Photo phobic robot will sense the light and will try to move away from light. On the contrary photo phobic is exactly opposite where it does not follow the light or more precisely it avoids and goes to places where there is less light
An Arduino Theremin using Arduino, an ultrasonic sensor, and a speaker that produces varying sound pitches based on the distance of an object from the sensor.
To measure distance using an ultrasonic sensor and display the result on an LCD with an 8051 microcontroller, you’ll need to interface several components: an ultrasonic sensor (e.g., HC-SR04), an LCD (e.g., 16×2), and the 8051 microcontroller.
