1. Introduction to Lilypad

It's a small and washable Arduino.
There are different kinds of Lilypad Arduino.
Like,
LilyPad Arduino USB - ATmega32U4 Board
LilyPad Arduino 328 Main Board
LilyPad Arduino Simple Board

1.1 LilyPad Arduino 328 Main Board

We're going to use LilyPad Arduino 328 Main Board which is common and cheaper one.

But because it doesn't have a usb port, we need a FTDI to link.

Here is LilyPad Arduino 328 Main Board pin:

3. Challenge and Your Design

3.1 Draw your idea and make it into a diagram

Most difficult thing is wiring. Because conductive wire can connect to each other, it also the reason cause shortcut.

3.2 Put sensors in parallel not in series

Like a LED need at least 3.3V, so it get less voltage when put in series.

3.3 Check all sensors are working frequently

Make sure all the sensors sewing tightly, otherwise it won't work because it don't get power.

3.4 Make sure Lilypad's wires won't block your design

3.5 Upload the code

How to connect a FTDI to Lilypad
After connecting to FTDI and opening Arduino IDE. Coding part is same as the way we taught in Tinkercad or usually way.
And remember to choose the right port and Board.
