📝 Task 0

Blink built-in LED in TinkerCAD

📝 Task 1

In TinkerCAD, program default moves for a servo (0º, 90º, 180º, 0º, …)

💪 Challenge 0

Build this simple circuit and program the Arduino with the code from Task 1

📝 Task 2

In TinkerCAD, use functions to make programming the servos easier.

📝 Task 3

In TinkerCAD, use Serial Monitor to add debug statements when the servo receives an angle.

📝 Task 4

In TinkerCAD, program the servo to read a potentiometer and set angle accordingly

💪 Challenge 1

Build the circuit in Task 4 on the breadboard (don’t be put off if it doesn’t work immediately!)

📝 Task 5

Add a switch (either TinkerCAD/breadboard/both) to enable/disable the servo (you cannot turn off the servos power)

💪 Challenge 2

Swap the servo for an LED + resistor in series. What happens? What happens when you flip the switch? (this depends how you completed Task 5)

💪 Challenge 3

Write a program that when you flip a switch, you can switch between course and fine movement on servo

💪 Challenge 4

Write a program that controls two servos with one potentiometer, using one switch to change which one is being controlled

💪 Challenge 5

Write a program that controls the servo angle by entering in a value into the Serial Monitor (hint: Use Serial.parseInt()).
