This 'digital timer' project is very cheap - you can find an amazing completely programmable digital wall timer for $25 on Amazon, or same price in Home Depot.
I want to play with Arduino since I'm a Computer Science major (Neuroscience as well), and I have been learning about this stuff in my Digital Electronics II class.
We are using Prototyping boards, writing code, and then demonstrating the project.
But I want to experiment with Arduino and a good project to start would be a small on-off digital timer.
I know this is possible, but is an Arduino something to use for this project? I would need a relay module or something to handle a large water heater. Would this work? I saw people use Arduino's for a greenhouse, and he could open the screens based on the temperature, sunlight, etc. So this is essentially high amperage like a water heater.
I guess my question is, would it work? Also, what would I need? Is a Relay Module enough to power this high amperage? OR, use a relay module to control a larger relay or breaker? Right now, the water heater is direct to the breaker panel, and at a breaker switch.
Maybe this is a project for a simple $25 digital timer. :(
I'd like to have an override switch (HTML web page is okay) and then on a daily timer, easily configuring the days, etc. The honeywell digital timer can do all of this, and is quite small.
Hopefully I can find helpful advice.
