My controller outputs square waveforms in 5 volts PWM SIGNAL.
I want to change the waveforms into current waveforms with some circuits.
The final output could be 10 milliampere square current waveforms, and the amplitudes will not be changed with different loads. Can any one suggest me a circuit for this?
What is your arduino board?
You first of all take the PWM signal and apply a low pass filter to remove the PWM, and leave you with a pure voltage output.
Voltage and current are the best of friends, and all a current is, is a voltage being applied through a resistor. So why do you want a current signal? What is this giving you?
A PWM signal is an OFF-ON waveform with the on time and the off times being varied. You are asking for a current being turned on and off for varying times. Why?
You say the voltage is 5V, what will the current be? Amps, milliamps, microamps?
