thanks. the main aim of this is to run Nano board in lowest possible power. I agree with bare ics and stripping most of circuitry we can go very low power consumption. thanks for link.

yes u can. do not supply extra vcc when usb is connected to pc.
thanks glad to know
it all depends on how fast signals are you transmitting. for normal arduino enthusiasts voltage divider should do basic job.

hi I had not much time past months to work on projects hence havent updated anything further. HDD might have hall sensors too I am not sure though, once I had opened old hdd or cd drive and found hall sensor.but instead you can buy hall sensor and use for hdd motor rpm. depending on what exactly you want to do.good luck

i have another video on getting started with nodemcu. there you can find info about drivers needed for nodemcu. also in this instructions you should get info about drivers.
View Instructable »it is because onboard led is active Low. i.e. it will be On when you make D0 Low.

i do not have Mega so cannot give solution. but i think it has something to do with exact library for MEGA and also low level instructions to put into sleep etc.

it is because onboard led is Active Low i.e. it is connected to same pin but with internal pull up or down, i am not sure though.

yes, but it worked this way too for me :)

thanks
yes you can do all of that.
i have not understood your problem.
View Instructable »yes....indeed
- TheElectromania commented on TheElectromania's instructable Programming ESP8266 ESP-12E NodeMCU Using Arduino IDE - a Tutorial
yes you should be able to do that as far as i understand. but you need to check which pin no has pwm function and also modify code accordingly. good luck
i had this issue mostly when i use bad or low quality usb cable. try changing cable.

nice work

to the best of my understanding the output of hall sensor is from open collector ... if fan is not energized everything is just OFF

that is weird because if you are using nodemcu it should work without any additional steps.
sounds interesting. ..i haven't tried hooking up to internet. if you manage to do that please share...

just check if right pin no is selected in sketch and led is connected properly

hiin step two I have given link to my video giving details of library and installation procedure.good luck.

Hi,if i remember correctly, you should change the fan type to 0 i.e. your code on Line 33: should be fanspec fanspace[3]={{0,1},{1,2},{2,8}}; char fan = 0;change fan = 1; to fan = 0;good luck

esp communication error is mostly encountered by me when usb cable is not good, esp is connected to usb hub, improper driver, wrong board selected while selecting board in arduino ide. check if you can see usb device in Windows device manager, try to change baud rate of your usb port, use short usb cable , do not connect via usb hub.last option would be, try first to program usin esptool or lua loader, if it doesn't work even there then probably something is wrong in your hardware or in communication port. I have a video on my youtube channel about getting started with nodemcu using esptool.good luck

never heard or experienced such errors. not sure what might be causing this. but just quick guess is...have you selected correct nodemcu board in boards manager?have you installed esp8266 arduino core libraries properly?is your usb cable good?lastly do not connect it to usb hub.good luck.

I believe it should work by applying 9v through usb socket..but not sure. you also need to be very careful that you do not apply 9v to usb data pins.other way is to apply 9v via Vin pin of nodemcu. to the best of my knowledge the voltage regulator should take care of stepping down voltage to 3.3v.just a word of caution. ..I have confusion whether max voltage can be 5 v or 12v at Vin pin..because I read in some forums that we can apply max 5 v only to Vin pin. but my guess is 9v at Vin pin should work.good luck.
View Instructable »do u see Nodemcu board in Boards Manager as shown in step 5. If not, then seems you have not installed esp8266 core repositories as mentioned in previous steps.secondly please remember to restart your Arduino IDE after installing esp8266 core libraries.

esp is power hungry device. if ur pc detects esp for some period and dissappears later then- i noticed this issue if the usb cable lenght is too long or not good quality like those Blue colored usb cables commonly supplied with most of the Chinese web suppliers. when I used my samsung or nokia phone cable such issues were solved. if you cannot detect the nodemcu at all..evenin device manger in windows system then probably you will need appropriate drivers. I have given links to drivers used by me on my github page. I have tested those on win xp..win7 and win 8.1 pc...all work perfectly. please follow my videos on youtube about installation procedure. it is probably given in video of getting started with arduino nano... chip is same in both cases.. ch340 I guess.

I believe it should be possible to do what you said. I have not yet explored this further. You can try to send UDP data to rpi or use a web server on nodemcu and let rpi read it... these are just suggestions.i have been able to connect rpi to nodemcu via udp..but still to be explored. In few weeks i will upload instructable on this. may be that might somehow help you.
View Instructable »Are you stuck at Step 4 ? if so, make sure you are putting correct link http://arduino.esp8266.com/stable/package_esp8266com_index.json in the arduino preferences. Which version of arduino IDE are you using ? Try first exactly 1.6.7 version like i have used. once it works on this, then you can upgrade your Arduino IDE to latest version. or try to go to 1.6.5 version. i have followed the steps given in my instructable on 3 different PCs and they have worked perfectly for WinXP, Win 8.1 and Win 7.

thanks. yes it works with most of the adapters
