NEW! Sensei, the I2C scanner saved me HOURS of debugging! My MPU6050 was at 0x69 not 0x68! The Oracle was RIGHT. Thank you for this amazing site! I'm building a self-balancing robot!

Rating: ⭐⭐⭐⭐⭐ (5/5 — The Oracle is all-knowing!)

My garden has never been better monitored! The DHT22 + LM35 combo is perfect for my greenhouse project. The Dojo lessons were clear and easy to follow. Sensei, you have a student for life! Also, my tomatoes LOVE sensors.

I'm 11 years old and this is the COOLEST website EVER! The sensei theme makes learning so fun. I finally understand I2C thanks to The Scroll! My mom says I talk too much about sensors now. She's cool with it (mostly).

As an electrical engineering professor, I've bookmarked this site for my classroom. The SensorSensei approach to teaching sensors is genuinely pedagogically sound. The martial arts theme is a delightful cherry on top. Excellent work!

AS A WEBMASTER FROM 1998, this site BRINGS ME HOME. The tables layout! The marquee! The visitor counter! The GIFS! I'm getting emotional. Also the sensor content is solid. You've captured the soul of the old web AND teach something meaningful. GENIUS.

Sensei, I burned my first MPU6050 just like you said. Then I bought a level shifter and it worked. I feel like I've grown as a person. Also I hope your Valentine's Day is filled with clean I2C signals and stable 3.3V rails. 💜
