Alex's Corner - Week 5 - Sensors, Libraries and More!
-
Hi Everyone,
I will be running the next webinar at 2 pm (GMT) Thursday the 27th of April, demonstrating how to connect various types of sensors to your Pycom devices as well as how to re-write Arduino/other MicroPython Libraries to be compatible with your Pycom boards.
The format will be as following:
- Introduction
- Explaination of the differences between MicroPython & Arduino
- Demos
Please do ask any questions (either here or in the livestream chat), I'll try to answer them live!
Visit this link next week, on the 27th of April to join in!

Cheers,

@bucknall Any chance of Resin on the Wipy? https://resinos.io/ There is now a Home-assistant install using resin described here https://community.home-assistant.io/t/introducing-hass-io/17296

@bucknall @livius
The ADXL345 module from Adafruit does have a 3.3v regulator but - like most Adafruit stuff - it will pull up the I2C bus to Vin.
-
@livius both the LCD and ADXL345 have 5 V to 3V3 regulators. I believe the LCD's backlight requires 5 V but it's data sheet isn't particularly clear!

@bucknall
I have question about voltage.
I see on video (4 minute) that you connect 5V from expansion board to all devices
What about voltage on I2C pin then?
-
Apologies for the delay, we're starting a little bit late today due to some maintenance being done in our office! Will be starting at half past 2pm!
-
Quick update - I'm postponing the community showcase as there were some people unable to join for the date which I outlined.
I still very much intend to run this showcase and will create a new post closer to the time.
In the mean time I will host another Alex's Corner explaining how to import libraries and re-writing MicroPython/Arduino Libraries to be compatible with the Pycom devices.

@bucknall sounds interesting! One thing that could help get started is to release a raspberry pi image (.iso) with everything configured and ready to go, this makes life very easy :-) e.g. https://home-assistant.io/docs/hassbian/installation/
-
@robmarkcole This should fit the use case then!
The main idea is being able to set it up with just a quick install script using a product called Resin. It will run it's own Node-Red instance and also support it's own MQTT server so you can retrieve your LoRa messages via MQTT.
-
@bucknall OK great! I have a couple of projects that want LowRa to monitor various services on the estate I live on :-)
-
@robmarkcole Yes 27th haha my mistake!
I'm actually working on something to publish regarding the RPi 3 and LoPy as a gateway
-
You mean, thurs 27th?
Btw is anyone doing a project to setup a pi and a LoPy as a Lowra gateway?
