For this project, we evaluated a few options and settled DevKit 1.0 Development Board for its compactness and our familiarity with using an OLED display with it in past projects OLED display with it in past projects! The SoC comes in a variety of modules, breakouts, and development boards.

we love it! It's the most convenient, inexpensive way to have a microcontroller running code while connected to a Wi-Fi network. What can we say about the ESP8266 that hasn't been said about the wheel, sliced bread, or the iPhone. Not only are these displays small (and bright!), but they're very easy to control over i2c merely having to connect 4 wires to our microcontroller or single-board computer: 2 for power and ground, and 2 for the data and clock lines. Given our main goal of having a device with a small form factor that could sit on our desks, the first choice was to use a 0.96" OLED screen to display the price data. To build a price tracker for cryptocurrency we simply needed two pieces of hardware: an internet-capable microcontroller to gather the data, and a screen to display it, we tried to find the best solution considering ease of use and cost. In terms of what's required, we challenged ourselves to use the minimum number of parts, and require no special tools/skills such as soldering. The main goal is to have a dedicated, inexpensive, device that would help us avoid repeatedly checking websites, apps, email, writing scripts, etc., in order to monitor the ups and downs of coin prices. Not to mention that building the device is a great excuse to work on a ESP8266-powered, internet-connected, DIY electronics project for any Maker out there! (bro/sis, do you even IoT?)
With the latest craze in the world of cryptocurrency and, as coin hodlers ourselves, we wanted to have a tiny desktop display cycling through the current prices of different coins.Īlthough we can certainly find the same information using apps and websites (for free!), we discovered that having a dedicated device on our desks displaying the data constantly minimized the time we spent on tracking it.
