This project based on Arduino, it will measure time of one revolution of wheel, then divide wheel's lenght on this time, and it will be the speed. Revolutions of wheel will be measured by magnet and hall sensor. I used servo motor with arrow and scale to show the speed, it looks like "analog". Also I used 7 segment display to show distance (odometer), also arduino write odo in its EEPROM after bicycle is stopped, so odo keeps in Arduino and not clears after system reboot.You can watch all process of making this device IN THIS VIDEO
Hello everyone!In this instructable I'm going to talk about how you can avoid hard-coding your WiFi credentials into your Arduino sketches using a really awesome library called WiFiManager. It will only take a couple of minutes to go through these steps.Check out the video or continue reading here to find out how to add it and how it works.
This Instructable will actually show you how to make a mechanical glockenspiel as the keys are metal rather than wood (xylophone is a far better word though featuring very underused letter X). This instrument was a part of The Rock Band, composed of instruments that make music with rocks by throwing them through the air, slapping them and making them vibrate. The project was created at Autodesk's awesome Pier 9 digital fabrication workshop as part of their artist in residence program.The rock parts of this instrument are the small pebbles that are launched at the keys. However, any small hard object would probably work. The aluminium keys were fabricated using a water jet cutter. If that tool is not available to you, then wooden keys could be used instead provided that the rest of the design is updated to accommodate their design. The xylophone will be controlled by MIDI s
Tabletop Pull Back Tri-Mode Spring Motor Rolling Chassis is a fully 3D printed rolling chassis having 3 modes of operation, wind, power and coast.My earlier 3D printed windup vehicles used a key or knob to wind the spring. This vehicle uses a floating pinion gear designed to wind the spring when the the vehicle is rapidly rolled backwards. This is the wind mode.Once the spring is wound, releasing the vehicle propels it forward until the spring is depleted of its stored energy. This is the power mode.Finally, after the spring is depleted, a second floating pinion gear disengages the spring motor from the rear axle allowing the vehicle to coast. This is the coast mode.This vehicle does not outperform my earlier designs for distance, but it does illustrate that there's always room for improvement!I probably forgot a file or two or something, so if you have any questions, please fee
This Instructable is competing on contests: "Micro Controller" and "Sensors". If you like it, please give them your vote clicking at the above banner. Thanks a lot! ;-)Let's continuous our IoT exploration, with the NodeMCU. On this tutorial, we will develop a Home Weather Station, where we will display outdoor information as temperature and climate conditions including the present day and a 3 days forecast. Our station will also display indoor information as temperature and air humidity. The above Block diagram gives us a general overview about the project.At bellow video you can see the final project working:
Build an interactive Pac-Man bedside clock, with a touch screen, and animated Pac-Man figures.This cool project is surprisingly simple to make and is a great gift for those nostalgic Pac-Man addicts.As well as being able to interact with the Pac-Man game, you can record a sound of your choice for the alarm.
