need some help or guidance on programming a digispark to make led flash .

Hello community. I'm very new to this but this is always been calling me to work on and program little items .
My project is, I want to control 6- 5 watt led for strobe effect.i want it to have a button to activate the strobe effect . And if possible . I can setup different modes like different patterns of strobes . And if possible set off high pitch buzzer too. I know I'm asking for a lot but I've tried a to write a program . But it bricked my digispark. So I'm kinda doubting myself . If anyone can point me to the right direction it will be great . Thanks

A program can not brick anything. If you bricked your controller is is because you screwed up the hardware. High power LEDs need a constant current supply that you can switch with the small logic signal from a controller. Any other option is wrong, like using resistors or not using resistors at all.
