We all have at one point or the other user our smartphones to navigate to a place. This device does exactly this, accepts it’s made from scratch. Also it can be used when you want to follow a certain specified path from another user who have already used your device. This device could be used for hide-and-seek, or some sort of exciting maze game and hence can promote children to play outside. The data from the compass and GPS are taken into the microcontroller, and is then processed to determine where the user is in space, and which direction they are facing.
Based on these data, the device then generates feedback on whether or not they are getting closer to the right place, or are even facing the right direction. The GPS module gives serial data and can be accessed using AT commands which are also used for GSM communication. An Atmega128p is used to interface the compass, lights, switches and the GPS module. A different project which could also be modified to work indoors. Also, more feedback techniques such as haptic feedback can be added instead of light based feedback.
