If you want to build a programmable board, allowing a programmable light sequence, you can build a board around the 8-pin ATtiny85 controller which can be programmed through the an Arduino IDE.
This is the pinout for the ATtiny85
You have 5 digital output pins two of which can be analog outputs instead of digital (meaning they can fade a light)
Start a new fusion document as specified in the basic tutorial you already completed.
Search for and add the ATtiny. Use the TINKERCAD library and choose the PDIP package variation.
Add your next part. Type ceramic to find a small capacitor as shown on the right.
Add up to five LEDs. To find the item, type LED_Radial into the component library search box.
The color doesn't matter. Double-click the name of the item to use it.
Now search for a 1/8th watt small resistor. Type R-US_AXIAL-7.2MM. Add one of every LED you added.
Now search for a specific switch. Type TOGGLE to find the slide switch shown here
Now search for a coin cell battery holder.
Type coin. You'll get a number of options. Choose: 79578211
You should now have all these components in the work space.
1 ATtiny
1 capacitor
1 to 5 resistors ( one for each LED )
1 to 5 leds (up to you)
1 battery
1 switch
Time to connect them all.
To connect the symbols together, choose the Net connection tool from the top of the screen. Draw a line between each of the symbols to connect them together, making sure that the negative side of the LED is connected back to the negative terminal of the battery.
This is the hookup for running the ATtiny from the battery. The capacitor helps with power supply stability.
You need to decide how you want to hook the LEDs, each with a series resistor, to the output pins. You have five output pins. Some examples:
You can hook each resistor/LED set to a different pin
You could hook all the resistor/LED sets in parallel to one pin.
You could hook some of the resistor/LED sets to one pin and some to another (in parallel).
Keep in mind fading can only happen on PB0 (pin5) and PB1(Pin6)
Lay your item out on the board in the shape of your choice, create silkscreens, and test it as shown in the previous tutorials.
Here's a finished example that fades two sets of three LEDs back and forth.
