| + | I obtained a great thermometer that I can use in my house or anywhere else. You just need to plug it to a power source and it will tell you the humidity and temperature wherever you are. | ||

| + | Try using genuine arduino wifi boards, some of the other ones are not well maintained in matters of drivers. I've had problems for days with the NODEMCU ESP8266 wifi because the micro sub to usb drivers do not work and the board is simply unusable. I tried 7 different micro usb cables, tried programming it with 3 different computers with the drivers installed on each one. **NOTHING WORKED**. Checked arduino.cc forum and most people have the same issue, it's unusable. I chose to change my project a little bit so I can work it out. | ||
| + | Instead of making it read data from sensors and transmit them to arduino IoT cloud, I made it read the data from the sensors and show it on an LCD screen. Now it works perfectly fine, the only thing i need to find now is a power source. | ||
| + | I recommend informing yourself about the things you want to buy if they're not genuine since some of them have issues and **will not work**, making it a hard time for you. | ||
