 		 #177327 - Caution to hobbiest
Responding to: ???'s previous message
Caution to hobbiests. The circuits shown are using the microcontroller(s) directly attached to the MAINS wiring. This can be extremely dangerous unless high focus caution is exercised. Also use care when using other mains attached test equipment to monitor this type of circuit.
