Hi! Is it possible to do the opposite? I need to generate a negative pulse from Arduino to control a latch solenoid valve. Positive pulse: open, negative pulse: close. Thanks
Hi. Is it possible just to meassure the voltage of a 18650 battery using any of the analog pins? Do I still need a voltage divier? Since Arduino can measure up to 5V I don't think it is necessary, but just want to make sure. Thanks!

So when the battery is charged, the TP4056 won't charge it anymore?
Hi! Congrats on your project. I'm working on something very similar but instead of a router, I want to power up my Raspberry Pi. What I've done is what you can see in the images attached. I'm using a P-Channel MOSFET to switch from mains to bat. Currently it is not working because of the transistor (I need to find the appropriate part #).Reading your project description I noticed you do not use that kind of switching, you're powering the DC boost module from TP4056 directly. Would't that affect the way the battery is charged? I'm asking this because the module will be charging the battery while powering the Raspberry (or router in your case).Thanks!
Hi! Can you share the schematics for the project? (wiring between components, ESP and Arduino). Thanks!!
