Arduino nano : stepper motor + laser + sensor + endstops + batery

A cada pulso dado em uma porta de entrada, o sera dado alguns passos (regulaveis) no motor nema, ate detectar alguma alteracao no sinal do feixe do laser ao sensor foto voltaico.
As endstops sao pra delimitar os limites,  Todas as informacoes devem aparecer no visor lcd (Oled 0.96 I2c ). A bateria devera ser usada apenas para manter o lcd ligado enquanto o conjunto nao estiver ligado nos 12v.


Qdo ligado a uma fonte 12v, a bateria devera ser carregada, com seu stats aparecendo no lcd. Cada operacao devera ser iniciada por uma porta digital e  com uma porta de saida, dar o feedback.

As which pulse is given on an entry, some steps (adjustable) will be taken on NEMA steppermotor until detect any alteration on light beam sign of photo voltaic sensor.
Endstops are to delimit the boundaries. Every information must be seen on LCD visor (Oled 0.96 I2c).


The battery will be only used to keep LCD visor switched on as the whole system isn’t switched on 12v. When it is, battery must be charged, and the status can be seeing on screen.
Every operation must be started by a digital door and an output door feedbacking the actions.
