Hi Gerd,
 
Thanks for reply. So, do u mean that i need another power supply for the input signal for the h-bridge?  Then, Daq supply connect to the relay which control the power supply? Im quite confused, try to make things clear...
 
1 more thing about the Daq...im actually curious on can i actually use the DIO to direct send a signal to the h-bridge instead?
 
Regards.

Hi Gerd,
 
Which mean i can skip the implementation of the relays and stuff and focus on the TTL signal to my h-bridge?
Sry for all the electrical question. Im not good in it.

Hi Gerd,
 
My project is about controlling a car model with a PDA Bluetooth. For the car model part, i need to connect Daq(CF-6004) with H-bridge driver (L293D) to send the signal to run the DC motors (1st motor for Left/Right 2nd motor for Forward/Reverse). Controlling Part, remote controlling the car model with another PDA via Bluetooth. 
 
From the 1st post, I try to connect the Daq with H-bridge i made. But, last week i burned my H-bridge on the attempt and now i switched to use L293D instead. Hence, The specification of the signal might vary. For the L293D i used i need  2 supply for it, 5 V for the IC itself another 6 V for the DC motors. Supply from Daq 3.3V and 0.01 A.
 
About powersupplying circuit and sending signal i got no idea at all. I can't think of anything when i panic, especially i left 1 month for the deadline.
 
Please guide me.
