I was making a remote fan controller.circuit and programming is finished but there is only one last problem remains.
sometimes circuit some how change speed(increase count on 7 segment and increases speed) without giving any IR signal.
its like IR receiver virtually received a IR signal.I'm driving a stand fan.I'm not sure this is because fan is a inductive load and i have no idea where is the problem
I removed ir sensor and replaced it with push button.with push button i don't have this problem.it seems IR module is generating signals some how.so i replaced it with a new one but it didn't solved the problem.
circuit responds to IR signal properly
I have attached my schematic here.
I use zero cross detector interrupt pic. IR signal is checked using polling.
can someone point me the error and show me a solution?
thanks.
this is the only problem I'm having to finalize my project
