This DIY Parking Sonsor using Arduino, ultrasonic range finder and some of components

The last time I was home visiting my parents I noticed bumper imprints caused by my mother suburban on the stairs leading up from the garage. Their garage it turns out is just barely long enough to fit their gigantic vehicles. So I decided it would be nice to have some visual cue for parking. Out came the arduino and a sonar range finder from Radio Shack.

The basic concept of the Keyglove is to generate input signals by touching unique combinations of conductive sensors together. These sensors are mounted on the fingers and palm of the glove in strategic places to allow for the greatest possible number of combinations.The glove also has an accelerometer on the back, which will be used (where applicable) to control mouse movements.[more]
This project uses a device called a differential pressure transducer to measure the water pressure at the bottom of the tank, and from that to calculate how full the tank is. Water pressure increases by about 9.8067kPa per meter of depth so a full tank 2m tall will have a pressure at the bottom of about 19.6134kPa above ambient atmospheric pressure.[more]
This Arduino based project is housed in an old cigar box found in a thrift store. The Fortune Teller flashes it’s lights and then will give you a fortune and a lucky number after turning it on. Just press the button for another fortune. Currently there are about 15 different fortunes. [more]
This project combines a battery-operated doorbell, antique phone, Arduino, and subscriber line interface circuit (SLIC) to make a wireless doorbell. Readers are taken through basic phone restoration, creation of a custom doorbell button transmitter, modification of the receiver, workings of the SLIC, and description of the Arduino code.[more]
