Hi everyone, I'm going to start by saying that electronics are far from my forte, so, please, excuse my ignorance.
I have a motor and I want to build a circuit to control when the motor is turned on/off. I want the motor to be turned on and off based on the movement of a certain object and I plan on using an LED and a photocell to do that. I want a circuit that's set up so that the motor is turned on if that object blocks the LED and it's "dark" and I want it to be off as long as the photocell can detect the light coming off of the LED.
1- I think the voltage coming off of the photocell isn't strong enough to control the motor so I need to amplify that signal (transistor?) but I'm not too sure I know how to do that.
2- how do I make sure that the motor is either on or off without using a digital signal?
3- what other components do I need?
I tried searching on the forum but I couldn't find anything. It is possible, though, that I'm using the wrong terms in the search so, please, feel free to direct me to a thread/an article.
On a side note, what is a good website to buy components off of?
Thanks in advance.
