This tutorial explains how to discover i2c devices such as the SSD1306 and GY-21P.

From a high level overview, i2c allows to create a signal line of communication between multiple devices without having to physically address them. This is extremely useful for projects that might not have many ports on the device, but need to manage multiple peripherals.

While the gy-21p is similar to the gy-68, it has a different look that can be easier to identify. Having a fritzing part to make it easier to work with was a must have so I made on.

This tutorial explains how to use a GY-521 driven by an esp32-c3! This is an I2C board with a combined Gyroscope and Accelerometer. It has the ability to get:

  • X, Y and Z acceleration
  • X, Y, Z gyroscope
  • Temperature sensor

Working with the esp32-s2 has been super interesting! Like many boards produced by ai-thinker, this one didn't have a great fritzing model so I adapted one of the existing esp32-s2 dev module boards to look more like the one produced by ai-thinker.

I have played around with the esp32-c3-32s for a while, and it doesn't have a decent fritzing board. So I have been forced to make some less than optimal images showing a simple project on a breadboard.

There is an overhead to being able to edit existing boards. I have yet to understand how boards are created from scratch, because they look so accurate!

Over the past year, I have been using the esp32 as my go-to Arduino at heart micro-controller. It has Bluetooth and Wi-Fi, it’s power-efficient, and it costs less than $5. In my quest to find something more robust, I found the esp32-c3.
