I am currently trying to build an infrared bicycle alarm circuit as attached in the picture, before building and commisioning this circuit I want to simlulate it. Multisim is the simulation package that is avaiblible as my colelge but I am having a problem with building this circuit since as it does not have the infrared reciever (TSOP1738) what can i replace it with or what other good simulation packages are there that I can download?
