    I have 40 led's connected to each pin of MCU. M
    Now MCU can't drive each led. So waht I am thinking of right now is to drive 2n7002 gate with each pin which will drive the led. In this I have to connect 40 2n7002.

    Any other better solution for this.

    1. MCU is 3.3V powered.
    2. Have to individually control each led.
