It is a common phenomenon that the single row seats on Arduino will in poor connection when we use the Arduino board for a long time. Most of the time, we will find the shield can’t work well when we plug the shield, we may think there is a problem with our code, in fact it is the same code as we used before. We can’t help but suspect maybe there is a problem with our hardware. We may think the poor connection. We can use a soldering iron to remove the old one and transform a new one, but this is much trouble to do that, and easy damage the pads.
Following I will show a sample way to solve the poor connection of Arduino.
1. 1 x Forceps
2. 1 x Plywood knife
1. Pry up the transposon of the row mother with a knife carefully
2. Correct the inside pin with the clamp, then tight it.
3. Buckle the transposon to the row pin, according to the way to correct the rest of the transposon, and your Arduino will reply as ever.
