---- Useless Box ----

info: Some knowledge of Arduino is required for programming and wiring.

Another Useless Box, This one is running Arduino with a Li-ion rechargeable battery.
It is ment to fit the items listed below.

2 x Tower Pro SG90 9g Micro Servo.
1 x 5V Step-Up Power Module Lithium Battery Charger.
1 x D1 Mini NodeMcu.
1 x Li-ion Battery 18650.
2 x Switches.
1 x Led (optional)
Besides that you will need some screws and wires, soldering iron and a gluegun.

I you have an old Powerbank, you can use it for the Step-up/charger and Li-ion cell.

For connections look at the "Useless_Box.ino" or "Useless_Box_Relay.ino" code
it is pretty simple.

i tried to make it as small as possible (10.5 x 7.5 x 4.8 cm)

Optional:
If you have "Servo twitch" the easiest fix is to run the Servo power through a "relay" See BC547_relay_arduino.jpg
and use the "Useless_Box_Relay.ino" code.

If you have any questions, please feel free to ask.

NB. I did not write the code, I adjusted it to my project.
It was done by Vagelis Chantzis. https://www.instructables.com/id/Arduino-Useless-Box/
