Wordclock = WS2811B + Arduino = beautiful combination

wordclock_intro.jpg I wanted to make one a few years ago but I didn’t have much time as well as I didn’t know how to do it, or was too lazy to do it :D
Back then, I lacked of enthusiasm, motive and didn’t want to learn new things. Until this year, I had more free time and change of mind, I want to learn new things. So, I started this project, a few years after

ATTiny13 Programming with Arduino IDE

attiny13a-dip.jpg Sometime, you need a small circuit to flash some LEDs or do some simple task, say, power on delay function for your DIY amplifier, power on reminder for your soldering station (beep every 3 mins) - which I forgot to turn off all the time… probably, an Attiny13 is just what you need.

Arduino Analog clock with DS1307

arduino_my_name_analogclock.png Another experiment with Arduino based on experiment with TFT 240×320 display using driver chip ILI9341 and DS1307 real time clock module.

Turn out this can be a nice analog-clock on my desk to replace the widget analog-clock of windows 7.

240×320 2.8” TFT Display breakout using driver ILI9341

9341breakout1.jpg Playing around with 2.8” TFT display with driver ILI9341 from ebay. This one has SPI connection and SD card reader built-in at the back of this TFT display. I choose the display without touch-screen because I don’t need it for my next project.

But it seems I always have trouble with things from ebay: this TFT display using driver ILI9341 that accept 3v3 signal and the module doesn’t come with a level conversion chip like this LCD Shield using driver 4535.
