This project is rework Schematics and PCB 3D Wire Bending Machine from [howtomechatronics](https://howtomechatronics.com/projects/arduino-3d-wire-bending-machine/), where it is described how to work with the board and how to program it, including the source code for arduino.
***Because this board can be used for any different control of three stepper motors with Arduino, it will certainly find us...
This module makes it possible to switch entirely off the 3D printer using a WEMO (or similar) switch. If you need the USB power for flashing the 3D control board, you can use the switch to power the control board.
Pequeno projeto de um carregador de bateria eletrônico automotivo profissional.
> Descrição geral
O projeto determinarar o carregamento chaveado por um CI LM 358, com sistema bootstrap, com LED indicando EM PLENA CARGA(carregamento) e LED FLUTUANTE (Carregamento concluido). O sistema também conterar uma chave de liga e desliga orientado por sistema de curto e circuito (fusivel).
