Solderless breadboard
A board full of holes with metal clips inside: push legs and wires in to connect them, no soldering.

2Use it
| Pin or leg | What it is for |
|---|---|
| a to e, f to j | the 5 holes of a column are joined; the middle gap keeps the two halves apart |
| + and - rails | long lines along the sides: + for power, - for GND |
- Put each leg of a part in its own column, or the legs are joined to each other.
- Use the + rail for power and the - rail for GND.
- On some long boards the rails stop in the middle: join the two halves with a wire.
