Muitas vezes, ao programar com o Arduino, acontece que é preciso converter um float em string.
Arduino: Float to String – aqui está como
Nas instruções que se seguem, assumimos que já definiu uma variável float. Isto pode ser feito, por exemplo, com o comando “float floatvariable = 12.4;”.
Para atribuir a string do float à variável string, basta executar o comando “String stringvariable = String(floatvariable);”
Cuidado: String deve ser escrita com letra inicial maiúscula na declaração.
Desta forma, pode converter facilmente números de vírgula flutuante em cadeias de caracteres e apresentá-los num ecrã, por exemplo.
