Makers, hobbyists and electronic enthusiasts looking for a project to keep them busy this weekend may be interested in this awesome Arduino temperature and humidity sensor which has been created ...

I used an LCD shield to display the current temperature and speed of the fan, but you can use the circuit without the LCD display. You also need to select the transistor by the type of fan that you ...

After some searching, I ended up using a microcontroller and a piece of code borrowed from the web that I tweaked and adapted. The microcontroller-based concept was chosen because I wanted to scale ...

– A Photoresistor – A Potentiometer – A TMP36 temperature sensor – A HC05 Bluetooth module (not compatible with Apple iPhones) “If you don’t have an Arduino Uno and Mega board no problem!

Luckily, Arduino’s own cloud services make it surprisingly easy to code for the Oplà. I opened the box, plugged the board into the Carrier, and then connected the board to my computer.
