Hi Everyone,
I am new here let me introduce myself.
I come from an ICT background and recently had the desire to learn electronics, it was not an option for me back at school and as such I only know the very basics.
However I have built a few circuits and learnt the basics of how to use a multimeter and I am really enjoying it.
Now for the question, I have a 5V DC input @ 500ma (from USB) and wish to drop this to run at roughly 3.5 V. I think that I would have to use a voltage Regulator, maybe a LM317? but im not sure
Can anyone help me and tell me what direction to turn in as im getting a bit lost...
Thanks a lot
EDIT: Actually I have just found out about Voltage divider circuits, If I build one of these with a 1ohm + a 2.2ohm resistor according to an online calculator i found it will reduce the voltage to 3.5V so Im going to give this a go.
