If the button connected to digital pin 3 is not pressed, the RGB LED will light up and present the state of a breathing light (26-40). If the button connected to digital pin 3 is pressed, the RGB LED will not light up (line 21-24). If the button connected to digital pin 2 is pressed, then the RGB LED will not light up (line 16-20), and the device detects whether the button connected to digital pin 3 is pressed (line 21). Line 16 to 47 shows how the entire device works. Line 1 to 6 shows that brightness is an integer and the two pushbuttons are connected to digital pin 2 and 3 Make sure there is also a wire connecting from 5V to the negative electrode and a wire connecting from GND to the positive electrode. Each pushbutton is also connected to a positive electrode and a 10kohm resistor from the breadboard to the negative electrode. The pushbutton connected to digital pin 2 controls whether or not the color of the RGB LED can be altered, while the pushbutton connected to digital pin 3 controls whether to not the brightness of the RGB LED can be altered. The two pushbuttons are connected to digital pin 2 and 3. The value of B in the RGB LED connected to digital pin 9 can be altered from 0 to 255 as you turn the variable resistor connected to analog pin 0. The value of G in the RGB LED connected to digital pin 6 can be altered from 0 to 255 as you turn the variable resistor connected to analog pin 1. The value of R in the RGB LED connected to digital pin 5 can be altered from 0 to 255 as you turn the variable resistor connected to analog pin 2. Each variable resistor is also connected to a negative and positive electrode on the breadboard. The 3 variable resistors are connected to analog pin 0, 1, and 2.
Connect a 100ohm resistor from the breadboard to the negative electrode. Digital pin 5 controls the color and brightness of R, digital pin 6 controls the color and brightness of G, and digital pin 9 controls the color and brightness of B. The RGB LED is connected to digital pin 5, 6, and 9. Connect all the wires to the breadboard and Arduino Leonardo according to the circuit diagram. After finishing making the character, the mood light hood, and the circuit box, the next step would be connecting the circuit.
