How to Build a Bitcoin Clock258

A Bitcoin clock is a clock that displays the current price of Bitcoin in real-time. It is a great way to stay up-to-date on the latest Bitcoin price action and can be a great conversation starter. In this article, we will show you how to build a Bitcoin clock using a Raspberry Pi and a few other simple components.

Materials* Raspberry Pi 3 or 4
* 7-segment LED display
* Driver board for 7-segment LED display
* Breadboard
* Jumper wires
* Power supply
* Internet connection

Instructions1. Connect the 7-segment LED display to the driver board. The driver board will typically have four pins: VCC, GND, DIN, and CLK. VCC should be connected to the 5V rail on the Raspberry Pi, GND should be connected to the ground rail, DIN should be connected to GPIO 18, and CLK should be connected to GPIO 19.
2. Connect the driver board to the Raspberry Pi. The driver board will typically have a 40-pin header that plugs into the GPIO header on the Raspberry Pi.
3. Install the necessary software. You will need to install the following software on your Raspberry Pi:
* Python 3
* Adafruit_LED_Backpack library
* requests library
You can install these packages using the following commands:
```
sudo apt-get update
sudo apt-get install python3
sudo apt-get install python3-pip
sudo pip3 install Adafruit_LED_Backpack
sudo pip3 install requests
```
4. Create a Python script to display the Bitcoin price. The following Python script will display the current Bitcoin price on the 7-segment LED display:
```
import time
import requests
from Adafruit_LED_Backpack import SevenSegment
# Create a SevenSegment object.
segment = (address=0x70)
# Set the brightness of the display.
segment.set_brightness(0.5)
# Get the current Bitcoin price.
url = "/v2/prices/spot?currency=USD"
response = (url)
data = ()
price = data["data"]["amount"]
# Display the Bitcoin price on the 7-segment LED display.
segment.print_number_str(price)
# Wait 1 second and then repeat.
(1)
```
5. Run the Python script. You can run the Python script by typing the following command into the terminal:
```
python3
```
Your Bitcoin clock is now complete! You can now sit back and watch the Bitcoin price change in real-time.
