Dear all,
I am very very new to this world. I am currently trying to implement a small project.
-I would like to have some help with relay circuits. I have a 3 Vdc current that I want to use to open/close a 12volt circuit that gives energy to a electrical pump. I have tried on internet to buy that ready but I have failed finding out one(i have searched on farnell web site). I do not understand the parts I will have to look for.
-The second think is that I would like to learn how I can downgrade the voltage I get from a source. How I can convert a 6voltage for example to a 4voltage? How the circuit would look like and how each component would be called so to proceed and order them?
I would like to thank you in advance for your reply
Regards
A
