interface sensers with ATMEGA32 by kamaljamesbond

[query]

i want to interface sensers ( LDR ) how i will interface it with ATMEGA32 also send me the code. & circuit diagram

Hi there

You will need to use an ADC present inside AtMega 32. Circuit for LDR sensor is quite simple; make a two-resistor voltage divider circuit with one of its resistor being LDR and take their point of joining to be the alanog input for ADC pin.

Here is a similar project on EG, check this out:

Good luck
