Re: Multichannel Gas Sensor with MKR1000

Point 1: already present on my sketch.
Point 2: modified the cpp as your direction but with NO LUCK... now I pass the initialization of the sensor but it freeze when I try to read a measure (note that the sensor work also with WIO node).

4-Channel SPDT Relay make MKR1000 hangs

I'm triing for make works MKR1000 with 4-Channel SPDT Relay, but even if the relay board is connected (via I2C) or not... it's sufficent to insert in the sketch the declaration #include <multi_channel_relay.h> Multi_Channel_Relay relay; to hangs the MKR1000; the most strange fact is that the MKR boa...

Multichannel Gas Sensor with MKR1000

I've two Multichannel Gas Sensor and no one talk with MKR1000. First guess is oriented to the I2C voltage level of the MKR that's 3.3V so I've tried with a Seeeduino 4.2: first a 5V and all was good, then I switched at 3.3V and tried again... the Gas Sensor still works! So... why works a 3.3V with S...

LoRa RF95 home network. What to expect?

I'm building a little domestic LoRa network, I would want to use a lora module (mounted onto a SAMD board) as "gateway" that will route oncoming RF packets RF to a MQTT server; I've some RF devices on my network that asynchronously sends data... so, my question is: what appen if multiple devices tra...

Hi folks, I would want to use a LoRa module with a board with multiple serial like Mega but the library published by seeed studio seem to be concepted to use with only software serial. I tried also to use the RadioHead "cousin" library (actually the seeed studio library seem to be a fork of radiohea...

Re: Burn booloader on Seeeduino Lotus

Ok... based on the fact that the CPU is the same of UNO, I tried to burn the UNO bootloader with the Arduino ISP... now the Seeeduino board seems to works right.

Electricy sensor bad reading

I've attached the sensor to my Arduino Uno and uploaded the example sketch posted in the Wiki. I obtain very strange and enormous value, the reading is in some ways related and to the real utilization (a 18W lamp)... when I turn OFF and ON the lamp the value change, but the value are really very big...

Re: Longer Groove Cable needed

I've solved the problem! Now I can use upto 2.5mt of I2C and 1-Wire also... the problem (in my case) was that, using a grove shield (obviously), two digital I/O are coupled on the same cable and connector, so I've used the caution to use only one I/O per cable in the software. Now can use both flat ...
