Hand tools and fabrication machines
I have found a lot of examples, which with a LED matrix so everything can be displayed (also on Hackster.io) and so I ordered myself an LED. But what a surprise: in the electrostatic bag were only the 9 parts.
I'll show you my step-by-step procedure, so that you can finally make "Blinky-Blinky".
...with a soldering-station and a side cutter.
Put the 10K resistor on the PCB and short the long legs on the other side:
Put the 0,1uF condensator in position C1:
Put the 10uF condensator in position C2 - you will find + and - symbols on the Board: the longer leg is +.
Solder 2x 8 lines on top and bottom in order to be able to press the matrix into the preparation:
Solder left and right 2x 5 lines.
Solder the preparation for the MAX72xx chip - you will find a small notch on the chip itself, as well as on the preparation and the board itself, which indicates the direction upwards.
Press the LED matrix with the 2x 8 legs in the preparation. That's it.
The LED Matrix is chainable therefore you will find 2 preparations for data in, CS and Clock on the left and right side. In the Arduino IDE install the necessary library and check your work!
Use an example-sketch from the libary and flash on your device.
Update 04.09.2017: I attached an example code which shows the Alphabet inclusive numbers and german Umlauts - get ready for "Blinky-Blinky".
