Ask an Expert Topic Forum: Grades K-5: Physical Science

Modifying the Light-tracking bristlebot Modifying the Light-tracking bristlebot We have successfully built the light-tracking bristlebot. It was such a fun project! Will the circuit work if we replace the photoresistor with an IR sensor to make a heat-tracking bristlebot that will detect the warmth of a hand? Thank you! Re: Modifying the Light-tracking bristlebot Hi, There are different types of IR sensors, so in general it is not a matter of simply swapping out the photoresistor for an IR… Read more
