What is the difference between a Hall effect sensor and an inductive one?

From what I have read, when placed within a magnetic field, a current will flow in both sensors. My goal is to use this kind of sensors to guide a robot thanks to an existing automower loop wire, such as suggested in DIY Perimeter Wire Generator and…

Controlling multiple 24V solenoids with Arduino

I'm building a pump for which I need 4 medium strength solenoids (20-50N). 24V is probably the minimum I will need to put through them, but this is something I need to test, once I've got them working. At 24V they draw 400mA. I've found various…
