I am in india.

You'll also need to invest in a pair of good quality safety sandals.

 

Your will to learn is commendable. Don't give up. Just try and visualize what your goals are, and stay on course. We're here to help.

 

Tomorrow is Sunday. Sounding auspicious. Let's start at 2 PM Indian Standard Time.

That soldering iron.

 

I would start with something more simple.

 

A simple led flasher would be a good start. Just an idea.

 

I still believe I can do it. Not overconfident but self confidence.

 

Shall I proceed on the below said method?

 

First step is to remove the protuding pins? And then solder?

 

You could solder the wires directly on the pins. But first you'd have to tin the pins, tin the tips of the wires, and then solder then together

What solder wire diameter and type will you be using?
Do you have flux available? I'd suggest paste-type flux for this application.

 

Removing pins is another level above soldering, there is risk of damage to the board if not done right. There are options to order micro boards without the pins attached, next time keep that in mind...
At this point, it may be best to simply tack solder the wires onto the top of the pins, being careful not to short anything.

It looks like the ESP32 already has male header pins. I'd solder male header pins to the display and use female-female DuPont jumper wires.

I breadboarded/prototyped a scrolling LED clock around 10 years ago and stopped working on it. I replaced the white jumper wires with some DuPont connectors:

 

I agree with dl. Don’t remove the pins. Use female-to-female jumpers.
This gives you the flexibility of changing the connections without having to solder.

 

First step is to remove the protuding pins? And then solder?

I'd say the first step is more practice, you must get used to how solder behaves, how it behaves with your particular soldering iron. So start by soldering bits of wire together, get to recognize the different states the solder gets into.

Make sure the metal is always cleaned from dust or even fine grease and oils like we have on our hands.

Heat the thing not the solder, heat the two wires then apply solder to them with the iron still there.

Unless you practice then every actual solder joint will come out like your first joint.

There are many ways to solder two wires together, depends on whether the wires are strands or single wires and so on.

If you can solder two wire ends together to a high standard the you need to practice until you can.

 

Hello,

The attached pdf will give you tips on soldering.

It seems like the problem is more than just eyesight. There's mostly too much or too little solder and it's not being applied in the right place. Possibly, the tip isn't being positioned correctly; or it's the wrong size/style.

Get yourself some magnifiers. I use these for precision work:

Or these clip-ons for my glasses:

I also have several of these:

And one of these (without the iron holder):

I have an illuminated magnifier, but I'm used to soldering by seeing the board directly, so it will take time to adjust to doing it via a magnifier.

 

I read, write, blog, eat, work all by sitting on the floor only. A work table would be convenient but has to be bigger in size otherwise floor would be always much convenient.

I wouldn't describe a table or bench as a convenience Shafty. These are the kinds of things that make some activities extremely challenging, you waste time and energy without them, everything you do becomes more time consuming, more likely to come out wrong or bad.

I've soldered stuff on floors, I'm sure many of us have, but for delicate electronic work it's a bad idea, you are setting yourself up to fail.

I think this is why you've had little practice, soldering anything is difficult on a floor, so you've probably formed a view that soldering is a big challenge, something that's a huge obstacle to overcome.

Seated at a table, sitting on a chair with a decent lighting, is part of your problem, trust me on this, I was poor once, living in Liverpool in England with no father in the 60s and had nothing but an old unused terracotta tiled corner of an old kitchen, so I made a workbench from scrap wood, spent days on it and made it strong and solid and then painted it. It cost me zero except for perhaps a few bolts/screws.

Once I did that I was able to do so much more and a lot more quickly.

So forget soldering, forget electronics, you need to focus on getting/making a strong smooth surfaced worktop, fix that and everything else will fix itself, you'll be soldering like a professional a few months.

 

Next step for you is get off here and go put some of what you have been told into practice, post some pics of your efforts so we can see.

Decided to sleep only after finishing this project. And the time here 3:33 AM

 

Computing on a laptop and doing soldering while you and everything else are on the floor is very bad body posture. You may be young now while your body can take a lot of abuse. But you will suffer for this later on in life.

At the very least, get a carton and use that as a table top.
Get two cartons or wooden crates of the same height and place a plank on top. Space the boxes so that you can sit on the floor with you legs under the board.
