TWelcome @Piyush5117! Can you share your technical background and any projects you're working on? Welcome to the server and we're glad to have you as a DevHead!
NThis is quite crazy https://www.linkedin.com/posts/vemundbakken_onio-madeinnorway-epishine-activity-7151621604580491264-Rryk?utm_source=share&utm_medium=member_desktop
This was a nice team effort at #onio and possibly the northern most made remote control ever designed #madeinnorway. It is certainly the lowest energy one -…
TArduino Pro equipped with Bosch environmental sensors and IMU from Sensortec booth at CES
TDigi Xbee and Qwicc sensors from Sparkfun. More of this and them on the way to server.
T@Padmalaya Rawal I didn’t spend a lot of time in south and central hall where Doosan and a few of the other big robotics booths were so I didn’t see a ton of robotics beyond glorified Roombas being used as lawn mowers, etc.
@Petr Dvořák I scheduled a call with the neuromorphic chip co for after the show so will follow up once I have a story.

KHey guys, any ideas on how to make proximity-activated locks except for ultrasonic sensors? We're trying to make a lock that is activated based on the signal distance of a receiver to the transmitter.
NLiDAR if you to have a longer range, or RFID if tap based are some things I can think of. Now that you've specified it to be based on Tx/Rx distance, check out BLE beacon based usage. You can use RSSI values t translate to distance in meters and set a threshold point for door lock/unlock.

KCan anyone assist me for learning IOT and embedded systems development
I have been learning about different microcontrollers (UNO,ESP32,NODEMCU) and C, C++
Kindly give me a roadmap to follow!

NI feel there is only just-do-it map.

NIt's okay to do things in bits and pieces as you encounter new things. Knowing the vastness is needed and so this one.
UHi, @K.L.NAGARAJU I'd suggest starting with a simple 8-bit MCU like Arduino Uno board. With it learn how to program MCU, memories, and peripherals (fundamentals like how all works). Then, try to interface various sensors using protocols like Serial UART, I2C, and SPI. Later, pick a 32-bit ARM MCU, and get comfortable with 32 bit registers and operations. And finally, start building projects around the area of your interest. I hope this may help. Best wishes!
KThanks a lot sir! @Umesh Lokhande
UWelcome
K@Navadeep what if like, i want it to activate based on the distance of a self-made, wearable device?
KSo that only that person with the device is locked off ?
NOne way is to have a packet transfer between two nodes where you authenticate with keyword along with distance calculation.
NLet the transmitter be a beacon with the user sending unique bits. Receiver knowing the location of that bit in the datastream can authenticate from there.
NCrude solution - got to see what standars exist in place for this type of application.
KOhhhh ok i see
N@Yeshvanth Muniraj hop in for this one dude.
KIs this doable in an arduino?
KWe are doing a research proj but this is just for proposal
KAre you referring to the Ultrasonic sensor?
NNah, the RF stuff. He's been working on this for a while now - packet transfer, protocol stack etc for automotive applications.
NYeah - got to interface wireless module on top of that though.
NPerfect. Good luck on that @Kamaruu
KOhhh nc nc
KThanks man, i really appreciate your help
NNC Not connected? 
KXdxd no noooo
TWe will also be launching a series of videos in the server next week that help get around common problems encountered by different types of developers so be sure to keep an eye out for that!

I have been facing a trouble shoot with RFID interface NODEMCU

Nokay, you're already shooting the trouble!
Ndid Umesh's suggestion help?
KStill expected output not there yet!
NWhat's happening now. Please explain.
KSure
KActually I'm trying to make my nodeMCU interfaced RFID reader, to read an RFID card or tag and to display the UDI of that particular card on the serial monitor!
K
KCode writing and compilation is done!
No error founded
No error founded

KBut I didn't find the expected output
NOkay, let's take this bit by bit:
- cross check if your SS pin defined in code and hardware are the same - that's the only variable I notice in the code.
- UID is from the RFID tag. Are you placing the card on top of the reader? The main loop continually keeps scanning.
- If you doubt over hardware or connections made, hook a logic-analyzer and check the SPI frame.
K"I'll give it a shot and I'll update you shortly."
NI suppose the system didn't find a card at all. If so, the "Card_UUID: " will defacto print in the serial terminal.
