![]() if some conditions are met within the microcontroller, the output PB1 is high and through the transistor BC337 a 5V relay gets triggered and a 230Vac signal is sent back to a exterior circuit.microcontroller (ATtiny84A) has 3 input signals of 230Vac (and one 5V pushbutton) that get sensed by HCPL-3700.supply is 230Vac, gets converted to 5Vdc (with RAC03-05SK) and powers the rest of the circuit. ![]() I am creating this post so I can get some tips on how to improve my schematic design (I tried to always keep in mind what is said in the guidelines for circuit design from the FAQ section) and get some validation on the connections of my circuit (from someone who is not a potato like me ) because honestly I would like to know if what I “designed” is at least “functional” so I can order some components and begin testing and prototyping. I am starting my journy in the world of electronics and I would say I am closing on half way through my first project.
