Description
For this assignment, Jin and I collaborated to design a garden weather chime that 'chimes' nursery rhymes based on the weather. If the weather is sunny, it chimes a happy "The Mulberry Bush". When the weather is windy or it is raining, it chimes "London Bridge" and "Rain, Rain go away" respectively. On a cloudy day, it chimes "I hear thunder." The chime also has built-in LEDs that flash as it chimes. In the night, it dosen't sing anymore but continues flashing lights. The chime is also painted to camouflage it in the garden foliage.
For the circuit, we used an FSR and a Photocell to detect the 'light' of the day and the 'pressure' (esp. for windy and rainy days) and play the appropriate song. We also used LEDs for the flashing lights.
