I want to control the Speed of 3 phase BLDC sensor less motor through IR2130 and Arduino UNO. need help from circuit to code.

Why that particular chip - its a lot more expensive than the FAN7388/FAN7888 or even the HIP4086
for instance?

The datasheet for the IR2130 refers to their application notes - that's the first port of call after
the typical connection diagram.

For sensorless BLDC control you are going to need to monitor phase voltages, either via
ADC channels or comparators, and probably do some noise filtering / signal conditioning
to cleanup all the interference spikes. There is somewhere an open-source ESC project,
I suggest finding it and studying their approach.
