Micro Weather Station
- Hosts: Brian and Andy
- 2/29/20
- Build a Micro Weather Station using a Wemos D1 Mini, 1.3" OLED display, 3D Printed enclosure
Materials
- Wemos D1 Mini 4M (Not the lite version with 1M)
- https://docs.wemos.cc/en/latest/d1/index.html
- You can buy them on Ali Express (takes about 3 weeks) or Amazon (2 days)
- programmable with Arduino or microPython. We will be using Arduino
- OLED Display 1.3"
- very common display that can be found on Amazon, eBay or Ali Express
- uses SH1106 chip so you have to use SH1106 library in your code
- I2C serial connection
- pinout is VCC, GND, SCL, SDA
- example but you can get cheaper: https://www.amazon.com/HiLetgo-Serial-SSH1106-Display-Arduino/dp/B01MRR4LVE/ref=pd_sbs_147_t_0/139-4905825-1461144
- you can also use a 0.96" screen but that one uses a different chip for the driver so you have to set your code to use the SSD1306. If your screen lights up but screen is garbled then this is the case.
- 3d Printed Enclosure
- search for "D1 Mini 1.3" on Thingiverse
- https://www.thingiverse.com/thing:2934049
- https://www.thingiverse.com/thing:3044478
- Misc
- Dupont wires - these push onto the header pins.
- Solder
- assorted 2mm self taping screws
- hot glue
- donuts and coffee
Instructions
Setup the Wemos D1 mini for the Arduino
- good tutorial here https://averagemaker.com/2018/03/wemos-d1-mini-setup.html
- overview
- install ch340 serial usb drivers
- install Arduino IDE - not the web version
- Add the json string to the board manager URLs in file->preferences http://arduino.esp8266.com/stable/package_esp8266com_index.json
- Set the board in Arduino
- Get the blink example working
hook up the screen
- Solder dupont headers to 5V, Gnd, D3 and D4 on the Wemos D1 Mini
- Slug other end of dupont headers to oled screen
