Building a NodeBot

Sensors (Inputs e.g. ultrasonic sensor)

Control (Microcontroller = brain)

Actuators (Outputs e.g. motors)

PowerChassis

Example SensorsPHOTO RESISTOR Produces a variable resistance dependant on the amount of incident light.

ULTRASONIC SENSOR Used to detect distance from objects.

PUSHBUTTON Completes a circuit when it is pressed.

Example ActuatorsPIEZO ELEMENT A pulse of current will cause it to click. A stream of pulses will cause it to emit a tone.

RGB LED In Common Cathode RGB LEDs, the longer lead is the common lead which connects to ground. The three other leads are for Red, Green and Blue signal, which can be controlled via PWM on I/O pins.

CONTINUOUS ROTATION SERVO A servo that rotates 360 degrees

Arduino• Microcontroller

co-ordinates robot inputs (sensors) and outputs (actuators)
