Buy an Axon, Axon II, or Axon Mote and build a great robot, while helping to support SoR.

BTW, theres 9 LEDs and 8 LDRs
Is there any smarter way to make the threshold values auto-adapt to any environment?
You could build a hood over the sensor bar so outside light cant get to the LDRs
About the LDRs, they are slow in response and the ADC conversion also takes time.
QuoteBTW, theres 9 LEDs and 8 LDRs it not necessarry to pair them, the important thing is to have enough detectable light. I think the reason that there is 1 more LED is so that each LDR has a light source on either side. Think about it if say the left LDR didnt have an LED to its left. It would only get 50% of the light that the others are getting along with an inaccurate reading.
