So use your common sense if you put it into use, and let me know if you got some security/stability improvements. 🙂 What is this? This is a cheap way of making some simple home automation, so far this […]

When looking at tutorials you might have encountered pull-up or pull-down resistors, but why are they needed? If you look at your arduino micro controller and upload something like this and then takes a look in the serial monitor, you will see something like and so on, totally random and might give more 1’s than 0’s if you move your hand closer to it.

After multiple times having problems connecting external DC power supplies, I started to solder the connectors onto pin headers in different ways. The most stable solution so far is this. And if it is put in like I did, a little in on the breadboard power rail, the surface of the breadboard help support it.
