Arduino library for using matrix keypads

Password based circuit breaker is a technology where we can control any circuit by a password. If we enter a password the circuit gives a break that means it is on. It can mainly be used in case of electric lines. Nowadays, electrical accidents to the line man are increasing, while repairing the electrical lines due to the lack of communication …
