As touchless control devices and interactive technology become increasingly widespread, light sensing, distance sensing, and gesture recognition technologies are progressively playing crucial roles in microcontroller application domain. Light sensing that detects light intensity is used in environmental monitoring, lighting systems, etc. Distance sensing accurately measures the distance between objects and sensors, widely applicable in automation and robotics. Gesture recognition allows devices to identify human gestures, applicable in interactive technology, smart home devices, etc.
This example code utilizes Sensortek's “Proximity with Ambient Light Sensor” chip - STK3420, demonstrating how to get gesture values from this sensor using the I²C protocol.
