Hiletgo new version nodemcu lua wifi download

But when I goto Step 6 to selct Port, it shows grey and not selectable. Any help, please? But when I unplug and plug the module again, it seem to go back to its empty state What if we want to connect multiple sensors who needs 5V supply? Reply 3 years ago. Once you upload your code with the IDE it's in memory. So it becomes plug and play! You can take any 5v phone charger with the micro usb plug and boom! Just like plugging in an Alexa or a Roku to power. As for knowing your code is running you can do some start up process like blinking the led 3 times in sequence on start up to show you your code is running Or even blinking 3 times every minute ect.

As for connecting 5v sensors you are going to need to do some calcs and drop the voltage down to 3. By TheElectromania Electromania Follow. More by the author:. Paste the copied link and insert it in Arduino IDE using following sequence- File menu - Preferences- Paste copied link into the area shown in black box in above image.

Restart the Arduino IDE once again. Good luck for fun with this amazing system on board Osama Abdel-Rahman made it!

I have tried several different sketches other people have made and I choose this software because it does everything I wish to accomplish. Shows access points, hidden networks, channel numbers, WiFi devices, signal strength, and a great easy to use website interface. Full credit goes to its developer!! He did a great job and all the work. With that said I have messed with the children while they were watching YouTube.

I wrapped the battery bank with that sweet looking carbon fiber because it looked rough. Filed off the pans on the ESP so I can lay flat. And buy out the back of the Wi-Fi antennas so they can pin it and lay flat against the battery bank.

Battery bank easily lasts a day with continuous use with power to spare. Also you can still use it as a battery bank. I had to file back part of the antenna plastic so they would fold up and down without binding on battery bank. I also removed the screw caps to make it easy to attach the wires and sealed them up with some heat shrink tubing. As you can see I get significantly more access points after the antennas are added.

Increasing the range also makes it easier to find open Wi-Fi networks on the go. So here is what it looks like assembled. I used double-sided tape to hold the ESP chip in place. Hot glue to hold the antennas. I soldered the wire antenna wires to each side of the existing PCB Wi-Fi antenna to hopefully get the best results.

Your results may very. Now you can use this to determine what channel is best for your 2. You can also see hidden networks such as Chromecast and printers.

If you perform a station scan you can see how many devices are on a given channel. To give you an idea how compact it is here are some additional photos. Small enough to fit in your pocket. Portable so you can help out a friend or elderly family member. Or free open WiFi hotspots. Let me know if you liked this or drop me a comment. Thanks for checking this project out. Question 1 year ago on Introduction. I'm not tec David but I'm in need of tec advice.. How to find a hidden WiFi hotspot in the house.

Today everything can be run from programs right from the phone. In the same sense evil can be committed in the house by perverted people. A WiFi hotspot has been interfering with the house WiFi. And it has been seen and made obvious that someone is getting into the house.
