Rishabh Jain’s Calm Pulse Turns an Espressif ESP32-C6 Into a Guided Respiration Train Gadget

Maker Rishabh Jain, often known as “Mr_Electronaut,” has designed a compact gadget that goals to ease anxiousness and calm your respiration — by strolling you thru a guided respiration train through glowing LEDs and tactile vibrations.

“I’ve always felt nervous in situations like public speaking, presenting ideas in office meetings, or trying adventurous activities,” Jain explains of the inspiration behind the Calm Pulse. “In those moments, my heart starts racing and my breathing becomes fast and shallow, making it difficult to stay calm and focused. Many breathing techniques are known to reduce anxiety, but during stressful moments it can be hard to remember the rhythm or stay focused long enough to follow them. This inspired me to create Calm Pulse — an Anxiety & Stress Reliever device. Using gentle light patterns and vibration, the device guides the user’s breathing rhythm and helps bring the body back to a calm and balanced state.”

The pocket-friendly gadget is constructed round a Seeed Studio XIAO ESP32-C6, certainly one of a rising household of compact breadboard-friendly growth boards. This explicit variant options Espressif’s ESP32-C6 mcirocontroller, although its wi-fi connectivity goes unused right here — it is easy there to learn the enter from a push-button swap and set off certainly one of three guided respiration workout routines.

Once triggered, the chosen guided respiration train — a four-second in, four-second maintain, six-second out sample for rest, four-four-four for focus, or three-three-four for “panic mode” designed to calm you down from heightened anxiousness — performs out on an eight-count RGB LED ring, with a vibration motor including additional suggestions even when the person’s eyes are closed. Power comes courtesy of a small lithium-polymer pillow battery, with all the things squeezed right into a small plastic case with a gap reduce out for the swap.

“Building this device was a meaningful project that combines technology with a simple yet powerful idea: helping people regain calm through guided breathing,” Jain says. “By using synchronized light patterns and gentle vibration feedback, the device provides an intuitive way to slow down breathing and manage stress or anxiety in everyday situations.”
