Although the circuits seem simple, a detailed project is controlled from the parallel port of the computer. The circuit built on the 74LS04 is isolated with 4n26 opto couplers and powered by IRF1010E Mosfets. The parallel port is the port that allows to manipulate the stepper motors in any desired variable such as speed, position…
PIC16F84 4 MHz crystal is connected 100 Hz PWM output produces a pulse width of 10 separate levels are adjusted these values asm software vary from circuit only engine that not all GUS control applications can be used on a frequency of 50 Hz is set inverters driven circuit two buttons have their power levels…
CCS PCM compiler pic16f876 microcontroller circuit prepared with software installed on the PIC hex output FETs are driven IRL1004 MOSFET PWM frequency of 10 kHz with the engine. Prepared with eagle pcb circuit and printed circuit board file source software. I tried several ready made PWM speed control circuits. Of the few I tried, there…
