Looking for someone that design for me a simple device

[mrdebug]

I need a device card with:
a ftdi multiserial chip (usb, virtual com port).
In one channer I need a 125 reader
In another channel a rgb led + 2 relais.

Do you have a schematic?
And do you want a PCB layout?

No, I haven't got schematic and I want the pcb layout. Are you able to draw it?

[Laurens-wuyts]

I'm not sure how you would like to have it all connected and which parts you would like to use.
Can you please post some links to the parts etc. ?

I need an usb interface to use with a pc or a raspberry pi with a rfid reader (125) and a relay, a buzzer, a rgb led. I'm thinking about the 4 channel ftdi chip. One channerl for the rfid reader, the second channel for the buzzer, relay and rbg led.
Are you able to draw it?

[Laurens-wuyts]

You'll also need a microcontroller to control the relay, RGB and buzzer.
When you use 1 microcontroller for these 3 things, you only need a 2 channel FTDI chip.

If I'm wrong in this please let me know. I'll start with making schematics so you can say if i's correct or not.

I've been thinking, why don't you use an arduino mega?
It has 4 Uart connections (-1 if using USB).

Can you explain better? I haven't got experience with hardware. I'm a developer.
Can you suggest me exactry what is needed?

[Laurens-wuyts]

You'll need an arduino mega, i have this one.
The arduino mega has 4 UART ports UART0 - UART3. UART0 is used by the USB connection.
When you connect an arduino to your computer it's automatically a com port.
The arduino can also control a relay, an RGB Led, an RFID reader and a buzzer.

Ok that seems gretOk that seems great but I need not only one device but more than one. Are you available to design it for me? I will pay. if you send me an email at info@denisgottardello.it or skype mrdebug I will explain better.
