Also check that your ground connection to the Raduino is correct.
If your GND to the Raduino is OK, but you're still getting only 0.04V out
of the regulator, then
- either the regulator output is somehow shorted. Inspect the Raduino
board, check for any shorts, check capacitor C3 (1 uF).
- or the regulator is defective (replace it)
