In this project, we create a joystick-controlled laser by connecting two servos to a joystick and using this ... wire directly to Arduino pin 10, as shown in the circuit diagram in Figure 10-4.

Next is the complete schematic diagram of a little Arduino board for your everyday projects. Use the Atmega328P chip, with Arduino bootloader loaded by you, as the brain of this economical circuit.

In order to get his code onto the device he build an Arduino-based communications cable ... He didn’t make up a wiring diagram, but in the code comments [Steve’s] laid out the connections ...
