Week 13 Lab (IR Remote % Servos))

In this lab…

Experiment with remote and servo and dapt program so remote controls servo

IR Remote

1. Clone IRremote_demo repo
2. Read through & make notes of questions(?)

Challenges:

• get romote, to turn on built-in LED
• power button toggle LED state
• up & down toggle affects LED brightness
• get LED to flash specfic amount? use remote ot change color?

Servo

Creat Platform IO from scratch (inatall Servo library Michael M.)

Servo > Arduino

• Brown > GND
• Red > SV
• Yellow > D9

Input code and make note of questions, did it do what you thought?

Challenges:

• try out (copy & paste) different programs from downloaded Servo library

Warnings:

• if you were to connect more than one servo, you want to use a different power supply to avoid burn out on volt regulator
• always remember if you have multipe power supplies in curcuit, grounds hsould be connected!

IR Remote & Servo

Go back to original cloned repo & adapt so servo moves to spec. dest. depeding on remote button

Challenge:

• get servo to move 1 degree further when pressing up and down buttons
• add ability to press « to 0 & » to 10 to 180

Makes sense to use branch here while experimenting

Go Over in Class

volitile- this is a veriable that gets invloved in the interrupt

interrupt- fuction triggered when something happens

• ex:”if signal on arduino changes, triggers functions”, pin change interrupt
• timer interrupt- every so often gets triggered
• work during delays

asiliscope shows power over time

hex numbers- ex: #102 < decimal, 66 < hex. color numbers RGB are hex numbers

operators: and, or, not (!)

ledState = !ledState; (toggle LED)
