Today I will share how to make a WIFI JOYSTICK from an ESP8266 and 4 ways industrial joystick. It can be integrated into the factory’s automation system or be used for smart home control. The mentioned control systems are PLCs and the specific case that I am applying is SIEMENS PLC S7-300….. Let’s start and

Which uses more water – a bath or a shower? I was recently thinking about this question, and I realized that I don’t actually know how much water is used when I shower. I know when I’m in the shower sometimes my mind wanders, thinking about a cool new projects idea or trying to decide

The inverted pendulum is a classic problem in dynamics and control theory that is generally elaborated in high-school and undergraduate physics or math courses. Being a math and science enthusiast myself, I decided to try and implement the concepts that I learned during my classes to build an inverted pendulum. Applying such concepts in real life not

What are we building? Humans can’t detect magnetic fields, but we use devices that rely on magnets all the time. Motors, compasses, rotation sensors, and wind turbines, for example, all require magnets for operation. This tutorial describes how to build an Arduino based magnetometer that senses magnetic field using three Hall effect sensors. The magnetic

Introduction: On one of my weekly pilgrimages to Lowes (as any devout Kansan does), I found a sad little plant in the Gardening Department: a Janet Craig Compacta. The poor little guy looked lonely and dehydrated. We clicked right away and immediately I knew I had to take him under my wing. There was one

The brachistochrone curve is a classic physics problem, that derives the fastest path between two points A and B which are at different elevations. Although this problem might seem simple it offers a counter-intuitive result and thus is fascinating to watch. In this instructables one will learn about the theoretical problem, develop the solution and finally build

I have in my hand a distance laser sensor with high precision and speed. It is used in industrial environments for object positioning or detection applications. According to technical documents, I found it can communicate with other devices via RS485. I spent the weekend to learn it and find ways to communicate with cheap CPU

I designed and built a Geiger Counter – a device that can detect ionizing radiation and warn its user of dangerous ambient radiation levels with the all-too-familiar clicking noise. It can also be used when scouting for minerals to see if the rock you found has Uranium Ore in it! There are many existing kits

This is a simple arduino project to make a electronic die. It is possible to choose for 1 to 6 dice or 1 out of 8 special dice. Choice is made by simply turning a rotary encoder. These are the features: 1 die: showing big dots 2-6 dice: showing dots as well as total value
E-dice – Arduino Die/dice 1 to 6 Dice + D4, D5, D8, D10, D12, D20, D24 and D30 Continue Reading
In this project, we will be making a benchtop pH meter using the gravity analog pH circuit and probe from Atlas Scientific and an Arduino Uno. Readings will be displayed on a liquid crystal display (LCD). MATERIALS 1 – Arduino Uno 1 – Gravity analog pH sensor 1 – pH probe 1 – 20×4 LCD module 1 – 158x90x60mm Enclosure
