The part choice sets the power supply The ATmega128 is a 5 V part unless you deliberately buy the low-voltage variant: the ATmega128 is specified for 4.5–5.5 V at 0–16 MHz, the ATmega128L for 2.7–5.5 V but only to 8 MHz. Decoupling decides whether the ADC is usable. AVR042 asks for one capacitor per VCC/GND […]

This is my first time using the AVR. I like to learn using the ATTiny 2313, because it is faster than MCS-51, cheap and the circuit is very simple. The chip has only 20 pins. I was interested because I want to build a simple line follower robot controlled by this MCU. Board Construction The

Introduction of 89Sxx There are some 89Sxx development board, here is another one. I have designed this single side development board to be used as a tool for learning MCS-51 Microcontrollers, and for easy microcontroller project development. The 89Sxx development board features : 89Sxx 40-DIL based design, 89S51/52/53 In System Programming (ISP) through the 6-pin header
