The receiver's output is high and goes low when there is a signal.
The low output then triggers the Base of the (PNP) transistor which in turn lights the LED.
Now everything seems to be working,but when there is no signal the receiver's output is random and the LED just seems to flash or stay on randomly?
Can anyone see what is wrong?
Also the datasheet for the 7805 says to use a 0.33uF (Cl) and 0.1uF (C0) is this correct on the schematic as i don't really understand what Cl and CO stand for!
I am aware that the schematic is poor, and i am very ashamed of myself
