Pedestrian Traffic Light - Ampel (fuer Fussgaenger)

Description

Pedestrian Traffic Light 

Quick and easy to build - Snap fit - no screws needed

Final dimension assembled: 4x4x15cm (LxWxH)

Print

• No support
• Orientation as in the files
• Infill 15%  
• Material: PLA 

Parts needed 

• 1x WS2812 / Neopixel stick (or similar e.g.  https://www.roboter-bausatz.de/p/8bit-rgb-led-leiste-aehnl.-neopixel
• Jumper cable ≥ 20cm e.g. https://www.roboter-bausatz.de/p/40-pin-dupont-jumper-kabel-buchse-stecker-40-cm
• Microcontroller (Raspberry, ESP32, Arduino ,  Calliope,…)

Cut

Cut 2 pixel from the stick to make it fit into the housing. (see pictures)

Solder

Cut the jumper cable on one side and solder it to the LED stick (GND, 5V, DIN)

Assemble

• Insert the stick 
• Fix the stick by using the spacer 
• Push the cable including connector through the standpipe
• Connect the stand pipe

Connect & Code

Pls. note that the WS2812 (Neopixel) stick is directly connected to the controller. It does NOT need a own power source. Connect just the controller.

This is possible by using only a few LEDs. The controller can deliver enough current. Voltage 3.3V or 5V does not matter in this case.

Calliope: 

LED Stick 5V → Calliope +

LED Stick GND → Calliope - 

LED Stick DIN → Calliope P0

Code example:  to follow

ESP32: 

LED Stick 5V → ESP32  3.3V

LED Stick GND → ESP32 GND

LED Stick DIN → ESP32 D16

Code example:  to follow

Arduino: 

LED Stick 5V → Arduino 5V

LED Stick GND → Arduino GND

LED Stick DIN → Arduino D6

Code example:  to follow
