Session 4: 7segment, useful application

Session 4: 7segment, useful application#

Review#

From previous sessions we have learned to:

  • Show a number on a 7segment

  • Work with multiple 7segments

Assignment#

For this session we are going show some trading data on 8 7segments. To do so, we need to take the following steps:

  • Connect 8 7segments to the microcontroller. (in simulation.)

  • At first, 4 7segments should show the name of the cryptocurrency.

    • For example, we can show BTC for Bitcoin.

  • second, 4 7segments should show the price of the cryptocurrency.

    • We want to show the price with 2 decimal points.

    • For example, for the price, we can show: 84.32.

  • Data are in 2 arrays:

    • names: contains the names of the cryptocurrencies

    • values: contains the prices of the cryptocurrencies

Valid charachters#

For all of us to be in the same page for the character presentation, we all use the presentation provided by this link

Example#

Data arrays:

String names[4] = {"BTC", "ETH", "DOGE", "ADA"};
float values[4] = {79.12, 19.02, 0.17, 0.73};

Expected Output:
