How to read the holes.
  1. The two long lines at the top and bottom are the power rails. Everything along a red + line is joined together; so is everything along a blue − line.
  2. In the middle, holes are joined in columns of five — A to E is one group, F to J is another. Column 7’s A-to-E holes are all the same electrical point.
  3. The dashed centre channel separates the two halves — that is where a chip sits, legs straddling the gap.
  4. A resistor and an LED must go in different columns — same column and the current skips the resistor entirely.
