Ethereum is about to get another big update. It's called Constantinople and will increase the performance of the network and introduce some new features. It will also delay the difficulty bomb.

Measure distance to an object by using a laser-based Time-of-Flight sensor. These sensors have a range of up to 2 meters and are pretty accurate. You could use these for all sorts of things like measuring waterlevel in a container (without getting the sensor wet). The sensor works by shining a laser onto an object, and timing how long it takes the light to be reflected back to the sensor. ⚡️Other videos in this series: https://www.youtube.com/playlist?list=PLzvRQMJ9HDiQ3OIuBWCEW6yE0S0LUWhGU (Everything you need to know about programming the ESP32 by using the Arduino Framework) ?
