This is my first instructables, sorry if there are any mistakes here.
Objective: I will teach you how to activate an LED with an magnetic.
Step 1: Materials
1) mini reed
5) any power source(you can use the Arduino)
Step 2: Instructions:
First, connect the power source to the protoboard.
Then, connect the mini reed to the negative end of the protoboard.
Now connect the anode (+) of the LED to the protoboard and the cathode (-) to the right pin of the mini reed.
Step 4: IT'S DONE!!
just put an magnetic near to the mini feed and the LED will work.
(Sorry if you can't see anything in the photo, it's really difficult to take a photo with an LED on!)
If you have any questions, just ask me in the comments.
