The Matrix Candle shows a realistic flame one two LED matrices. It's been powered by a LiPo battery. The brightness can be set in five different levels. To start the animation simply press the button. To change the brightness, press it again for a short time. To turn it off, press the button longer. The battery lasts more than 24 hours depending on the brightness and can be recharged by USB.
actually think I like V1.0 better. Better aesthetic... great gift project for student to assemble.... thanks for sharing!
