In the last experiment, we have found out the negating effect of the NAND circuit. Logically a negated NAND should again give a AND function. This is done in out circuit by adding another transistor in series to the output of the NAND gate. When both push buttons (switch 1 AND switch 2) are closed, the yellow LED turns ON.
