Made: JLCPCB TinyDev TM1637 modular LED matrix clock with ATtiny85

Описание: This video is sponsored by JLCPCB. Go to https://jlcpcb.com to order your PCB's for only 2 USD plus shipment.

In this video I will show you how I made a small modular LED matrix clock for Arduino. It consists of the following parts:
a mini breadboard
the TinyDev development module, featuring an ATtiny85
the TM1637 6x5 LED matrix module
the 3x1 pushbutton extension module
the prototyped ISP-USB power module
a DS3231 realtime clock module

The video shows how I used EasyEDA to design my modules and how I used JLCPCB to manufacture the PCB's. I show you how I solder and test each module before assembling the clock. Next to that you can see my ATtiny44A development module and the modified TM1637 LED display (both shown in previous videos).
