| May 4, 2018 at 21:53 | comment | added | sineverba | @Transistor thank you for your CL hints... but... on free cannot save or share :( Ok, I did understand the necessity of pullup... but, for my others question? Can you help me? | |

| May 4, 2018 at 21:42 | comment | added | Transistor | A couple of tips on schematic drawing: (1) With the CircuitLab tool you can save the editable schematic in your post. You don't need to take a screengrab. That way we can copy it into our answers and edit it. (2) Draw components with + at top. Your battery supply is upside down. (3) If you double-click on the Custom Component you can name the pins. (4) If the Arduino GPIO goes into tri-state (input mode) when going to sleep then you probably just need to add a pull-up resistor between Q1 base-emitter to keep it turned off. | |
