I'm working on an RGB LED project for which I have designed a driver (Original Design). Everything seems to be in place but there is some problem that is causing the Drains/Output to be always High even though I've not connected the Gates of transistors with any input source. I'm planning to use it on arduino and PWM signals to be fed in from the Digital Pins.
The Transistors (Q1, Q2, Q3) are IRF540N and Resistance (R1, R2, R3) are 22K Ohms. Ground of driver will be connected to Ground of arduino and +ve of Power source (J2). Please suggest if there is an issue in the schematic below.
