Need to build circuit interfacing with COM
Posted on 2005-03-13
I want to build a hardware/software project which will monitor the download speed of my
dialup connection. This will be a device with 6 LEDs. I have already written the software
which gauges the speed and enumerates it. Now I need to build the circuit so that this
circuit recieves the number (0-6) via COM port and lights up that many LEDs. For instance
if my application detects that the current download speed is 3.22 kbps, it will send 3 to
this circuit, which should in turn light up the first 3 LEDs to indicate that the current
download speed is around 3kbps.
I have a very basic knowledge of digital circuits. Will I need to buy one, I guess this one
will be pretty easy to do it at home with help of some ICs or something. Please do guide me
on how to proceed.
p.s. I couldnt find which category to put this question into, so I asked it here.
