So the winner has been announced this week - Sci Fi Your Pi: Winner Announced! and it was a well deserved win by the Meditech! by balearicdynamics. Even if i had more time I am not sure I would have been able to compete with this project or the other finalists there were some really amazing entries.
Seeing the announcement reminded me I said I would continue with the project despite the deadline having passed so here it is.. I have been working on this a little and have managed to get full direction of travel arrow circuit working.The system now takes the current position and lights an appropriate arrow(s) based on the direction to be traveled to the destination. in this below the arrows showing are South and East as I am North-West of the destination
Currently the destination is fixed so the next stage is to work on adding the destination selection circuits to make this possible. I have added a test circuit to the breadboards to test the idea and added the map travel LEDs as well so i can test that functionality too.
So far I have set up the circuit and it uses a pair of jumper wires rather than the planned wheels to select the destination and start locations. The LEDs that represent the correct rout light up indicating the route to be taken. The next step is to also use this input to set the destination for the direction of travel arrow.
I may have made a little more progress but it was my birthday so I was a little distracted by a new arrival - a Raspberry PI touchscreen (and flotilla case from Pimoroni.
I was also a little distracted by my Abobo robot project a little while back I added a seven segment display mouth and decided it used too many pins. i spent a while soldering in a shift register but hadn't got around to getting it running again. This week AgoBo got his smile back .
