What do micro:pegs do?
In schools, two of the most commonly used small board computers are the Crumble and the micro:bit. Both boards incorporate 4mm holes which serve as terminals for connecting external components.
To simplify the connection of wires to the boards I have invented a simple little device named the micro:peg.
How they work
About a centimetre of insulation is stripped from the end of the wire to be connected. About half of the bare end of the wire is pushed down though the 4mm terminal hole and folded back on itself. A micro:peg is then pushed into the hole to hold the wire firmly in place. Removing the micro:peg releases the wire.
How they help in the classroom
A standard method of connecting components is to use croc to croc leads. These work well but when using them in my lessons I have experienced the following issues:
-
If not connected at right angles to the board they slip off the edge strip.
-
Young children can find it difficult to open the clips far enough to connect them at right angles to the board.
-
If using wired components they add to the lengths of wire which can make the circuit more difficult to follow and understand.
-
If they are not well insulated they can cause short circuits.
