Question 3 Ved R LED RX63N מלח Figure 03. LED interface Change the LEDs intensity by changing the duty cycle. We want to use Timer TPU6 and PWM mode 1. 1. If Ydd is 3.3V and the LED has a voltage drop of 1.3V Calculate the resistor R required to have a current of 15mA. (5 marks) 2. Explain what would be the reason to use a transistor to drive the LED?
