While waiting for more people to join. Let's keep ourselves busy with this little exercise.
What's Digital? Think about a light switch. It's either on (the light is shining) or off (the light is not shining). There's no in-between. This is similar to how digital works. It's like using a simple switch to control something – it's either a 0 or a 1, like flipping the light switch on or off.

What's Analog? When you turn the handle of a water faucet just a little, a small amount of water comes out. When you turn it more, more water flows. It's like a smooth, continuous change. In electronics, analog is like this – it's a way of working with signals that change smoothly, like turning the faucet handle to control the water flow.
We must understand these basic concept.
Do you know one thing, I never read and study while in school as I did in self developing myself. Even as a master holder in Control Engineering, I still study more than those writing their final year exam.
This class will be interactive in nature. Do your research and tell us what you know about Digital and Analog.

ytdivine:


Very good answer. Am very excited. It shows somebody is ready to learn and my input is not in vain.

However, I need more response. I don't want anybody to be left out. We are gradually entering the main thing. Very soon, we will write our first Ladder Logic Program. If you don't understand this concept you will not move an inch with us

Southboy:
I want to suggest that you create like a Telegram group and drop the link here for everyone that is interested to join. Then people will know when a new message is dropped and they can respond to it on time.

ytdivine:
Now, we are talking about electronics, it does not know yes or no, big or small etc, these two conditions are only relevant to us. How do we now present these values electronically?
Please answer the question!
Here we are now talking about signals present or not. Is either there is signal or not. No two ways about it.
What do we mean by signal? This is another question.
Well, I don't want to start explaining what's called VOLTAGE and CURRENT. I assumed you know this, if otherwise alert me.
The common digital signal we use in automation is
24vdc (direct current voltage)
Another common one 5vdc
Here we are going to be making use of only 24vdc

Coming down to digital meaning
24v present
Or 24v not present.
We are going to represent these two conditions with a symbol which will be used in the PLC programming.

I hope I have not confuse anybody
If you understood the whole thing up to this point, please indicate

What do we mean by signal? This is another question. - A signal is like a message that one part of a system sends to another to trigger a specific action or response. Just like how you might use hand signals to guide traffic or communicate with someone from a distance, signals in automation help various components "talk" to each other without direct human intervention.

Newusername:

Why should we create a telegram link when we have this platform. Is it really necessary?

Southboy:
I would like to express my gratitude for dedicating your time to educate us on the subject of automation. If you're willing, could you kindly provide us with the following information:

1. What is the primary goal of this training?
2. What topics and subjects will be covered in the training curriculum?
3. What level of understanding or knowledge do you anticipate participants will have by the conclusion of the training?
4. Are practical hands-on sessions included in the training program?
5. Is the training only for Engineering students?

Essentially, could you outline the overall structure and organization of the training? Your insights would be greatly appreciated.

Southboy:
We are asked to answer a question but because people that showed interest in the training are not notified that there is a new message, or they forgot about the training. Either way it slows down the class. It's just a suggestion though

ytdivine:
In automation we talk about
1. Digital signal
A. Digital input
B. Digital output

2. Analog signal
A. Analog input
B. Analog output

First assignment with #200 recharge card.
We use 24vdc to represent digital signal. What do we use to represent analog signal?

Southboy:
Analog signals can take on any value within a specified range. For example, in an industrial setting, an analog signal representing temperature might use a range of 0V to 10V to represent a temperature range of, let's say, 0°C to 100°C.

Another follow up question

What is Transducer?

Southboy:
I don't have an Engineering background, would you still advice that I continue with the training?

ytdivine:
I will continue the moment my questions are answered.

ytdivine:


Your effort is so much appreciated. Do you have a phone? If yes, how come you are successfully making use of it without engineering background?
It's just interest and determination, by the grace of God, I can even train a goat much more an intelligent fellow like you.
Feel free to make attempt always and ask questions.
Engineering knowledge started one day

ytdivine:


You tried. I give you 25%

Another follow up question

What is Transducer?

Southboy:
Please provide the correct answer

Kingslaw:
A transducer is an electronic device that converts energy from one form to another. Common examples include microphones, loudspeakers.
