I was working on a circuit and didn't understand how to connect what/where in the op amp.
Could someone help me in reading and understanding the diagram?
The schematic looks quite clear, so what exactly are your doubts?
I'm using it to get serial out of my android phone's audio port and input it to my roboduino.
It's not that the schematic is not clear, it's just that I'm not good at reading circuit diagrams and I have no idea how to connect each wire to which pin on the op-amp and that kind of stuff. For example the lm324ad op amp on the top (U1A) is recieving voltage from VCC, now i have no idea which pin on the op-amp should i connect the VCC wire to and so on.....So i would appreciate it if u could help me with the pins on the op amp and how to understand which pins to connect what to....
The pin numbers are on the schematic you posted (small blue numbers), so I still don't get what you need further.
QuoteThe pin numbers are on the schematic you posted (small blue numbers), so I still don't get what you need further.Well I didn't know they were the pin outs!Anyway....thanks soeren and billhowl...got it now. @soeren: out of curiosity....in what way is the lm393better? I mean using the lm324 some guy has reached 24000bps. I think 9600bps is fast enough for my current needs.
Here are the links:
[...] you will get a nice TTL signal from this. If you invert it, you can talk to a RS232 serial port directly.
I think it is a reliable circuit....quite a few have rated 5 stars in the market and more than a 1000 downloads.
I really cant comment on how professional it is....u might be able to help though..btw i'll try it with the lm393 also and see if it makes any difference at all with my roboduino.
