Overview
Blinkenlights Stubnitz is an open-source printed circuit board by Peersen, from the Peersen/Blinkenlights repository on GitHub, published under the BSD-3-Clause licence. It is a 2-layer board of 100 × 75 mm with 34 parts on 32 nets, routed with 196 tracks and 0 vias.
It is built around the SN75176AD. Its parts include 15 connectors, 10 resistors, 2 capacitors, 1 IC and 1 switch. It belongs with the AVR (ATmega, ATtiny) boards of this library.
Main components
1README
README.mdBlinkenlights
An Arduino Nano sending DMX to a Driver Chip making several Dimmerchannels blink in a random but controlled manner. It uses four potentiometers controlling:
- overall Level
- speed of the fading lights
- range how far the lights fade out from Base LEvel
- the amount of lights doing crazy stuff
PCB
- one sided for home-etching
- Dip switch for dmx address
- selector jumper to switch between sending and receiving dmx
- spare poti connectors for later use
- I2C Pins
- reset Pins
- Screw terminals for Vin and 5v rail of the arduino and DMX signal from the SN75176 tranceiverchip
Other projects in this repository help to troubleshoot the main project
- a dmx receiver making six Leds blink
- a softwareSerial receiving arduino that sends received strings to the arduinos USB COM port
To Start
- if you use Platform IO: make sure to change " lib_extra_dirs = D:\ArduinoSketches\libraries" in PlatformIO.ini
- install DMXserial Librarie by Matthias Hertel: http://www.mathertel.de/Arduino/DMXSerial.aspx or https://github.com/mathertel/DmxSerial
