Hello,
im making a simple mini project to turn on the lights by using barcode scanner,computer, usb to rs232 convert, transistors, relays, and bulb
im scanning a barcodes and im processing it through software in computer and generating a logic '1' or '0' depending on the barcode, and taking a output from computer as logic '0', or logic '1' and the corresponding transistor is turned on and the relay is driven and lights the bulb but whether this logic works with transistors i dont want to use uc if it works with transistors how do i need to connect please suggest something. Sorry if any thing wents wrong up there
logic '1' = turn on green bulb
logic '0' = turn on red bulb
here is the connection
thanks and regards
