Hi,
I am interested in the sensors found on the formula flowcode buggy. In the circuit diagram, the circuit for the IR sensors have been well explained and referenced (TSAL 5100). But, I would like to get the datasheets for the microphone and the LDR also please. And could you please explain how they work?
Thank you.

Re: LDR and MIC datasheet
Hi
The LDR and microphone are generic parts.
The microphone is of the electret type and is powered via R26, it has a pre-amplifier for input to the microcontroller ADC.
The LDR is a resistor whose resistance decreases with increasing light intensity.
For more comprehensive details on how they work I suggest you search articles such as those on Wikipedia.
For details of typical parts, for example, MIC: Rapid 35-0192, LDR: Rapid 58-0134 at http://www.rapidonline.com/
Hope that is of help to you,
Regards,
Leigh
