Voltage For Project

Greetings everyone,

I am new to the arduino community. I am currently working in a project involving the arduino mega 2560 R3. I am wondering if it would be able to handle all the components that are planned to connect. These include:

2 Peristaltic pumps (one 5V, another 12V)
2 pH sensors (3.3V - 5V)
Flow meter (5V)
LCD 2IC (3.3V - 5V)

I am aware that for the 12V I'll need an external power supply. Not sure if you'd recommend a particular adapter or if I could just use a converter to 7V-12V. I also have concerns if a 400 tie-points would be able to fit all the connections.

My apologies in advanced if this topic is not in the right board.

  • Yes

  • Loads that are more than 20mA require you to use drivers . . .

You're new and that's okey. However Your words make no sense.
Please grab pen, paper and make a drawing of the build You aim at.
Rule number one: Never think about the controller as a power supply for more then a LED or two.
Rule number two: No voltage higher than 5 volt is handled by the controller. If higher voltages are use some kind of driver is needed.

Hi, @hc_aoe
Welcome to the forum.

You will need some simple drivers for the pumps.

A 12V supply with a 12V to 5V DC-DC converter would be better.

What do you mean?

Can you please tell us your electronics, hardware experience?

Thanks.. Tom... :smiley: :+1: :coffee: :australia:

Do you still need help?
