Description
---- 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.
