I would like to control AC devices with a microcontroller. I found this nice tutorial on how to build a relay based controller. It would work great, but I was wondering, can I replace the relay with something non-mechanical such as a transistor or maybe a solid state relay?
Can a transistor be used in such an application and if so, what is the model number of one that could handle 120V and the current of, say, a 60W incandescent bulb, a hair dryer, etc?
