Google is not giving it's API for turn by turn navigation.To one of my university project I'm arduino connected hand glove to get call notification,health monitoring and most importantly navigation.
I made all the call notification,heath monitoring parts but I can't figure it out how to notify to user when a turn come to "Left" Indicate using a LED bulb.
I have an idea like this: If I can get google maps navigation voice output as input to make a strings like "Left" or "Right"I can Indicate using that strings.
Currently I don't have codes on this.
p.s : Here maps and other maps are not using only google maps.
