Fun project = Bravo. Suggestion = I am rather confident that you do not need the relays, at all. You should be able to drive the MOSFET gates directly from the transistor outputs... I think. And, I think that you should be able to drive the transistor bases directly from the ATtiny85 pins. Depending on what the current requirements are to drive the coils (and a little more for the LEDs, themselves,) you might be able to use a small 2N7000 MOSFET. So, the layout would be this... ATtiny85 output pin to base of transistor. Transistor output to gate of MOSFET. Output of MOSFET to coil. Now, that I think about it, you may not need the transistors, either. Maybe you can drive the gates of the MOSFETs directly. You would need to read the data sheets for the ATtiny85 output abilities and the MOSFET gate requirements. HTH.

Thanks for the suggestion🙏😊. But I think the high frequency reverse from the coil can damage the microcontroller. So I used the relay for Isolate the microcontroller from the coil circuit. I can also use optocoupler for better isolation.

How about an optocoupler? They have isolation and a transistor. There are some hardier/stronger models. You have me thinking...

We can't use the MOSFET Gate pin directly, because the gate pin is connected to the feedback winding of the coil so that that mosfet can generate frequency by switching on/off. The relay is only providing current to each coil circuit one by one. And also it can isolate the microcontroller from the coil circuit.

@@CreativeGoutam Thank you for continuing to explain this to me. "We can't use the MOSFET Gate pin directly, because the gate pin is connected to the feedback winding of the coil so that that mosfet can generate frequency by switching on/off." I am having trouble conceptualizing this part. A schematic would help. Maybe include them in your future videos. I didn't miss it, did I?
