PiG 1 - Soldering Iron Step

so what ? You started the GoloHttpServer, showed something on Raspberry and… nothing ?
Yeah, I know. But c’mon, I still need some sleep and still don’t have 72h days ;)

Last week end, I started the next step in the Little Hardware meets Little Software. yep, I bring back on the desk my soldering iron!

I had to prepare several items:

• a kit to assemble cobbler breakout to use on my breadboards
• a 2 lines LCD screen

So everything is in place.

Let’s start by puting the header pins in the cobbler PCB.

To have something stable, you can use a small breadboard and slot the header pin in it.

I didn’t work with a soldering iron for several years… not too bad :)

Don’t forget the ribbon cable socket:

At that point, the cobbler breakout is ready.
Now it’s time to put some wires on the HD44780.

The wire stripper is my best friend when there’s a lot of wire to prepare:

A third hand tool is very helpful to solder the wire to the LCD panel.

You have to wire pin 1 to 6, then 11 to 16:

The LCD has now wires. It could be better and I wonder if I won’t try to solder head pins on another LCD:

Here we go!

At the end, I have now everything to start to work with my Pi!
The next step has already started and I’m running basic piece of code to test the cobbler, the Gpio…
The Gpio and its wonderful pin numbering, guided by a logic that only an advanced Scala user may understand ;)

See you soon, with pieces of Golo lang to interact with a small red led on a board :)
