Greetings sir,
"how come i didn't get a response"
Perhaps your first post is too general.
You ask about Infra Red emitters, receivers, encoders, decoders, micro controllers,
programming, fan motor speed control, 555 timers, EPROMs, EEPROMs (flash) and parts purchasing.
This is a bit overwhelming.
If someone provides answers to all of these who should get the diploma?
I recommend PIC micro controllers from
www.microchip.com
Microchip's web site has a wealth of information on using these controllers.
You will be able to purchase these chips from
www.digikey.com
They are relatively inexpensive. I am not familiar with shipping to Trinidad.
There is a forum at this site specifically for PIC/BASIC programming.
You also might want to make separate inquires about IR and fan motor speed control.
Best wishes on your endeavors.
