LRTimelapse Pro-Timer Free for newbee - help wanted -

Bonjour tout le monde Salut Gunther
J'essaye de construire le Pro-Timer (https://lrtimelapse.com/lrtimelapse-pro-timer-free)
mais mes connaissances sont très basiques dans le domaine
J'ai reçu tous les composant et chargé le programme dans la carte Arduino
Par contre pour faire les soudure je suis un peu embêter car le dos du LCD Sainsmart est different de celui de la photo voir photo ci dessous
qqu'un peut il me dire ou faire les soudures correspondant a cette image (fil rouge et fil noir)

Je crois que pour le reste j'ai a peu prêt compris ...


Hello everybody  Hello Gunther
I'm trying to make the Pro-Timer (https://lrtimelapse.com/lrtimelapse-pro-timer-free)

But my knowledge is very basic, I ordered and received the components and loaded the program into the Arduino card

But I have a problem with the LCD Sainsmart,  the back of the LCD  is different from that of the photo see photo below

Can anyone tell me or make the welds corresponding to that image (red wire and black wire)

Based on this circuit diagram it should be the pin that goes into the "digital 12" hole on your Arduino Uno. It's the Arduino that's doing the computing, so this doesn't rely at all on the LCD, but if Sainsmart have done any pin-alterations between their models (which I doubt), you might face problems with getting the LCD to work (without similarily altering the code). As said though: most likely you will just have to use pin 12 Smile

The reason Günther, in his guide, tells you to solder on the LCD "shield" is because it's got more easily available soldering points. As I'm sure you've noticed most parts of the Arduino are "hidden" below the shield, meaning it will be easier to have loose wires connected to the shield (the current doesn't care if you've soldered to the shield or the Arduino, as long as it goes into the correct pin).

Edit:
I re-read you post, and I see you're asking where to place the red and the black cable. Generally black is used for ground (meaning any of the holes on the Arduino marked GND), and red for the digital pin you're using (in this case pin 12)
