Electronics Kits from Radio Shack

Griffin went to Radio shack with Dad and bought two electronics kits. The first kit was for a metal detector. He got very frustrated when it took Mom & Dad several days to help with the soldering. When the kit was complete, it didn't work. Mom and Dad double checked the steps and tried to help with the calibration, but the LED wouldn't even light. Griffin got so annoyed with this project that he decided to put it away for now and move on to the next kit.
The second kit was for a blinking circle of LEDs. This kit had 10 LEDs, resistors, capacitors, and 2 integrated circuits. This kit was easier than the first one, and Griffin did some of the soldering himself. The lights blink around the circle but the switch doesn't seem to do anything. The problem could be with Mom's soldering(the soldering iron is set up for stained glass, not electronics) or it could be a problem with the integrated circuits. Griffin found out that the tiny pins are very delicate. He tried to make sure the IC was plugged in securely, but broke one of the pins in the process.
