I have to control speed of a dc motor using arduino. Using tachometer i detect speed of the motor. However how will i decide the value for pwm.
Iam using arduino. What should i write inside function analogwrite();
Iam building this electromagnet for levitating a magnet below it using hall sensor as position sensor. Find the image for clearity.
However I have to find the transfer function of the whole system to apply PID on it, as the system is unstable inherently.
Electromagnet is wound around a long...
As i have read, in colpitts oscillator if A>C2/C1 the circuit is capable of oscillating at resonant frequency. but how does the change in value of inductor affect this stability criteria?

this was the frequency response of the circuit, and with the current circuit my...
when we give -Vee = gnd, how can the ic work as relaxation oscillator i.e. when capacitor discharges it can never go below ground level voltage and hence inverting side stays higher than non inverting side giving 0V at output instead of square wave.
Iam trying to design a magnetic Levitation System, with the help of solenoid, a magnet and PID controller. As iam using a hallsensor for sensing position of magnet and interfacing it with arduino, i dont get much range of voltage i.e. in arduino value varies from 350 to 500 with magnet and...
then can you plz explain how the comparator is setting up the two threshold levels and how to calculate those values? In circuits what i have learnt i never used a resonant circuit in non inverting terminal of opamp.
