My first robot

Newbie here

Hi every one i have been member for a while now and have finally collected all the parts needed to complete fritz start here robot.

Every thing is the same apart from im using a 28x2 picaxe instead of the 28x1 picaxe,also using the ultrasonic sensor pictured above instead of the SRF05.

i have followed the walk  through on https://www.robotshop.com/letsmakerobots/node/66  for the SRF05 sensor and translated the wires to my sensor as followed:

wire             srf05                mine

black           ground 0v         gnd

blue             trigger input      trigger

yellow          echo output      echo

red               5v supply          vcc

i also used the basic program from   https://www.robotshop.com/letsmakerobots/node/66 and nothin happens????????

here is the spec for the sensor:

Description:

  • The modules includes ultrasonic transmitters, receiver and control circuit
  • Its stable performance and high ranging accuracy make it a popular module in electronic market
  • There are 5 pins out of the module, VCC, Trig, Echo, GND and OUT
  • Best performance in 30 degrees angle
  • Electronic brick compatible interface
  • Dual transducer
  • Arduino library ready

Specifications:

  • Voltage: DC 5V
  • Current: 15mA
  • Ultrasonic Frequency: 40K Hz
  • Maximal Range: 400cm / 13 feet
  • Minimal Range: 3cm
  • Resolution: 1cm

i am hoping some one can point me in the right direction.
