I use a combination of Arduino Nano and ESP-01 for many projects. I want to reset both processors using the reset button from the Nano. The Nano works with 5V, the ESP-01 with 3.3V. How can I connect the two reset pins? (The ESP-01 must of course not be damaged!)

Reset ESP-01 with Nano Reset Pin

The reset line appears on the ICSP pin 3, so you can pick it up there. Use a Schottky diode, e.g. BAT46 or 1N5711 if you can find one.
