\"BitCoinSensor<\/a><\/p>\n

This is an IoT solution for monitoring the price of Bitcoin with Visual and Auditory cues pertaining to the volatility of the the CoinDesk exchange over a given time interval. <\/p>\n

This project obtains the latest BTC price from CoinDesk every 30s and displays the value with a Green or Red background on the LCD based on whether the price has increased or decreased respectively since the last request.<\/p>\n

Volatility is a measure of how much the price of a financial asset varies over time. This project also allows you to set an auditory alarm which sounds when the volatility index is exceeded. <\/p>\n

The Volatility Index is computed using the exponential moving average formula:<\/p>\n

accumulator = (alpha * currentNumericRate) + (1.0 – alpha) * accumulator
\nvolatilityIndex = (currentNumericRate \/ accumulator) – 1<\/p>\n

Note that the volatility Index is directional, thus if it is negative the volatility is moving the price downward and vice versa if positive. <\/p>\n

The idea behind this project is to alert a potential investor of breakneck swings in the price of BTC. This could be very important given that the BTC exchange is open 24\/7. Thus, a savvy investor could potentially save themselves from a heavy loss if they were alerted to say a 5% negative volatility Index swing that were to occur while the investor is sleeping. Likewise, one could be alerted of a peak selling opportunity should the volatility Index report a rise. <\/p>\n
