Hi everyone! This is my next project, Fidget Spinner RPM Counter or Arduino Tachometer with Hall-Effect Sensor. 1: Requirements Parts Required: Fidget Spinner neodyimium magnet Arduino Uno LED + resistor 220 Ohm Hall-Effect Sensor – a3144 resistor 10 k Wires Breadboard LCD 1602 2: Hall-Effect Sensor Using Hall-Effect Sensor we can measure the speed of […]
This device improves plant irrigation in urban environments. Powered by an Arduino 101, it uses on-board tools along with a few external sensors to calculate optimum conditions for watering plants in its own environment, and then waters the plant itself at the calculated time. It is based on the following concepts: Gravity and Pressure This […]
Now that the cheesy title has pulled you (Fitflix was taken and I didn’t want to be sued) I’ll tell you about the project, it uses a stationary exercise bike connected to an Arduino Nano to control the streaming of Netflix on a PC, I started this project hoping I could get it working on […]
So back when I first started working with micro controllers, Arduinos mainly the most annoying this ever was when i would follow someones tutorial for a project and they would use the Arduino uno, I would be using the Arduino micro or something, i would spend like an hour wiring it up following the instructions […]
Story When you measure distance between two point general way is to use a ruler. But you can use a lot of other ways: by laser, map, foot or walking meter. The walking meter is very useful when you are measuring curved (not straight) distance. But it might be very tired because you should walk […]
Story When it comes to portable electronics, one of the most important features is how to maximize the battery life. The ATmega328P, used on popular boards like the SparkFun RedBoard, Arduino Uno, and Pro Mini are actually quite power hungry. The RedBoard and Arduino Uno, draw around 15mA minimum, which doesn’t sound like much but […]
Story I have been working out ways to make a minimal Arduino to fit in the smallest space possible, and limit the power consumption of the microcontroller. (You can go through this project for more info about reducing power consumption at: Reducing Arduino Power Consumption). You can assume this one is an extended version of […]
Story A Continuation of One Button Restart of a Stalled Raspberry Pi In a recent article, I showed how an Arduino Pro Micro can be utilized to send characters to the serial console of the Raspberry Pi Zero W. The Pro Micro was chosen because it is small, inexpensive, and easily acquired plus the integrated […]
Story In the future there is a bar where all the dead punk rockers hang out. They are each given a MiFare classic card programmed with their name and 666 credits. This is the device the bartender uses to keep track of their tab. This project uses an atmega168 to control a pn532 breakout board […]
Story Imagine you could administer remotely your water utility service in real time, turning on or off your water services according to your usage patterns or needs, and not just letting the water flow in all the time, you could prevent taps for leaking a single drop per one faucet per one home leaking wastes […]
