At start, how to increase the starting voltage slowly... The starting voltage is 5V, and it is used to control the speed of dc motor, so at start the motor should start smoothly, increasing speed gradually... to limit the starting current... So I need to increase this control voltage 0 to 5V gradually at start.
I tried to make use of RC charging time constant, it works, but I need it only during start... if it remains through out the operation, then the speed response is very slow... because of capacitor charging and discharging...
The 5V is given to the microcontroller, which changes the ADC, which controls the speed of the motor...
Any help, much appreciated...
