Bitcoin value ticker

Posted by Voshicage

This is the second (and final) iteration of my office bitcoin price ticker. The concept is simple. Every ten minutes the current price and trading volume for bitcoin is pulled from the Interwebs, parsed and then displayed on a wide led matrix. Here is my parts list: 1 x Arduino Yun (I don't think they make this anymore, but I had it already. Bitcoin is the world’s first cryptocurrency and blockchain. Bitcoin was first described in a white paper published by Satoshi Nakamoto in October, Nakamoto is believed to be a pseudonym for the individual or group responsible for Bitcoin as there is no record of a computer scientist by this name prior to the launch of Bitcoin in Find the latest Bitcoin USD (BTC-USD) stock quote, history, news and other vital information to help you with your stock trading and investing.

In , a U. Federal judge concluded in the Coinflip, Inc. The supply schedule of bitcoin is deflationary. This schedule — embedded in the Bitcoin protocol — dictates that every time a miner successfully writes a new block to the blockchain i. The block reward is how all new bitcoin are issued or minted, and how all bitcoin in circulation have come into existence.

On November 25, , the first halvening occured, halving the block reward from 50 to 25 bitcoin. On July 10, , the second halvening occured, halving the block reward from 25 to The third halvening is expected to happen in May, and will reduce the block reward from The block reward will continue to undergo halvings until it reaches 0.

This is estimated to happen sometime in the year At this point in time, there will be a total of 21 million bitcoin in circulation. HODL is a slang in the crypto space that refers to the act of buying and holding bitcoin. HODL has become a prominent internet meme and rallying cry for the Bitcoin community, especially during times of high volatility and large price declines.

The basic principle behind HODLing is to take a long term buy and hold view towards bitcoin as opposed to a short-term one that involves trading in and out of bitcoin on a daily, weekly, or monthly basis.

HODLING avoids having to correctly time trades with the market and react to price volatility, which can result in buying high or selling low. It does, however, require strong conviction and resolve during market downturns.

This content is provided for information purposes only. Bitcoin is a digital currency, which allows transactions to be made without the interference of a central authority. The cryptocurrency system is a peer-to-peer open-source software, meaning computers are part of a mining process for coins. Bitcoin was designed and created by an anonymous programmer, or possibly group of programmers, by the name of Satoshi Nakamoto.

There are various places to buy bitcoin in exchanges for another currency, with international exchangess available as well as local. Popular international Bitcoin exchangess include Bitsquare, Coinbase, and Kraken.

Bitcoin can be purchased through a digital marketplace, through which you can fund your account with your currency of choice, and place an order on the open market. Bank transfers are the most popular mode of payment. The use and trade of Bitcoin is legal in the majority of countries in the world, however, because it is a deregulated marketplace, governments are concerned about its potential threat as a tool for money laundering.

Although mining and exchanging are questionable in terms of legality, it is known to be legal for users who exchanges bitcoins for goods and services. Using a blockchain ensures security and manages digital relationships as part of a system of record. A distributed ledger is a database, digitally recording transaction information using cryptography, making it secure and unforgeable. There are several differences between a blockchain and a database, including the level of control.

I used an Uno to test, and a YUN on the final board. The pins are different on the YUN. Below is the program I came up with to display a string on the large matrix. There is probably a more elegant way to make all the matrixes work together, but this made sense to me. What I am doing is setting an offset for each 16x8 matrix based on their location in the 96x8 matrix. So each matrix will be displaying the string all the time, but as the string starts on the right side of the large matrix, the smaller matrixes are offset so that they are displaying the string at a position "off screen".

Eventually, they will work their way up to the start of the string. The position is updated each time through the loop via updateTicker. I used the comparison of milliseconds to trigger the updates since I will want to be doing other stuff between updates such as pulling the updated bitcoin prices, adjusting brightness, etc.

If I used a wait, the microprocessor would not be able to go do "other stuff. I didn't want to spend a lot of money on a housing, so I just cut an oak board to approx 2 foot long, routed the edges to make them round.

I then used a straight router bit to make an area in the back of the board to accommodate parts and wires, and to thin the board so the pots and switch could reach through. This works fine, but you have to go slow with the router. To mount the matrix to the board, I first placed the board with the posts on the top of the board and marked the post locations. Let it dry for 24 hours. I updated the Linux side of the Yun and then connected to my network.

That way it could fetch data for the Arduino side of the board. Below is my code. I struggled with several aspects of the program and bounced around the internet trying to find clues to making it work. Frankly, there is probably some code in here that is from another programmer that I forgot to acknowledge or make a comment about the source.

That can be a problem with doing a project over a couple of months with just a few minutes here and there. Great instructable and easy to follow!
