Abstract
The most common and significant of all visual tools is the boards. A classroom without
a whiteboard is impossible to envision. It is crucial in ensuring the effectiveness of the
educational process.A student’s hair may stand on end from the scratching of chalk against
the traditional boards. Dry-erase markers are quiet and gentle, but they can produce
vapors in the classroom and contribute to indoor pollution. Annotate project not only
get rid off the clutter of chalk and markers that may clog up a traditional classroom,
but it also reduces the amount of paper necessary to teach. Instead than utilizing paper
handouts.
Annotate is built and created by combining several techniques, such as processing the
images required to track the pen’s movements and transferring them via WiFi to the
microcontroller, which then transfers the set of processed and extracted points from the
images to a special software via USB, which then draws and displays them on the board. It
supports multi-threading, which allows it to do numerous tasks at once, such as receiving
signals from the pen and the keypad, processing them, and sending the processed signals
to the software.
