Hello, this is my first "project" so please keep that in mind when answering my question's!
Basically, I want to set up a circuit with an LED and Motor in. The details of which can be found below.
The power supply is simply a 9v Battery which is connected to a switch. This is connected to an LED light with a forward voltage of 2.2v and current of 20mA. Connected to this is a propeller motor with a voltage of 3.7v and current of 100mA. By the way, the circuit is set up in series. My question's are as follows;
1. What resistor will I need to have in the circuit with some explanation?
(I have bought a pack of 1000+ different value resistors at 1/4W)
2. What resistor would I need if I included another LED in the circuit?
Thanks in advance!
