The ring colors of a 100 ohm resistor should be brown-black-brown. Sorry if it’s missing from your kit. What you have soldered onto RLED right now is one of the two 1 ohm resistors. These two 1 ohm resistors are supposed to go to Rsc (but as explained in the instructions, one of them is optional). Please double check the Rsc resistors: if you have soldered both, I am pretty sure one of them is the 100 ohm you are looking for. If it’s not there, I am happy to send you one tomorrow.
