Hi everyone, did you watch our Selamat Hari Raya Aidilfitri 2015 video? In that video I use Cytron RainbowBit to make the colourful plate. The number of the RainbowBit that light up is controlled by the analog distance sensor. When the analog distance sensor detect the object nearer, more RainbowBit will light up and when the distance is less than or equal to 20 cm, all the RaibowBit will light up and make a beautiful cycle of colours.

Cytron received an inquiry from our precious customer today. The question is about measuring water level using Analog Distance Sensor (SN-GP2Y0A21). He (i think is a ‘he’) asked whether the infrared beam will penetrate the water, or instead, reflect by the water surface. That’s an interesting question which has never come over my mind. So I decided to conduct a quick experiment after my lunch.
