Damm I am trying to get this working with a Arduino pro mini ,,but no luck wanted to use it in the car ..
How do you wire the NRF24L01+ ???
N-Channel Mosfet s ??? model number please any help much appreciated
I have tried mosfets >>>irf510n
Wow, great! Its alway nice to see others using my work too. Your code improvement seem to be very helpful too.
I have most recently also integrated this directly into my gateway build (see here). I am still struggling with code there though.
@yveaux said in Ikea Molgan Hack:
@magpern the instructions on openhardware.io state that the Molgan must be battery powered while programming:
Well, then I can confirm that you don't have to power the Molgan from batteries just for programming. Burning the bootloader works fine with just power from the ISP port and programming it through FTDI works fine if power comes from the FTDI.
What I found wierd is that the atmega328 had power, the radio had power, it wrote debug messages to the FTDI - when powered through the FTDI, it send radio messages etc, but it just did not receive messages.
Messages where not received until I supplied power to the + / - pads (battery pads).
I did read the instructions on openhardware.io, but I didn't follow then to the t.
New to electronics and progamming.... hence excuse rather dumb nature of my query .. recently purchase the Devduino V2.2 OTA version and am trying to figure out if the device comes pre loaded with the arduino bootloader. ??
@HouseIOT Sorry to trouble you, i use a mysensors-wifi-gateway with protocol 2.1.1 , and my homeautomation is home-assistant. I can't use your dimmer in my system.
After read the reference, there need to add V-percentage and V-status in the code, as a newbie , I can't do it myself. So I wondered，can you do me a favor?
Thanks a lot.
@GLAB You can set the frequencies using the settings in MyConfig.h, which is in the MySensors folder. If you put any of the defines from MyConfig.h into your sketch, they will override the MyConfig.h setting for that sketch only.
If you are using the RF24 radio, there are different channels which correspond to a given frequency. The default is channel 76. There is a list of typical channels in MyConfig.h. If you want to change the channel for all the sketches, change it in MyConfig.h. If you want to change it just for the sketch, add a define to the sketch. For example:
#define MY_RF24_CHANNEL (84)
The problem with changing the channel in a sketch is that the gateway has to be on the same channel to receive from the node. So, normally it makes sense to change in MyConfig.h because you usually want the gateway and all the nodes on the same channel.
Other radio's like the RFM69 list the frequency instead of using a channel. They can be overridden in the sketch as well. You can find the defines that are needed in MyConfig.h
