ESPectro Blynk Firmware

Using ESPectro with Blynk with almost no coding required.

IDE Compatibility

• Arduino IDE
• PlatformIO

Dependencies

You have to install the following libraries:

• Blynk
• ESPectro
• NeoPixelBus
• WiFiManager
• Adafruit BMP085 Library

However, if you're familiar with PlatformIO, you only need to download Adafruit's BMP085 Library manually to lib directory!

Blynk's Virtual Pins

We use Blynk Virtual Pins for:

• Controlling NeoPixel + adjust LED color.
• Reading Adafruit BMP sensor data (temperature, humidity, pressure).
• Set analog reading threshold. If the reading is below the threshold, the firmware will attempt to send HIGH value to GPIO 10 (used to toggle ConnectIO).

Here's the pin mapping:

Virtual Pin No.	Used as	Read / Write
0	NeoPixel LED switch	Write
1	NeoPixel red color (0 - 255)	Write
2	NeoPixel green color (0 - 255)	Write
3	NeoPixel blue color (0 - 255)	Write
4	Temperature	Read
5	Pressure	Read
6	Altitude	Read
7	Sea-level Pressure	Read
8	Analog reading (A0) threshold	Write
