Im trying to get this 555 circuit working but nothing is happening. Ive been following a few different diagrams on the internet and none of them seem to work

I found this calculator on google. I entered 38.5KHz, 50% duty cycle and 0.001uF (1nF) capacitor. It said to use an 18.7K resistor for RB and 0K for RA. Ive been using a 15K resistor with a 5K variable resistor as another website said. It doesnt really matter if its at the right frequency for now though. the LED just wont light up at all (im using an LED for now so i can see it working).

Ive tried putting the output through a transistor. Ive tested the transistor by itself and it works fine.

My circuit currently looks like the one on that calculator site. Does anyone know what ive done wrong or what to check next?
