Step 2What each part does
" Motion sensor: Detects motion from 20 feet away. When motion is sensed, a single bit output (electrical current) is created. This goes to the microcontroller chip.
" Microcontroller chip: When 5 volt message comes from the motion sensor, the microcontroller says turn on the motor for 5 seconds . My brother helped me with the code and we used his board to put the code on the microcontroller chip.
" Capacitor: This is between power and ground to smooth power to the microcontroller. The capacitor should be as close to the chip as possible.
" ET Tiny 25 chip: The chip holds the code. The code is the brains operating the motion sensor and motor based on electrical impulse.
" Voltage meter: The meter is used to measure how much DC voltage all the parts (motion sensor, motor, and resistor) take. If the voltage isn't correct, things burn up.
" Power brick: The power brick plugs into the wall and sends electricity to the unit (+ and charge).
" Solder: The solder is fusible metal which connects wires and keeps the current flowing. I used a soldering iron to melt the solder on the VHS board to remove the capacitor. I used solder to attach the wire needed to make the circuit. Always us goggles.
