Useless Box

---- <b>Practical Project</b> ---- Info: A basic understanding of Arduino is necessary for coding and wiring. Another Practical Project, This one runs on an Arduino board with a rechargeable lithium-ion battery. It's designed 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) Additionally, you will need screws, wires, a soldering iron, and a glue gun. If you have an old power bank, you can use it for the step-up charger and lithium-ion cell. For connections, refer to the "Useless_Box.ino" or "Useless_Box_Relay.ino" code; it's quite simple. I tried to make it as compact as possible (10.5 x 7.5 x 4.8 cm). Optional: If you experience "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 don't hesitate to ask. NB. I did not write the code; I adapted it for my project. It was originally done by Vagelis Chantzis.
