i have realized an IR transmitter and receiver circuit using 555c, bc547, tsop1738, n required resistors and capacitors. I am getting the required output but the problem now is that, the output obtained from the collector of BC547 is negative DC supply. is there any possible way so that i could obtain positive switching instead negative supply?? |

Can you make your circuit public or unlisted so that we can see what you're trying to do. No circuit: no help! :) |
