I am new to Arduino ,
I need an Arduino to start treatment cycle
- Programme the output controller to auto switch polarity (- to +) after 10 minutes
- During each cycle voltage should control the voltage (6v to 24v) interval 1 minute
These are the steps
1- Switch on manually
2- Programme Arduino to show countdown Digital LED Counter
3- Start from 6 volts leg A out 1 (- ), leg B out
4- Interval volt increasing each minute (6v, 12v, 18v, 24)
5- Hold Current at 24v to complete the first cycle and complete the 100 minutes cycle
6- 3 Beeps to indicate cycle completed
7- Switch polarity and change voltage to 6v ( Repeat steps 4, 5, 6,)
8- Program end
Whoever have electronics ideas will be helpful to share
- How to connect the output voltage controller
- How to with polarity switch
- Do I need one Arduino or Two of Them
Please don't post the same thing in multiple places.
Post once, have some patience across the world, give folks a chance to reply.

I would start with a 24V supply and buck converters for 18, 12 and 6V supplies. If you are working with low currents then linear regulators could be used for the lower voltages. Since you are working with voltages higher than 5V you will need some way to switch the voltages. I would recommend relays as they are cheap and easy to use.
One SPDT relay can select between 6V and 12V supplies. Another can select between 18V and 24V supplies. Those two relays can be driven by the same signal or a single DPDT relay can be used. A third relay, driven by a second signal, can select between the outputs from the first two relays. That would allow two outputs to select between the four voltages. A DPDT relay (or two SPDT relays) can then select the polarity: which output is + and which is -. Total: 5 SPDT relays or 2 DPDT and one SPDT. Or 3 DPDT (where one pole of one relay is not used.
I think your talking to a bot.

That is just a vague description of a project. You will need to develop it more yourself and report specific issues with the hardware and code you write to operate the project. As long as it is just an "idea" it may not generate much interest.
