Fidget Spinner Tachometer, Revolution and Time Counter using Arduino and Hall effect sensor

Рет қаралды 27,713

6 жыл бұрын

Another simple weekend project ...
Parts:
- Arduino Pro Mini
- I2C OLED display
- A3144 Hall effect sensor
- Neodymium magnet for spinner
Features:
- 4 values are displayed: rotation counter, RPM, max RPM and time of rotation
- results are kept on the display until new rotation starts
- interrupt is used for accurate measurement (pin 2, interrupt 0)
- my own old OLED lib is used with companion of fast software I2C library
- any pins can be used for SDA and SCL
- however regular hardware I2C can be used too, just set "USEHW 1"
Source code:

good work! Have you tested A3144 with high-speed rotating object (e.g. 200 RPM) constantly for a minute ? just curious about how accurate it is . I'm looking for the most appropriate one for my robotic car project, thanks

hi, can you help me please. i want know the units that use this Sensor, when i measure the magnetic field i see that when the sensor unaffectedly is 512 i use the sensor hall 94E but i don't understand the units that use and how i can messure the magnetic field in tesla

Thanks for the video, it is a great starting point for my project. May I know how I may refresh the Max RPM whenever a new rotation start?

@wilbertyuen4116 3 жыл бұрын

Can anyone help to answer why the time sometimes jump when the RPM starts at high speed?

Hi, I have a problem when I detect the magnet I have to rotate it and bring it close again that the sensor can detect the other side and after that I can detect the original side of the magnet. So I need to constantly rotate the magnet for the sersor to be able to detect it. Can you please help me?

this is a very good project... except for the novice user, i cant install the libraries and therefore cannot run your code... just a little more effort would have made this a great tutorial... thanks for the time tho..

Zrobiłłem sobie kiedyś dongla IR do telefonu (ledy podłączone przeciwsobnie L-R do jacka). Użyłem go niedawno do pomiaru prędkości spinnera, bo LED-y działają jako fotodiody. Do tego latarka oraz Audacity i mamy pomiar .. Bez magnesów, które sprawiają problem z wyważeniem :P

@cbm80amiga 6 жыл бұрын

Ale cos pewnie musisz nakleic, bo inaczej bedzie malo dokladnie. Widzialem wiele optycznych licznikow, ale zwykle bylo zliczane przecinanie wiazki swiatla lub lasera. W rezultacie wynik byl 3 albo nawet 6x za wysoki. Dodatkowo problem ze swiatlem jesli uzyje sie zwklych diod a nie IR. Tutaj przynajmniej wiem, ze zliczane jest dokladnie to co chce, czyli "spotkanie" z magnesem. No i pradu mniej ciagnie :) Jak mi dojda w koncu TCRT5000 to sprawdze jak to zadziala.

Google this lib and download it. Or use HW I2C mode via proper define in the code.
