What is WipperSnapper
WipperSnapper is a firmware designed to turn any WiFi-capable board into an Internet-of-Things device without programming a single line of code. WipperSnapper connects to Adafruit IO, a web platform designed (by Adafruit!) to display, respond, and interact with your project's data.
Simply load the WipperSnapper firmware onto your board, add credentials, and plug it into power. Your board will automatically register itself with your Adafruit IO account.
From there, you can add components to your board such as buttons, switches, potentiometers, sensors, and more! Components are dynamically added to hardware, so you can immediately start interacting, logging, and streaming the data your projects produce without writing code.
If you've never used WipperSnapper, click below to read through the quick start guide before continuing.
First, wire up an INA228 to your board exactly as follows. You can use a Stemma QT cable to make wiring the boards together easier if you prefer, but here is an example of the INA228 wired to an Adafruit ESP32 Feather V2 using I2C via Dupont Jumper Wires mounted in one of our prototyping breadboards:
-
Board 5V to breakout VIN (red wire)
-
Board GND to breakout GND (black wire)
-
Board SCL to breakout SCL (yellow wire)
- Board SDA to breakout SDA (blue wire)
- Breakout Vin- to load's highest potential (red/white banded wire)
- Breakout VBus to breakout Vin+ (pink wire)
- Breakout Vin+ to highest project voltage (red wire)
- Load GND/lowest potential to Shared board GND
If you wish to measure the low-side of your load/circuit, instead of the high-side, then follow the low-side wiring instructions on this guides Arduino page.
Usage
Connect your board to Adafruit IO Wippersnapper and navigate to the WipperSnapper board list.
On this page, select the WipperSnapper board you're using to be brought to the board's interface page.
If you do not see your board listed here - you need to connect your board to Adafruit IO first.
On the device page, quickly check that you're running the latest version of the WipperSnapper firmware and that your device is Online.
The device tile on the left indicates the version number of the firmware running on the connected board.
- If the firmware version is green with a checkmark - continue with this guide.
- If the firmware version is red with an exclamation mark "!" - update to the latest WipperSnapper firmware on your board before continuing.
Next, make sure the sensor is plugged into your board and click the I2C Scan button.
You should see the INA228's default I2C address of 0x40 pop-up in the I2C scan list.
First, double-check the connection and/or wiring between the sensor and the board.
Then, reset the board and let it re-connect to Adafruit IO WipperSnapper.
With the sensor detected in an I2C scan, you're ready to add the sensor to your board.
Click the New Component button or the + button to bring up the component picker.
Adafruit IO supports a large amount of components. To quickly find your sensor, type INA228 into the search bar, then select the INA228 component
On the component configuration page, the INA228's sensor address should be listed along with the sensor's settings.
The Send Every option is specific to each sensor's measurements. This option will tell the Feather how often it should read from the INA228 sensor and send the data to Adafruit IO. Measurements can range from every 30 seconds to every 24 hours.
For this example, set the Send Every interval to every 30 seconds.
Your device interface should now show the sensor components you created. After the interval you configured elapses, WipperSnapper will automatically read values from the sensor(s) and send them to Adafruit IO.
To view the data that has been logged from the sensor, click on the graph next to the sensor name.
Here you can see the feed history and edit things about the feed such as the name, privacy, webhooks associated with the feed and more. If you want to learn more about how feeds work, check out this page.
