Human: COVID-19 Tracker for At-a-glance : https://youtu.be/viHVAZqpwsI C - Cases R - Recovered D - Deaths LEDs fit snugly into holes designed for standard 5mm LEDs, with proper tolerance. If not, a quick blast of heat from a lighter on the standoffs allows the LED to fit. Here's a rough example of code that runs flashing LEDs: ```python import requests import json import RPi.GPIO as GPIO from time import sleep import threading CURRENT_DATA = {} ACTIVE_PINS = {"cases": 22, "recovered": 18, "deaths": 17} CHANGE_INDICATOR_ENABLE = False DATA_API_URL = "https://coronavirus-19-api.herokuapp.com/all" def get_data(): """This method obtains current data for COVID-19 from a reputable source. The return should be a JSON payload in the format of {"cases":n, "recovered":n, "deaths":n}. If this does not match, adjust the GPIO pin reference in ACTIVE_PINS to match the indicator lights based on the GPIO pin for each LED. :return: n/a - starts a thread to blink the GPIO pins.""" response = json.loads(requests.get(DATA_API_URL).text) print(response) if CURRENT_DATA != response: for key, value in response.items(): if key not in CURRENT_DATA.keys(): CURRENT_DATA[key] = value print('value was not found for %s, now added' % key) else: if response[key] != CURRENT_DATA[key]: print("%s is not matching" % key) threading.Thread(name=key, target=record_new_numbers, args=(key, value)).start() def record_new_numbers(key, value): increment_number = 0 print('adding %s, have %s need %s' % (key, CURRENT_DATA[key], value)) while CURRENT_DATA[key] < value: CURRENT_DATA[key] += 1 increment_number += 1 blink_n_times(ACTIVE_PINS[key], increment_number) def blink_n_times(gpio_number, blink_times): already_blunk = 0 # Long enable to indicate this is a new number increment. blink_gpio(gpio_number, delay=3) if CHANGE_INDICATOR_ENABLE else None while blink_times > already_blunk: already_blunk += 1 blink_gpio(gpio_number) def blink_gpio(number, delay=0.1, secondary_delay=0.1): GPIO.output(number, GPIO.HIGH) sleep(delay) GPIO.output(number, GPIO.LOW) sleep(secondary_delay) def setup_gpio(): GPIO.setmode(GPIO.BCM) for k, v in ACTIVE_PINS.items(): GPIO.setup(v, GPIO.OUT) GPIO.output(v, GPIO.HIGH) sleep(0.4) GPIO.output(v, GPIO.LOW) print("setup pin %s for %s" % (v, k)) if __name__ == '__main__': setup_gpio() print('Setup of GPIO pins complete') try: while True: get_data() sleep(30) except KeyboardInterrupt: GPIO.cleanup() ``` C - Cases R - Recovered D - Deaths
