I'm quite a newbie with Arduino but keen to do what I think will be a easy hack to build an automated propagator with my daughter.
Essentially I want to create a box with some plants inside, hook up an Arduino controller (Uno) and perform the following:
- Monitor temperature (simple, can hook up a temp sensor and use serial monitor)
- When temp drops, switch on a light to increase heat in box (not so simple, reading online gets me confused about voltages etc. I am in Ireland so we have type G power sockets, 230v and frequency 50hz according to Ireland - Power Plugs & Sockets: Travel Adapter Needed?.
- Soil monitor to display a light when the soil is low (easy, already have a project that does this).
So, basically I am really stuck with how to turn a power socket on and off. I've read about relays etc and looked at some instructables articles but most of them seem to be using different voltages etc.
Can anyone recommend a good option for me here?
