The anemometer is a device capable of measuring the wind speed and its direction. Using a Hall Effect sensor we will be able to count how many rotations the cups give in a period of time. The intensity of the wind is proportional to the speed of rotation of the axis. With some simple ...
By combining inputs and outputs with some basic logic commands, you can make things happen automatically. Such as having alaser trigger wireto detect if anyone walks through a door, and making a ding-dong sound to alert a store clerk that a customer just entered. Check outWhat Is Arduino ...
Arduino and Raspberry Pi Sensor Projects for the Evil Genius by Robert Chin. McGraw Hill, 2017. Several of the projects in this book involve hooking up reed switches to Arduinos and Pis (there are complete instructions for a reed-switch door buzzer alarm). MAKE: Electronics by Charles Platt...
A complete guide onHow to use the built-in hall effect sensor of ESP32 It also has one hall sensor which is used to detect the magnetic field. Whenever you please this development board in the magnetic field, ESP32 generates a small voltage which can be measured with any pin. I will p...
Arduino Step-by-Step Projects » Build 25 Arduino projects with our course, even with no prior experience! What to Read Next… ESP32 Built-In Hall Effect Sensor with Arduino IDE and MicroPython ESP32/ESP8266: Run Daily Task at Specific Time (Arduino IDE) ESP32: K-Type Thermocouple wi...
with a monitor to display the measured value of current. There are many ways to measure AC current like Inductive Sensor, Hall effect sensor, etc. but we are using the current transformer in this project. Using this project, we will be able to measure AC current of range 0.1Amp – 5 ...
It has a built-inHall-Effect sensorthat can detect changes in the direction ofmagnetic field. So, we just have to attach a magnet to the output shaft of the motor and position it close the microchip at a distance from 0.5 to 3mm. ...
I'm going to show you how to emulate an Xbox controller with an Arduino, using a USB capable microcontroller and the ArduinoXInput library.
Next, we just have to open the jaws and clamp around the wire we want to measure the current. As an example, I’m measuring the current draw of some LED strips. We can see the current passing through that wire is around 3.2 amps. ...
Make: Sensors: A Hands-On Primer for Monitoring the Real World with Arduino and Raspberry Pi by Tero Karvinen, Kimmo Karvinen, and Ville Valtokari. Maker Media, 2014. Building on the book above, you'll discover quite a bit more about accelerometers in this title, especially "Chapter 8: ...
