| DIP packages [0], the circuits can be built on breadboards [1]
| since the pins can be inserted directly into the holes of the
| breadboards. If you are new to this then you can find an overview
| of electronic symbols in Wikipedia [2] for example - this is
| helpful because it gives you names and terms to search for.

| Having even a cheap multimeter to measure voltages, resistances

| don't use these to measure line/mains power - even if they claim
| to be able to do that).

| Have fun!

| primitive.
