Electricity Labs
This week we used our Arduino kit to build our very first circuit using a breadboard, resistor, and USB power.
I initially put the basic circuit together and couldn’t get it to work. Luckily my friend Dana was sitting down the table and quickly pointed out that I didn’t have the right resistor. I knew that different color resistors had different ratings, but I didn’t realize that you had to look really closely at the little stripes. So, I thought all of my resistors were the same rating at first.
