Abstract:
This project report discusses the design and construction of an audio speedometer system for
motorcyclists. The system reads and produces an audio speed. The device has a control button
which prompts speed speech on press and displays it alphanumerically on a 16x2 LCD in real time.
The system prompts rider to enter their likely maximum speed and if this is exceeded on riding,
the rider is alerted by the audio sound. The system is based on an 8-bit RISC AVR microcontroller, the atmega328P-PU. Speed computations are as a result of a hall-effect sensor in close proximity with a magnetic material. The system aims to reduce safety hazards from having to tilt or move one’s head when trying to view speed on a motorcycle speedometer, which is usually mounted down by the handlebars.
