Bomba fake airsoft

Ola, alguem pode me ajudar com o codigo abaixo. (codigo de um jogo para airsoft)
Inicialmente o codigo pede apenas para inserir uma senha e sosinho coloca um tempo fixo predefinido para inicio do jogo. preciso colocar para digitar o tempo tambem. estou apanhando. (usando teclado 4x4 e lcd 16x2 e arduino uno)

Que jogo e esse ?
Estou desenvolviendo alvos para Airsoft para um cliente.

Caramba, Arnold, sua vida parece ser tão divertida quanto a minha… :heart_eyes:

O jogo consiste em tentar desarmar uma bomba relógio , com uma senha é um tempo de explosão determinado. (sirene). figura abaixo

ola estou com uma bomba assim ki montei mas estou com problema de alimentação de energia, uso bateria 9v mas nao dura mas que 1:30H, como vc alimenta a sua?

9v tem. Que ser Duracell ou panasonic , as marcas de recargavel são Porcaria.

Use 8 células de NiMh, são super baratas, simples de recarregar e aguentam alguns maus tratos
