Comando por radio
-
Queria saber como puedo hacer un circuito que permita ejecutar un comando por radio, aver si consigo explicarme…
Se trata de fabricar un pequeño emisor y un pequeño receptor, de manera que, cuando en el emisor pulso un pulsador o interruptor, se envie una señal por radio al receptor (hasta que dejes de pulsarlo) y en el receptor se encienda un led o active un relé.
Tiene que tener un alcance minimo de 250 metros atravesando paredes
