I am using pic 16f877a for measuring rpm of a motor, it uses an this hall effect sensor link. Problem I am having that this seller is not providing any documentation for this sensor, it has an analog pin as well as an digital pin which is one confusion.
If sensor is giving digital o/p at every time it comes near a magnet then how will I measure its rpm. I am using Mikro C for coding and I also have other buttons as inputs so if I loop for long period then I might miss the button press.
First of all, i would like to thank you for such a worthy platform to share ideas. i wish electrosome to be a big success.on my side, i have decided to buy the required electronic components from electrosome from now on.
As far as speed control of dc motor using pwm module of pic16f877a on ur site is working good. i could control speed of a 5v motor. and actually i need to control the 24v dc motor, is uln2803 driver and a 24v dc relay with the 24v supply is sufficient or do v have to use triac application in it???
