Coil L1 isn't critical (it just decouples the power supply), but coil L2, and the T1 transistor, and C2, are matched to the antenna; you'll want to scale L2 and C2 up slightly from the 433 MHz values, and change the antenna length (lengthen it) for the lower frequency. An Arduino board will be connected to a 433 MHz transmitter and will send the âHello World!â message. However, if their functionality is classical and basic such as door sensing/ smoke .
