Overview

The purpose of our project is to construct a robot that can be controlled by hand movements with several other add-ons, like numerous LED's and a speaker which plays a song.

Components Needed

• mBed LPC1768 (2)
  

• Zigbee (XB Series 2) (2)
  
• Emgreat Robot Chassis (Includes 2 DC motors, chassis, and battery pack)
  

• Red LED's (2)
  

• Speaker
  

• Class D Audio Amp
  

• MCP 230S17 Microchip (3)
  

• RGB Led (16)
  

• Ultrasonic Sensor (2)
  

Wiring Diagrams

For each Mbed, a visual overview is included first to give an easy overview of how the entire Mbed is pinned out the various components. Following this general overview are the various pin outs for specific components, as well as any general reminders for that specific part (ex: attaching a resistor in series with an LED).

Mbed 1

Mbed1 is solely responsible for interpreting the users hand gestures and transmitting the appropriate command to Mbed2 using one of the Zigbees.

Visual Overview

The visual overview is provided below, and is a nice way to quickly reference the various hookups to Mbed1 to ensure that the general wiring is correct.

Zigbee Connections

H Bridge Connections

LED Connections

Don't forget to connect the LEDs in series with a 100-300 ohm resistor to prevent risking burning them out.

MCP23S17

The MCP23S17s are responsible for controlling all of the RGB LEDs, allowing the car to have more than would be possible with just the MBed.
