    Hi Everybody The project i have is a controlling 5 leds from a ESP8266 using the pwm. I had a prototype pcb milled out by a friend with a LDR circuit to the A/DC IN pin, a motion sensor input, & 5 x Mosfets to pwm the leds WRGBW. I can program the esp and had a play with MCU/Lua. but due to work and family i don't have enough hours to get it

    ...the phases and DC input. The software will regulate a 3 phase output up to 500 hz(programmable value). The amplitude of the 500hz wave will be variable based on a 20 khz pwm(programmable value) signal applied to each gate. This is like trapezoidal control. Later we will implement sinusoidal, or maybe you have knowledge of this. Current will be

    I need for the PIC18F1220 to read an analogue value from a sensor and send a PWM signal to a servo motor(direction) and another PWM to the motor to control the speed. I will provide a working code with is using a normal bang-bang controller method, however, I prefer to have a code with a simple PI controller. I understand basic coding however for my
