EEPROM example for PIC1814K50

Shane Ormonde10 years ago8 months ago01 mins

For a previous project involving stepper motors, I wanted the microcontroller to remember exactly where the stepper motor was even after power loss. There wasn’t enough time to attempt it then, so I thought I’d try something similar now.

2d mapping using a webcam and a laser

Shane Ormonde10 years ago8 months ago211 mins

Following on from my previous blog post using a webcam and a laser as a rangefinder, it’s now mounted on a cheap 3 euro stepper motor and used to make a 2d map of the surroundings. As you can see from the video the results are not great, I think with a bit more work…

Sumobot build, the progress so far

Shane Ormonde10 years ago41 mins

It’s a speedy piece of kit by the looks of it! At the moment the code written just keeps it from falling off the table. When this video was shot there were little white specks on the table causing the robot to turn around even when it was on black.

Sending analog values over serial using a PIC 18F14K50

Shane Ormonde10 years ago8 months ago01 mins

There’s a Robosumo competition coming up. The microcontroller chosen for the job was the PIC 18F14k50. The sensors being used are Sharp infrared rangefinder (to locate the opposing robot), and IR colour detecting sensors (to detect when the robot has reached the edge of the ring). All of these sensors give out a voltage somewhere…

    Not unnecessarily complicated enough :D

    Why don’t you just use GPS with 2 cm accuracy which is achievable with RTKLib?

    From where i can read out more about it. Do you have any suggestive readings?

    You would also need fast Fourier transform to find out waves frequently to use it as reference point to give…

    You would need wind sensor real-time data. You would need to tilt compensate wind data from real time IMU data.…
