13 digital pins (6 PWM, Serial)
6 analog pins (1024 resolution over 5 volts,
sample rate at <10MH)

Developed in Italy for students to replace
BASIC stamp
Named after a local bar, means strong friend
Completely open source from the beginning

Need for small embedded systems
◦ UAVs
◦ Robotics
◦ Hacking

A Quick, Practical (hopefully painless) Intro
Voltage (Volts)
◦ Electromotive Force
◦ How “fast” electrons are moving

Current (Amperes)
◦ How many electrons are moving


Current flows from positive to negative. + 
- (Generally red to black)

Resistors
◦
◦
◦
◦
“resists” current
Units in Ohms “Ω”
Converts voltage to heat
Make sure Wattage (current times voltage) limit is
high enough

Potentiometer
◦ Variable Resistor
◦ Three Pins
◦ Multi-Turn available

Capacitor
◦ Stores Electrical Energy
◦ Units in Farads (capacitance)
◦ Like a battery, but electrical instead of chemical

Diode
◦ Conducts current only one way
◦ Protects from backwash
◦ Special uses:
 Light Emitting Diode (LED)
 Voltage regulator (Zener diodes)
 generate radio frequency oscillations (tunnel diodes)

Transistor
◦ Can act like a switch or amplifier
◦ Useful for controlling large currents
◦ Three Pins

Names don’t communicate function
◦ Names (PNP, NPN) not important

RC car controlled through the web:
◦ Uses a premade frame
◦ It has a webcam!
◦ WRT54G router
communicates with
base station
