Austin Shaf 2010 – Atmega8 16PU Student Soaker – The ultimate school prank. A user will have the capability to spray students walking throught the halls with water without them knowing the source of the water. The student soaker will be placed above a ceiling board above the school’s hallway. The device will be connected to a pump that sprays water. The user activates the pump using a one channel transmitter. A receiver on the module’s end outputs a analog voltage that the ATmega8 reads. The speed of the pump is based on the analog voltage.
