    Hello, I am developing a bump and turn Buggy. My manager wants Back lights (Red LED’s), Front Lights (White LED’s) and a Buzzer. I intend to drive a 3v Buzzer active low – it seems to work. Will a pair of standard 5mm RED LED’s be OK in Parallel off one output for back lights? Likewise two 5mm White LED’s for Front? Or should I get 5V versions or put limiting resistors in?

    Yep – the Crumble outputs can drive plain LEDs
