![]() This work will provide an introduction to the FreeCAD code base and the use of supporting software such as OpenCascade and Qt. Work must be repeated, for example in creating a Dimension in a drawing when the corresponding measurement already exists in the 3D model.New users find the diversity of measuring tools confusing.Individual workbenches have created measurement tools that filled the needs of that workbench only.A single method of measuring objects would smooth workflow and reduce learning time. There are currently several ways of measuring objects in FreeCAD: Draft Dimensions, TechDraw Dimensions, Manipulator Caliper, Measure Distance, Measure Linear, etc. PCBWay is offering FR-4 & Aluminum boards in addition to advanced PCBs like Flexible & Rigid-Flex boards, HDI, and Rogers at a very reasonable price.This page is describes a potential Google Summer of Code project regarding upgrades to FreeCAD's measurement functions. PCB WAY is well known for offering high-quality Printed circuit boards at a very budget friendly price to build many interesting electronics projects. You can check the video on how to use this distance-measuring device hereĭon’t miss to check our previous post on making a Wi-Fi Rover Controlled by SmartphoneĪmazing PCBWAY Circuit Boards You should try ![]() Working video of Distance Measurement Using Nodemcu and HC-SR04 You can also cross-check these values using a normal scale/ruler.Hold it still until the numbers are stable on OLED.Now bring the sensor in front of the object where the distance needs to be measured.Just plug in to any USB-powered source.This is a plug-and-play type of device.How to use Nodemcu Powered Distance Measuring Meter Nodemcu is combined with the ultrasonic sensor in our project.Īs we know HC-SR04 boards can measure range as they emit ultrasonic waves. The logic behind the Range Sensor or Ultrasonic Sensor We are not using Wi-Fi here at the moment.īut in the future, we can convert this project into an IoT project, More on this later. Pocket-friendly board that has built-in wifi to build cool projects. Nodemcu is one of the popular microcontrollers that has great features. Sounds interesting right? Yes, it is! we will make a project as we spoke about above. How cool is it to measure the distance and not have the need to read the values manually? Nobody likes the very old way of distance measuring, like the most widely used using scale! With the improving technology everybody like to stay ahead of others. It’s very useful when we have a need to find out the distance to do some calculations.įor example, if you want to buy a table for your bedroom you should be aware of space availability.īy measuring the distance in advance you can plan for the size of the table that fits best. It’s nothing but the distance between 2 objects. This is a very basic question that most of us hear or few already know about this. To begin with, let us go through some of the pre-requits of this project. HC-SR04 or in other words distance sensor is the component that plays main role in our project. In this project, we are making a scale or short-range sensing device using Nodemcu and an ultrasonic sensor. Arduino Uno Super Starter Kit Ultrasonic Sensor
