Right sensor not working in Picaxe Micromouse kit!!!

[bugmenot1234]

Hello there pplz of forum, I am constructing micromouse from Picaxe. I came across a problem, that after finishing the construction part and loading up the test programs provided with the kit, I came to know that my right sensorLED is not glowing when I place a wall on right hand side of the sensor. The front and the left sensors are working perfectly as well as the motors and relay. But the right sensor is not detecting the wall. PLZ HELP!!!!!!!!!!!!

I know you've probaly already tried this but:
Check all of your board for shorts and damage to traces.
Check the code to see if you may have deleted a bit
Get out a digital camera and see if you can see a blue light from the LED
Are there any unfilled holes in your board?

Do you have the LED mounted the right way around?

There should be a small flat around the rear rim (leg at that side is the Cathode) and from the datasheet images and info, that should be to the front of the mouse.

Thank you sir for your guidance. But I have tested all these things and I came to knw that my IR emitter LED are working perfectly but the IR sensor may not be working. Can you tel me what is the model number of the the IR sensors given with the kit? and if posssible can you tel me where can i find the datasheet of the IR sensor? If I am not able to find the same sensor in the local market, can you tel me any other replacement of the IR sensor having same properties as the IR sensor given with the kit!!!
Thank you!!

See this device whihc the Rev Ed on-line store sells:
http://81.134.141.187/epages/Store.storefront/?ObjectPath=/Shops/Store.TechSupplies/Products/LED020

More specifically believe it is the TSOP1838 for 38kHz detection.

I do not know your location (makes it hard to make a recommendation)'but here in Australia
Altronics sell: http://www.altronics.com.au/index.asp?area=item&id=Z1611

and

Thank you sir it really helped!!!

Are you sure, I thought hey used some other sensor. A TSL260R, which is an infrared light to voltage sensor. This looks like a better match to the profile of the photographs on the datasheet.

Best waiting until we get the response from Technical

Best regards,

Oh Oh,

Yes, On reading deeper into the KIT110 instructions it states:
"Light to Voltage Converters x3".

But does not state a part no.

So the TSL260R you mention is a likely candidate.
http://www.digchip.com/datasheets/parts/datasheet/470/TSL260R-pdf.php

Further into the micromouse datasheet it does discuss READADC commands for testing.

TSL262R-LF
e.g. Farnell part 118-2351

Thankyou sir for the info.
I also wana know the part number of the phototransistor that has been used in the wheel encoder for counting the wheel count.?????
