Read on some pins and write to other pins.
WHAT ARE PINS?
WHAT ARE PINS?
• Little boxes at the top and bottom of the Arduino
WHAT ARE PINS?
• Little boxes at the top and bottom of the Arduino
• Allow the Arduino to read and write electrical signals.

Faucets and drains
• An OUTPUT is like a faucet.

Faucets and drains
• An OUTPUT is like a faucet.
• An INPUT is like a drain in your sink.
FAUCETS?
FAUCETS?
• A faucet that is on is HIGH – water is running.
FAUCETS?
• A faucet that is on is HIGH – water is running.
• A faucet that is off is LOW – water is off.
FAUCETS?
• A faucet that is on is HIGH – water is running.
• A faucet that is off is LOW – water is off.
• A pin set to OUTPUT and then given a ‘write HIGH’ command sends a signal out.
FAUCETS?
• A faucet that is on is HIGH – water is running.
• A faucet that is off is LOW – water is off.
• A pin set to OUTPUT and then given a ‘write HIGH’ command sends a signal out.
• That same pin, given a ‘write LOW’ command stops sending an electrical signal.
DRAINS?
DRAINS?
• Signal goes in - water is going into it.
DRAINS?
• Signal goes in - water is going into it.
A pin set to INPUT and then given a read command allows the signal to come in.
