I'm mechanical engineer with poor knowledge on electronics and programming, but i'm really curious about and would like to learn. I have basic knowledge on arduino.
My project, I think very simple for you, is the following:
I have build my house near Paris and i'm finishing the kitchen. One of my friends gave me a kitchen hood, and I opened it to get the motors and fan to make a custom one, integrated in my custom furniture.
The motor has 5 wire : one for the neutral, and 4 for the 4 speeds levels : high / mid-high / mid-low / low. When you connect the 220V to he high speed wire, you get a high aspiration. Quite easy to understand.
I would like to use a push button to control the hood : one push -> Low speed, another push -> medium speed, etc. And why not a long push to turn it off.
My idea is to use 4 electric relays connected on each wire, and make a program on arduino to control each relay depending on number of push from the push button.
Do you think it is a safe way and a good way to make this ?
Do you have better idea, or advice to make it in a safe way ?
which kind of relay should I use, and is there any advice on how to use and mount it ?
Thanks in advance for your feedbacks,
