Hall effect sensor LM393 cycle computer implementation

Customer:

I have a question about the Hall effect sensor with LM393 that I purchased. I want to build a cycle computer to measure speed and distance travelled. I haven’t programmed before and tried searching online but couldn’t find code that would work for this. Do you have any code for a speedometer that works with a hall effect sensor that you could share? Or is this explained in a tutorial that I might have missed?

Original message (Croatian)

Imao bih jedno pitanje ako može. Kupio sam Vaš Hall efect senzor sa LM393. Htjeo bih si napraviti km/h sa brojačem pređenih metara. Pošto nisam vičan to sam isprogramirat tražio sam po netu ali nisam uspio naći kod koji će mi to omogućiti. Dali možda Vi imate kod za kilometar sat koji radi sa hall efect sensorom da mi možete poslati?

Ili to možda imate u nekom tutorijalu objašnjeno a da sam ga slučajno preskočio.

Puno hvala.

Soldered Support:

We don’t have documentation or code for that specifically, but searching for “Arduino cycle computer” online will show many relevant projects. One example: Arduino Bike Speedometer : 16 Steps (with Pictures) - Instructables The approach depends on your wheel diameter. Essentially, you measure the time between two detections from the hall effect sensor and calculate the speed from that.

nažalost nemamo to negdje objašnjeno, niti kod za navedeno, ali ako guglate “Arduino cycle computer”, dobivate dosta projekata na navedenu temu. Primjer: Arduino Bike Speedometer : 16 Steps (with Pictures) - Instructables
Sve ovisi na kraju o promjeru kotača Vašeg bicikla, a jednostavno mjerite vrijeme između dvije detektcije putem hall effect senzora i računate brzinu.
