Contact person: Update APIs and Data Display on ESP8266 OLED Project - Arduino

Phone:Show

Email:Show

Location: BCN Ciudad, Spain

Budget: Recommended by industry experts

Time to start: As soon as possible

Project description:
"I have an Arduino-based project running on ESP8266 boards with OLED displays (SSD1306 and SSH1106). The framework and firmware are already developed and editable through a web-server interface. The project fetches and displays live data from various APIs in ticker/scrolling text and chart modes.

I am looking for a programmer to update the APIs and ensure the data is displayed properly on both OLED screen sizes.

Current Setup:

Boards: ESP8266

Displays: SSD1306 and SSH1106 (OLED)

Firmware: Arduino-based, editable from a web-server

Functions already in place: framework for API calls, display logic, ticker/chart modes

APIs / Data Sources to Update:

1. Selected cryptocurrency values (stock ticker style: scrolling text or chart mode)

2. CO₂ price ticker

3. Top billionaires list

4. Selected military stock ticker

5. Selected Worldometer info (population, health, etc.)

What I Need:

Update the above APIs in the existing framework

Ensure the data is fetched reliably and displayed correctly on both OLED screen types

Maintain smooth scrolling ticker and chart display modes

Nice to Have (Optional):

Guidance on how I can later update or change APIs myself

Deliverables:

Working firmware with updated API integration

Documentation (short notes) on how to modify/update APIs in the future

Notes:

The project is not from scratch, it’s mainly updating APIs and making sure everything displays correctly.

Looking for someone efficient, reliable, and not overly expensive since the framework is already in place." (client-provided description)
