this relay model for radio frequency communication,
was ultilizado the BC 458 transistors put attention
to ca put the transistor to be oinvertido the base
and the emitter , because at the time I had not paid
attention to the wiring diagram was wrong, the
issuer must be grounded and the collector voltage 5VDC list of components :
R1 R2 R3 1k BC458 Q3 Q1 Q2 U1 Atmega 328 D1 D2 D3 1N4148
