Zener Diode Tester is controlled by Arduino Nano. Tester measure breakdown Zener voltage for diodes from 1.8V to 48V. Dissipation power of measured diodes could be from 250mW to a few Watts. Measuring is simple, just connect diode and press button START. Arduino Nano gradually connect range of voltages from lower to higher, in four […]
I made a weather station connected to internet. It measures temperature, humidity, pressure, rainfall, wind speed, UV index and it calculates few more important meteorological values. It then sends this data to weathercloud.net, which has nice graphics and UX. It also has a weather webcamera. It cost me around 140€. I made this station as my […]
Making reverse loops can help in model train layouts to change the direction of trains, which cannot be done with turntables. In this way, you can create single-track layouts with a reverse loop on each end to run trains without any pause or interruption. So, without further ado, let’s get started! Step 1: Gather All the […]
This is a radar, designed to detect the distance and direction an object is from the ultrasonic sensor. With the ultrasonic sensor connected to a servo, it has the ability to rotate 180 degress, similar to a radar utilised to detect the position of planes. As the radar wasn’t my original idea, I have also […]
Hello internet people, This is gonna be about how to make what DEFINITELY isn’t a rip off of a mobile game on an arduino uno r3. so to start, your gonna need all the parts, which are as follows!1x Arduino Uno r3 ($42) 2x LCD Keypad Shield ($19 each) 5x buttons 5x 220Ω resistors 28x wires Alright, once you’ve got all […]
In this instructable we’ll be making some centrally controlled wireless RGB lamps, that responds to music and sounds in the environment! In addition to instructions, the instructable contains: Schematics List of components Link to the code so you can make and modify your own project Step 1: Planning Ahead Here are the major components I […]
Since runners often need to track not only their total mileage, but also the distance run on each pair of shoes (in order to know when to replace them), this project seeks a solution to the problem of how to keep track of these numbers. This is a basic prototype of a shoe-mounted distance tracker […]
This is a creative cylindrical LED cube with proximity sensing by infrared led and photo-transistors. Interactive Cylindrical Cube includes: 8X8 royal blue LEDs, 12 infrared LEDs, 16 photo-transistors and all of them are bent & formed a cylindrical shape. Please see video below when this interactive cylindrical cube is used as flowerpot. Step 1: Bill […]
View this project on my website to see a circuit simulation and a video! Acoustic levitation is made possible through the fact that sound behaves as a wave. When two sound waves intersect each other, they can either constructively or destructively interfere with each other. (This is how noise-cancelling headphones work) This project uses an ultrasonic distance […]
Controlling a model train layout with a wired throttle and turnout controllers might be a good start for beginners but they pose a problem of non-portability. Also, the wireless controllers which come in the market can either control only some locomotives or are a bit too expensive. So, in this instructable, let’s learn how to […]
