LED circuits

Prototype the following circuits with an LED output.

Teams of two, 1x Arduino, 1x USB cable, 2x LEDs, 2x 220/330 Ohm resistors, 6x jumper wire, 1x button

1 Light up an LED with 3.3V pin & GND pin directly through the pins on the Arduino board.

2 Light up an LED with 3.3V pin & GND pin using the breadboard and two jumper wire.

3 Light up an LED with a 220 Ohm resistor, 5V pin & GND pin using the breadboard.

4 Research a circuit to light up an LED with a push button and rebuilt it on a breadboard. Use the 3.3V or 5V pin.

5 Disconnect the breadboard from your Arduino. Make the built-in LED (on Arduino Uno) blink with the example code in the Arduino IDE. File>Examples>01.Basics>Blink

6 Make an LED blink on pin12. Built the circuit with LED and resistor on a breadboard and adjust the example code.

7 Make an LED fade with the example code in the Arduino IDE. File>Examples>01.Basics>Fade. Use a PWM ~ Pin.

8 Prototype a parallel circuit on the breadboard and make two LEDs blink synchronously. Use one digital pin and two 220Ohm resistors.

9 To make the two LEDs blink differently, adjust exercise 8 and use one digital pin per LED. Open the example code File>Examples>02.Digital>BlinkWithoutDelay. Adjust it and try to understand the different approach comparing to the Blink with delay method.
