    Arduino Nano Capacitance Meter

    Why don't you design your own character for "µ" instead of using the silly "u"? If my memory serves me right, you can design up to 8 custom characters with these LCD displays. Imagine how much more professional would your project look.

  • Temp & Humidity Sensor with LCD Disp & LED Indicator

    Hi Raul. The instructions how to make custom characters are in the LCD data sheets. If you do not have the data sheet at hand, google "how to create custom characters on 16x2 lcd" . Here is one of them to get you started: https://www.arduino.cc/en/Reference/LiquidCrystalCreateChar Good luck. abbabba

  • Temp & Humidity Sensor with LCD Disp & LED Indicator

    Hi Rahul, nice project. I do have some comments to make. Please do not take it personally, as this is for the benefit of those who would like to recreate your device. For the start when you specify temperature accuracy in your specifications, do not put degrees Celsius after the % sign. You either say ± 2 °C, or ± 2 %, but not both. Now to the LCD. You can create your own characters with these displays (I think up 4 off, check the data sheet) so you can make degrees symbol instead of apostrophe. OK and last comment, probably the most important. The use of LEDs without series resistors will most definitely damage your ports on the microcontroller eventualy. Use one resistor around 470 Ω to 1kΩ in series with each LED. Good luck and keep at it. It's fun...
