The official mixer for Lego WeDo 1.0 Instructions are straight forward, use the motor mixers for the motor power and the light mixers for the lights. Turn both on for light (the light slider with the highest value will set the light power) and one slider up but one slider on 0 will make the lights flash.
Music is test sound (Kool & the gang - Celebration) To change music: 1. Add music to the 'Play' sprite (the play button) 2. Change the 'Play sound until done' block under the 'When sprite clicked' block to the song you added. Enjoy!!!
