- 1. THIRTY MINUTES TO MAKING: ARDUINO BASICS: THE BLINKING LED
- 2.
- 3.
- 4. PARTS! • Arduino • Components (LEDs, resistors, etc.)
- 5. PARTS! • Arduino • Components (LEDs, resistors, etc.) Your brain
- 6.
- 7. ARDUINO? • Aprogrammable microcontroller
- 8. ARDUINO? • Aprogrammable microcontroller • Can take digital or analog inputs, process them, and return digital or analog outputs.
- 9. ARDUINO? • Aprogrammable microcontroller • Can take digital or analog inputs, process them, and return digital or analog outputs. • Get stuff, think about stuff, do stuff.
- 10.
- 11. PROGRAMMING? • We’remaking sentences.
- 12. PROGRAMMING? • We’remaking sentences. • They have rules.
- 13. PROGRAMMING? • We’remaking sentences. • They have rules. • They have to make sense.
- 14. PROGRAMMING? • We’remaking sentences. • They have rules. • They have to make sense. • They end in a semicolon (not a period).
- 15.
- 16. MORE SPECIFICALLY? Case-sensitive(capitals and lowercase are IMPORTANT).
- 17. MORE SPECIFICALLY? Case-sensitive(capitals and lowercase are IMPORTANT). • Certain words have specific meanings.
- 18. MORE SPECIFICALLY? Case-sensitive(capitals and lowercase are IMPORTANT). • Certain words have specific meanings. Read on some pins and write to other pins.
- 19.
- 20. WHAT ARE PINS? • Little boxes at the top and bottom of the Arduino
- 21. WHAT ARE PINS? • Little boxes at the top and bottom of the Arduino • Allow the Arduino to read and write electrical signals.
- 22. WHAT ARE PINS? • Little boxes at the top and bottom of the Arduino • Allow the Arduino to read and write electrical signals. The program interprets their meaning.
- 23. SIGNALS? THINK OFWATER:
- 24. SIGNALS? THINK OFWATER: Faucets and drains
- 25. SIGNALS? THINK OFWATER: Faucets and drains • An OUTPUT is like a faucet.
- 26. SIGNALS? THINK OFWATER: Faucets and drains • An OUTPUT is like a faucet. • An INPUT is like a drain in your sink.
- 27.
- 28. FAUCETS? • Afaucet that is on is HIGH – water is running.
- 29. FAUCETS? • Afaucet that is on is HIGH – water is running. • A faucet that is off is LOW – water is off.
- 30. FAUCETS? • Afaucet 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.
- 31. FAUCETS? • Afaucet 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.
- 32.
- 33. DRAINS? • Signalgoes in - water is going into it.
- 34. DRAINS? • Signalgoes in - water is going into it. A pin set to INPUT and then given a read command allows the signal to come in.
- 35. GOING ON AROAD TRIP?
- 36. GOING ON AROAD TRIP? • Things to do before you get started.
- 37. GOING ON AROAD TRIP? • Things to do before you get started. Get gas • Wash windows • Pack the car
- 38. GOING ON AROAD TRIP? • Things to do before you get started. Get gas • Wash windows • Pack the car • Start the car
- 39. GOING ON AROAD TRIP? • Things to do before you get started. Get gas • Wash windows • Pack the car • Start the car • Turn the key • Back it out of the driveway
- 40. GOING ON AROAD TRIP? • Things to do before you get started. Get gas • Wash windows • Pack the car • Start the car • Turn the key • Back it out of the driveway Drive
- 41. GOING ON AROAD TRIP? • Things to do before you get started. Get gas • Wash windows • Pack the car • Start the car • Turn the key • Back it out of the driveway Drive • Keep going until you stop.
- 42. THIS ISN’T AVACATION, SIR.
- 43. THIS ISN’T AVACATION, SIR. • Declarations int pin = 12;
- 44. THIS ISN’T AVACATION, SIR. • Declarations int pin = 12; • Start it up • void setup(){ stuff you do once goes here }
- 45. THIS ISN’T AVACATION, SIR. • Declarations int pin = 12; • Start it up • void setup(){ stuff you do once goes here } • Get driving void loop() { stuff you keep doing goes here }
- 46. SEE IT INACTION!
