Please add the symbol for LDREE to the EasyEDA Libs with user adjustable `Rmin`, `Rmax` and `tc` values in the Properties panel. >Rmin represents the resistance in Ohms of the LDR when the Vlight_level input = 1V, i.e. maximum illumination; >Rmax represents the resistance in Ohms of the LDR when the Vlight_level input = 0V, i.e. total darkness. >tc represents the time constant of the LDR in s. Default values are: >Rmin = 100 >Rmax = 1Meg >tc = 100m The spice model for LDREE is in the library but does not yet have the correct syntax to accept parameters via the Properties panel. * There are demonstration simulations here: ><https://easyeda.com/file_view_Light-operated-switch_qsKEWewqI.htm> ><https://easyeda.com/file_view_Dark-operated-switch_fgMsYgye8.htm> ><https://easyeda.com/file_view_LDR-test_aXt93XfVP.htm>
