you know cool....and lol, i dont think you looked who wrote the message...shima...i have been discussing about the ba...for a week with you...ha ha ha ha!,
but i was thinking of a bridge like that because i have a lot of trasnsitors "begging" me to use them. lol, but about the expansion. i need to use the transmitter/receiver i have. normally you can send 16 codes to it, but i was thinking of expanding it to 8 bits, because if i were to decode it i would have 16 outputs, but ONLY ONE high at one moment. so not enough. could be something like sending 4 and 4 bits and to put them together and form 8 bits, but ill give this a thought, anyway, send me some other suggestions.
