After a while, I have come to fall in love with embedded systems.
Some of us may ask what is embedded system?
Simply put, embedded systems are mostly control systems involving micro controllers.
Examples of embedded systems
Wireless control systems for electrical devices
Gps tracking systems
RF demobilisers.
You can add to d list. Especially d ones you have personally worked on.

Let's us all come out on dis thread to discuss embedded systems.

I personally has worked on wireless control system from d internet.
My device when installed in a particular location, one can access it from d internet and then use it to turn off electrical equipment like fans, tv, ac's etc.
I used PIC16f887 and wrote my codes in C using basically codes from mikro C library.
And used RF module for wireless serial communication between my micro controller and the control PC.
I used hyper terminal to access serial port but I ll use VB application when I deploy the system for public use.

Hope not wot am thinking. Does it mean there are no computer engineers in nairaland. Or I posted d topic under d wrong forum

I tot we ve computer engineers in nairaland.

Am not sure if dis is d right forum for ma topic........

I am intersted, i like hacks, but can u get all this components in nija? When i was in skull people use to code 8051 chips to desplay signs on led dashboar, it was machine code, good if want to understan how controllers work at d lowest level

Its not just machine code. C can be used as well. I would ve loved to discuss with ppl who ve done one project or another in embedded systems.

@Dondbuzor

Sure, we have engineers here on nairaland, but most of us aren't really practising anymore.

Embedded systems is a hobbiyist thing I do now...once in a blue moon though. Done some uControllers based projects (personal). The first was rebuilding my final year project (an electronic home controller based on the Intel 8085...awesome chip set) with a PIC. With the PIC, I added internet access to it, thus I could access basic features (turn lights on/off, check if NEPA never carry light! ). Pretty cool!

@Donbuzor sure u can use c, but u still have to use a compiler for it, i think if u know the instruction set u will be able to right more efficient programs, i will start playing this things just dat i hardly have d time anymore

@maleeq why do u chose to do embedded systems as a hobby. Does it mean u can't see the large market available for embedded systems in naija. Y am saying is because most of computer gurus I know are all into programming, web development, app development etc. But hardly do u meet anyone into embedded systems.

@ostadimma how I do my thing is that I first chose a particular compiler that has enough library for a a particular ucontroller. With that, I free my self of studying the architecture and instruction set of that particular micro controller. So with the lib function in a compiler, I can know wot a particular micro controller is capable of.

@Dondbuzor dats dat is true, but are u fully into these projects, or part time? Is there a thriving market for this kind of projects in nija? Where i stay they have this motor dat pumps water into a tank, the wahala is dat u have to switch it on manually when ever there is light, and of when it feels up, a controller can automate this chore

All u need to do dis project is a sensor that can measure water level and a micro controller. Its very simple and straight forward.

Thinking about it i dont even need a controller, sensors are like switches, low voltage ofcourse, i can switch d motor on/off by connecting the sensor to d motor power via a relay

@ositadimma
If I give u d complete circuit diagram and circuit components, d C program for d controller, can u build it urself?
Kk I les I forgot, u might face challenge in burning d hex file into d micro controller. But if u can see who can do that one for u, then u can get d rest of d components as I ll show u and connect it together then u are good to go!

@ositadimma ve u found d sensor u re going to use for dis project. So how do u implement ur system to always pump water once the water level is low and there Is power supply

Guy it was an hypotesis ooo, my interest now is in d raspberry pi, i want this thing but the dont ship to nigeria.

Wots rapsberry pi?

Like the majority, I deviated into full time programming. I've still got the flare for embedded systems but not the time to really pursue it (guess i am a bit lazy).

@maleeq this is wot am thinking, since most IT gurus are into programming; this simply means that d man power in embedded systems is not enough for d teeming population in naija.
I simply mean that there is less competition in embedded system and thereby making it more profitable.
Wot do u think, embedded systems and programming, which one is more profitable?

I am nt a programer nor an engineer bt I m a scientist! and Im interestd in the PIC for a project Im conceivng currently. Im particulaly happy u have implemented sometng wit PIC and I wuld like to have the details of how u source all ur materials in Niaja (I mean all, PIC module, PIC Programmer, the compiler and the sensors). Im woking on sometng that culd sense atmospheric parameters(temperature, pressure, etc) display and store it for onward transfer into a laptop for further analysis!

U first have to know and understand d circuit components u need, the sensor type u ll need to measure temp and press. The type of micro controller. Even though u might want PIC, u ll still have to decide the type of PIC u ll need (there are over 50 types of pic). I personally I always choose PIC16f887 bc I ve d materials, examples and compiler for the pic.
And since u ll be using a PIC, u ll also need MikroeC compiler(google it).
And u also want ur device to send information(communicate) with a pc (whether wired or wireless), ur project will also involve serial port communication.
NB all the components u need are available in naija. It depends on where u stay.

I ve done similar project beforen goodluck to u.

@corgitoErgo u can aslo check out dis thread

on programming section to see how provided a detailed analysis on how I constructed one of my design.

Pls I need an answer. Embedded systems and programming which one has more opportunities(profitability) in nigeria.
With reasons plz

Dondbuzor: Pls I need an answer. Embedded systems and programming which one has more opportunities(profitability) in nigeria.

In Nigeria, I would say there is more market for programming than embedded systems.

Wots ur reason. Is it becos everyone is into programming?

thanks frend, I had discused somethng like this wit some people here on NL b4, bt d fear fear of sendng mony to some unknown persons and they did not realy said they used PIC!
Im actualy n Jos, but I do ocasionaly come to Ilorin.
culd u posbly help in getng some of materials?

The trick is this; meet those road side electronics repairers, ask them where they buy their components. From there, u can get more information on where to get d rest of the components.
Just give it a try!

ur suggestion may work fo transistors, OpAmps, TTLs etc but for microcontrollers and their programmers, I doubt it? But its still a good advice, I will try it!

Give it a try. U ll come and thank me later. If they don't sell the PIC, they will tell u where to buy them.
