LED Matrix with Arduino
12V NE555 PWM Controller Under $3
Could someone help me ?, i need to construct a pure sine wave inverter with continuos current input and make the sine wave by arduino PWM, the power side of this project is easy ( just 4 transistors ) but i'm trying to find a programation of arduino, that can alternate the frequency and the width of the continuous wave quick enough to have the sine output. I will appreciate any help, because i have no idea the way i need to go in programation
