We know that Arduino UNO board comes with 13 Digital IO Pins and 5 Analog Input Pins.įor simple projects, this may be sufficient but if you want to develop a complex project with lots of sensors, a display unit (LCD or OLED), motor controls and communication (like Serial, which in turn takes away two IO pins), then you have to worry a little bit.
One of the main concerns with Arduino UNO is the number of Digital IO Pins available for using in our project. I have seen several projects developed using Arduino from simple motor control to complete weather stations with graphical OLED displays.
Arduino UNO has been the go-to board for beginners and hobbyists in electronics for implementing a wide range of applications.
