I currently have a circuit with a 2N3904 BJT that acts as an on/off switch. I want to add a second BJT in parallel that toggles an LED on/off to indicate the on/off status of the first BJT.
I've tried simply connecting the bases of the two transistors together, but this has not worked, I think due to insufficient base current now that the current i is being split between 2 transistors.
If I halve the biasing resistor values to double the amount of current, but maintain the R1/R2 ratio, should this theoretically work?
Edit: Apologies for not adding a schematic, I wasn't aware there was a built in feature. This is the schematic I tried, which obviously did not work. Upon reading the comments, it seems that adding a resistor in series with the base of each transistor could help solve the biasing issue?
