Maybe very interesting for STEM courses realize a sort of simulator like BBC micro:bitfor UiFlow (at least for the graphic UI)

Could help to understand the behaviour before to have the phisical device.
thanks

Hello, could be great to simply include/upload libs already shared for micropython (eg putting in a /lib path). It may expand a lot of capabilities (eg for HW ds18b20 or for SW Email sender etc). Better if Blockly section of UIFlow could accept some changes applied to Python section (at least the values)

@zontex thanks to answer, just to have confirm it is "safe" use a LDO to work at 3.3, i'm planning to connect one ENV II unit and at the same grove port A input pin 32 (or 33) of a Core 2. My doubt came from observe ENV unit schematic, where DHT 12 pin have pullup at 5V. Btw i don't have problem to put a LDO, my goal is share both sensors (one M5Stack and another external DS1820

Question: Grove PORT A for two sensors, i need to measure temp via 1-wire Ds1820, and Humidity, Pressure etc via i2c ENV II Unit. Someone has tried before? Further, is better use LDO (HT7533 or AM1117-3.3) to power DS1820, to avoid burn input pins (aren't 5V tolerant?). Any other minimal solution? (voltage divider etc).

@m5stack https://www.hackster.io/gperrella/m5-covid-bastion-074bb8 Hello this is my second project based on M5 ecosystem related to Covid solution to slow its spread. The main objective of this conceptual project is to demonstrate a way to control access to the offices of employees of a small company or members of an association.

Hello, here my project to contribute at this contest https://www.hackster.io/gperrella/m5-covid-sentry-a-covid-19-disease-monitor-479cd8
Hope it can help someone.
Project is still work in progress, stay tuned!

@world101 sorry for delay on answering. Many thanks it works as expected! In the meanwhile i tried with upython language also to manage more complex json structures.

Hello, i'm a beginner of UIFlow and M5Stack, just tried to parse json from this example code, but doesn't work for me, no json node extract, so compare Failed message. I'm able to download whole json data with the command LCD.Print GET DATA. Someone has success with json code samples?

Thanks in advance
