    • RE: Question: FL5150 LED Dimmer - replace a analog potentiometer with a digital one

      @jimmyjames

      Hi,
      Hi everyone,

      I'm creating a project that will dim light circuits from a esp32 in trailing edge . I am very cautious about 240vac mixed in with low voltage.
      So im thinking about using this FL5150.
      FL5150 5 volts PS will be supplied from a 5 volt regulator circuit designed to be on the AC side with FL5150. Should be straight forward.
      Next use 4 opto couplers across a series R network to produce a DAC. So you have 4 bit to analog out. This gives me galvanic isolation from AC.
      4 bits gives 16 steps of voltage to Dim control line on FL5150.
      Would be very cheap in parts and piece of mind with separation on esp32 and AC.
      Any ideas if I'm on the right track ?
