Problem: I want to try to assemble a circuit that would turn a light bulb (230V) on and off, controlled remotely by a PC. Ideally, the control will be over WiFi, next in line is Bluetooth and least preferable are RF and IR. Cost is a consideration and it would really be nice to be able to manage in 50-100$ total (including a newbie's kit).
About me: I'm a programmer and a total noobie to electronics. I want to learn to do such things. I also want my home lights to be controlled from a smartphone.
- Where to start? What should I know about electronics?
- I've read about Arduino, is this what I need?
- What components should I buy?
- How much should it all cost?
