Rotary Encoder As Joint Sensors without Interrupt Routine | DC Motor PID Control | Arduino | I2C

In this video I have shown how to use the rotary encoders without interrupt routines making them independent of micro controller. I have made a circuit which can send the encoder feedback to the controller via i2c. The ICs used in the circuit are PCF8575, D Flip-Flop, 74191, 4093, 4013.Us this circuit and Arduino PID library, I have controlled the speed and position of the DC motor which provides feedback from a magnetic encoder.

Great Keep sharing these type of videos

[@samverghese6311]

Great effort and a wonderful idea worth sharing....

Thank you :)

[@nishantsharma4465]

nice video , please mention some resources to learn ros in simple and interesting way

Hi Nishant,
Thanks for your comment.
I've written a blog to understand basics of ROS with examples. Refer the below link.

[@sdevane75]

could the 74191 be used to accuretly count a DC motor encoder pulses with Raspberry pi - as curremtly my raspberry cannot capture accurate counts?... thanks... help...

[@roboticsandroslearning8232]

Yes. But make sure to use de-bounce circuit also.

When new video?

[@roboticsandroslearning8232]

Thanks for your interest Igor Andrusyk. Sorry to keep you waiting but currently I am busy with other things. Will post a new video next month. Stay tuned.
