Hey everyone
I need someones help, and i'm very thankful for all help. I have searched the net for hours without finding out the answer to my question.
I have a simple diagram. I have a LED light (6W, 320mA), a driver, and a Audrino board.
The driver gives power to the LED light, between the driver and the LED is an unknown transistorm and from the transistors base it goes to the PWM output (5V, 40mA) of the Audrino board.
What i need help for is figuring out the circut between these 3 compenents. The driver, LED and audrino. I dont know what transistor i shuld use and what kind of resistor.
The idea is that the Audrino board is dimming the LED light with PWM thro the transistor.
Can anyone help me with this prosject?
And sorry about my bad english =P
