I wanted to buy an Arduino board and now I have a question:
How many lamps can I connect to an arduino mega 2560 ?
Can I really connect 54 lamps with an arduino ?
And another question is...
How many volts can I use for the board (max.) ?
Over 10 Volt or is it to high voltage ?
Well....I will happy when i get a good answer !
(sry my english isn' t so good)
Above you can see that, the max voltage is 20V, recommended max is 12V, but you can use relays to control higher voltages and lamps.
You can [u]control[/u] 54 pins. That means you can connect 1 or 10 lamps on 1 pin and turn them on and off simultaneously (in the same time).
in a glance, if you become more specific about those lamps maybe i can help you further.
Thank you for your answer !!!
When I need help I will ask you ;)
Why did you create a poll?
Max I/O per pin is 40mA. Total max current of the Mega2560 is around 200mA. So it depends on how much current your devices draw. Generally you'll need a transistor connected to the I/O pin to drive a load.
Ouhh ! Sorry ! I am new here and I didn't know how to do a quote ;D
Thank you !
I will show how much mA I need !
