Dagu Rover 5 Explorer Kit and Red Black Spider Problem

I am just starting out trying to build my first robot and purchased the Dagu Rover 5 with Explorer PCB, motor controller and Red Black Spider (Ardunio Mega). The Dagu Explorer PCB has IR LED on each corner with a greed LED and instructions that say the LED will light when the IR LED is active. I have connected a HIGH pin out from the Red Black Spider to one of the signal out pins for the IR LED on the explorer PCB but the green LED does not light - any thoughts on what I might be doing wrong? Thanks, James.

Thanks for your quick replies. Fixed by connecting to the Signal In on the explorer board as recommended!!! James.

The "Signal Out" pins on the explorer board are the output of the sensor, not the output from the Spider. The "Signal In" connections turn on the LEDs. I will update the manual to try and clarify this.

 

"I have connected a HIGH pin out from the Red Black Spider to one of the signal out pins for the IR LED on the explorer PCB"

Connecting an output to another output will not work. Just like magnents, opposites attract.

Can you post a picture of your setup, and your code?
