Assume I know nothing and need lots of help !

WoW, you guys are the best !!

So, am looking at getting 8051 Microcontroller, and 2 ADC0808, banging them together. a bit of code and hey presto data logger !!!

I have looked up commercial versions that do the same basic job and the can cost anything from 2000.00 GBP !!! Scarey

I have found a dev board for the 8051 for 22GBP https://uk.farnell.com/1291450/semiconductors/product.us0?sku=SILICON-LABORATORIES-C8051F005-TB

And the ADC 0808 for 5.48GBP
https://uk.farnell.com/9486674/semiconductors/product.us0?sku=NATIONAL-SEMICONDUCTOR-ADC0808CCN

So with the little extras I will need am looking at the sub 100GBP mark, fantastic !

So I'll get those on order with a few bits of stripboard and report back

That is unless you guys come up with any other ideas !

P.S. can't thank you guys enough for putting up with me..

Unless you're in India, I would forget the antique 8051, and separate ADC's - use a PIC with an in-built ADC and a couple of CMOS switches to select your 16 channels (do they make a 16 to 1 CMOS switches?).

Or, instead of CMOS switches, you could use two PIC's with 8 ADC inputs each to give your 16 channels, connect them together using a pin as a serial connection, and have the master one provide a serial connection to the PC.

You'll find absolutely lots of information on PIC's, and it's a far better solution than 8051's.

Well, suppose am close to India, Warwickshire !

But am going to go down the 8051 route, as in my limited knowledge it seems easier to begin with, and time frames are tight for me..

So on that vein, I have ordered

(8051 proto board)

and 2

(ADC0808)
https://uk.farnell.com/9486674/semiconductors/product.us0?sku=NATIONAL-SEMICONDUCTOR-ADC0808CCN

one

(rs232 Line Driver) (and yes, is a stab in the dark so am ready to be flamed )
https://uk.farnell.com/9664530/semiconductors/product.us0?sku=ON-SEMICONDUCTOR-MC1488PG

I'm using farnell (https://uk.farnell.com/) as a friend has an account with them)

A few bits of strip board, and an assortment of other goodies...

So once the ritual "you bought the wrong stuff" has been said, any chance I could be cheeky and ask you to point me at the right stuff lol ...

If you feel am asking too much, I appologise in advance, but I sort of backed myself into a corner


TIA
