Proximity Sensor Bit

BIT DESCRIPTION

You might have noticed a pink Bit in your kit called the proximity sensor. This Bit has the power to sense objects around it without physically touching them and make something happen.

HOW IT WORKS

The proximity sensor Bit emits a beam of infrared light which the human eye can not see. When this beam of light hits an object, it gets reflected back on a small sensor on your Bit. More light reflecting back to the sensor equates to a stronger signal sent by the proximity sensor Bit to the output Bits that follow it to the right.

PROXIMITY SENSOR AND REPRESENTATION ON THE APP

You can see the strength of the signal generated by the proximity sensor Bit on the bar graph on your littleBits Droid Inventor app. These controls can be found in missions that use the proximity sensor Bit like Force Mode, Self Navigation, Intruder Alarm, and Arm Wave. On the bar graph, If the signal goes above the small red arrow, this means that the proximity sensor Bit is activated. The higher the bar, the stronger the signal, and vice versa.

HOW TO GET THE BEST PERFORMANCE OUT OF THE PROXIMITY SENSOR BIT

The material, color, and distance of the object in front of the proximity sensor Bit affect how it works. Shiny and light-colored surfaces close to the proximity sensor Bit reflect more light and will generate stronger signals compared to dark and rough surfaces kept farther away.
