So it is actually possible to control brightness of the led light by using pwm method which is just connecting the pwm output pin from the microcontroller straight to the vcc and gnd of the led light without using any external circuit? Signals are then programmed in the microcontoller itself to control the current/voltage.
Thanks for the info. But if there's such a risk, is there any circuit recommendations or any other simple method that i can put into use to interface the led with microcontroller? Cause i'm actually quite new to the electronic stuffs and im required to come out with a prototype within a short period of time. So I probably need a straight-forward and simple design to help me implement this project.
The question was how to do it with a microcontroller. That means PWM
