1. A power tool, comprising:
a chuck having a distal end configured to secure a tool; and
a motor configured to rotate the chuck and the tool secured to the chuck;
a first position sensor configured to sense and measure a first distance between the first position sensor and a workpiece, and generate a first signal that is indicative of the first distance;
a second position sensor configured to sense and measure a second distance between the second position sensor and the workpiece, and generate a second signal that is indicative of the second distance; and
a controller configured to:
store previously measured first and second distances;
compare each of the measured first and the second distances with corresponding previously stored and measured first and second distances;
generate a percent difference between the measured first distance and the corresponding previously stored and measured first distance and/or between the measured second distance and the previously stored and measured second distance; and retain the measured first distance and/or measured second distance only if the percent difference is less than or equal to a threshold percentage;
cause the first position sensor and/or the second position sensor to project a blinking pattern that conveys a warning message to a user of the power tool;
determine, based on the first signal and the second signal, a measurement of a drive depth of the tool into the workpiece; and
generate, based on the measurement, an indication of drive depth as each predetermined interval of drive depth is reached.
