Hi,
I have a question regarding the DAQ project in
http://www.8051projects.net/downloads196.html.
In the included schematic, there are only four LM35. if i want to add 4 more LM35, i just need to connect them on pin 2,3,4,5 on the ADC0808 right?
For 8 relay connection, where do i need to connect the pin 5,6,7,8 from the ULN2803?
Do i need to change the c-code because i can only see setting for four relays in it ?

Thanx for your help.

Ajay

yes, you need to add on/off functionality for each new relay you are going to add.
Now, not only in the controller code, but you also need to check if the software support more relays, if not then you need to add few lines of code to support that too.
