I am new and glad to know about Arduino. Lately I am building my project which used solenoid.
I bought a solenoid which is spec at 24V 3.5W. It drained about 140mA @ 24V.
However, I do not have any 24V adapter available at home. Instead, I plan to use my laptop charger, which is rated @ 19V, 4A.
I understand a 4A is too high (plan to use a fuse). Could anyone advise if there is any negative impact on using 19V to drive 24V solenoid?
Thanks in advance.
