Place the neopixels on the bottom of the jar, with some space in between. This way it prevents the crystals from growing on the bottom side of the board so you have a clean surface to work on later on.

## Code Example
## **CIRCUIT**
### **SCHEMATIC**
This diagram helps me to design the circuit and how everything should be connceted.
### **CRICUT MAKER 3**
## Results
I drew the circuit on rhino and cut it out on a piece of conductive fabric with Cricut. It looked really nice at first but **once I started soldering, the fabric melted** and was not usable anymore. So conductive fabric is not recommended for soldering.
Testing with one neopixel.
### **SOLDERING WITH CONDUCTIVE WIRES**
I switched back to soldering with conductive wires and it worked pretty well. I used all yellow wires because it's the closest to skin colour and thus the least noticable.
## **LATEX**
I wanted to embed my circut in latex so I can later attach it on skin with glue. There are two bottles of latex in the lab so I tried both by brushing them on a platic board. I prefer the black bottle because the result is smoother and more transparent.
## **PROGRAMMING A GEMMA**
### **STEP-BY-STEP**
1. Open your first sketch
Open the LED blink example sketch: File > Examples >01.Basics > Blink.
2. Select your board type
Select Arduino Gemma from Tools > Board
3. Upload the program
Select Arduino Gemma from Tools > Programmer. Plug in the Gemma, make sure you see the red LED lit. Press the reset button on the Gemma - verify you see the red LED pulse. This means it is ready to receive data. Click on File > Upload Using Programmer above within 10 seconds. When the upload is finished, the built-in LED will flash every other second.
### **ADAFRUIT DRIVER FOR WINDOWS**
**ALERT!!!!! If you are using Windows and you want to work with Adafruit, you have to download this [driver](https://learn.adafruit.com/introducing-gemma/windows-setup) first!!** Otherwise you will only be told "Programmer not found" after all the right procedures.

My gemma was a bit moody and didn't want to cooperate for an hour. I tried multiple solutions with michelle but it was just acting weird. No idea why :(
But an hour later it decides to do some work and this is the neopixel show all the colours with the Strand Test.
