This video is about ATtiny85 Microcontroller IC. The ATtiny85 is a microcontroller in a similar vein to the Arduino. It has some advantages and disadvantages compared to Arduino. The main advantage of this IC is it's price, small size and low power consumption. It costs about 1-2USD only. But, It has less I/O Pins and smaller memory. Moreover, not all arduino functions will work with this IC. Thus, it is suitable for small Arduino projects. | Electronics-BD
