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.
What can we do with a UC00A besides Serial to USB converter? Let’s start from fulfilling my day dreams. I always wanted to have a device other than mouse and keyboard to control my PC. Okay, it’s not a big deal if we use a microcontroller to commnunicate with the PC through serial interface by using a UC00A. However that’s not what we want to achieve here. We want to do it by using UC00A alone!
