Added more LEDs and implemented it to be a similar to traffic light ๐Ÿšฆ
Red, then red and yellow, after that green. After green we light yellow and then red

It has a lot of wires connected but this is only because of programmer, it needs โ€œ+โ€, โ€œ-โ€œ and 4 more wires to communicate with the controller ๐Ÿค–

Making a model for the traffic light housing
This will be the tool to bring the housing to the life ๐Ÿ˜Ž

Weโ€™ve tried to build a piece of traffic light housing as well as some other things. Looks promising, but also needs to be ironed.

We have prepared drafts for the traffic light ๐Ÿšฆ
Next weโ€™ll use ironing to make them a bit more flat ๐Ÿคž
I expected it to be more accurate, but letโ€™s be happy with what we have โ˜บ๏ธ

Well, the ironing doesnโ€™t help much
But this is enough for the first DIY project! Right? Right?โ€ฆ ๐Ÿ™„
Weโ€™ve built a box and added more plastic. Now weโ€™ll try another round of ironing ๐Ÿšฌ

Okay, looks a bit better (but really a bit ๐Ÿค)
If you have an option to use 3D Printer or at least plastic sheetsโ€” use them without hesitation

For ironing I use this device, itโ€™s just a normal ๐Ÿšฌ with a flat soldering iron tip. I found 250C a good temperature for melting. Normally ~200C is the working temperature for PLA plastic.
