Arduino based clock using 16x32 RGB LED matrix

thingiverse

Arduino based clock with illumination, temperature and humidity sensors using 16x32 RGB LED panel In clock.zip file there are all files needed to reproduce this clock. Eagle schematic and PCB layout files, sketches and case drawing. In file seeedstudio_gerber_files.zip you can find Gerber files for seeedstudio Fusion PCB service. You can order PCB by uploading this zip file here Total cost will be something like 120$ I will add more explanations on request if someone interested to reproduce this. How I Designed This LED panel arrived. First test First prototype Completed Instructions Parts list You will need flowing parts:16x32 RGB LED matrix panel - 25$ Generally any 16x32 RGB LED matrix using HUB75 interface and 1:8 scan rate should be okSparkFun Humidity and Temperature Sensor Breakout - HTU21D - 15$SparkFun Level Translator Breakout - PCA9306 - 7$DS1307 - $4.74CRYSTAL, 32.768KHZ, 12.5PF - 1$ATmega328 with Arduino Optiboot (Uno)x2 - 11$CRYSTAL, 16MHZ x2 - 0.7$E-SWITCHx2 - 0.2$MCP1700 - 0.3$RUEF250U FUSE (optional) - 0.35$Socket, DIP Socket, 28 x2 (optional) - 1.3$BATTERY CONTACTFOR 12MM CELL - 0.5$Ceramic Capacitor, 22 pF x4 Molex connector 4pin x2 Molex connector 2pinCeramic Capacitor 1 µF LED 5mm x2 Ceramic Capacitor 0.1 µF x10 Resistor 10k x6 Resistor 4.7k x2 Resistor 330 x5 Resistor 1k x2 Electrolytic Capacitor 100 µF x2 DC Barrel Power Jack/Connector Hopefully I didn't forget anything If you are not interested in temperature and humidity sensor you can save near 22$ by not buying HTU21D and PCA9306
