In this chapter, you'll prepare an 840 tie-point solderless breadboard for experimentation (see Figure 13-1). You'll install a battery, power switch, and an LED power indicator. You can use this basic setup over and over again for trying out robot circuits and modules.
Figure 13.1. Solderless breadboard after completed setup
There are a lot of good options available for supplying power to a circuit on a breadboard.
Continuous power is available by attaching the circuit to a wall outlet through an ordinary power adaptor (otherwise known as a wall wart). Replacement adjustable-voltage supplies ...
