Arduino Theremin
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.
Description
The Arduino Theremin is a musical instrument that produces different sounds based on the distance of an object from the ultrasonic sensor. The ultrasonic sensor measures the distance of the object and sends the data to the Arduino. The Arduino processes this data and generates corresponding sound frequencies through the speaker. The pitch of the sound changes based on the distance, similar to how a traditional theremin works. This project combines music and sensor-based interaction to create a fun and creative experience.

A solar-based LED system is a lighting setup that uses solar energy to power LED (Light Emitting Diode) lights. During the day, a solar panel captures sunlight and converts it into electrical energy, which is stored in a battery. At night or in low-light conditions, this stored energy powers the LED light.
These systems are eco-friendly, cost-effective, and ideal for off-grid or outdoor applications like street lighting, garden lights, and emergency lighting.

A Flip-Flop LED Flasher is a simple electronic circuit that alternately turns two LEDs on and off in a continuous loop, creating a blinking or “flashing” effect. It’s commonly built using transistors, resistors, capacitors, and LEDs, forming an astable multivibrator — a basic circuit that oscillates between two states without any external triggering.
It’s often used for decoration, indicators, or learning basic electronics.
