Nano SIM දැන් ලංකාවේ......
සමහර දුරකතන වලට අපි සාමාන්යයෙන් භාවිතා කරන SIM හරියන්නේ නෑ...දෙවන රූපේ තියෙන්නේ ඔය කියන සිම් වර්ගේ........ලංකාවේ අපට (nano sim) නම් Dialog තමයි
Climate Control with Arduino Nano for a Peugeot 406 !
My friend's car had a cabin air temperature sensor malfunction and the A/C unit kept the compressor on all the time ! That is bad for fuel economy and freezes everything in the car when outside temperature is not that high , so this is a quick 1-day project we did to control the A/C compressor according to the cabin temperature. Simply put , a sensor reads the air temperature and turns off the A/C compressor when a set temperature("Set Temp") is reached , it turns the compressor back on if the sensor reads a temperature that is more than two degrees higher than the "Set Temp" . The set temperature is set using two push buttons (Up/Down) . At the heart of the system is an Arduino Nano which controls a relay which in turn controls the A/C compressor. Welcome message on the LCD display ! Loads of hot glue of course ! :D Quick and dirty circuit ! No custom PCBs for 1-day projects xD Up/Down Buttons Hides nicely in a comfy spot :P Watch the video to see it in actio...
