Today, we will learn how to build your own stand alone Arduino on breadboard

Components Required

pin mapping diagram for AtMega328p

Here pin mapping diagram describes each and every pin need to be connected, pin No 1 of (AtMega328p) is connected to the reset switch, and a pull up resistor is also connected to the switch to ON state, pin No 7 & 20 connected to (+5v), pin no. 8 & 22 connected to (GND), pin no 9 & 10 connected to 16 MHz Oscillator to generate clock pulse coupled with two 22pF non electrolytic capacitors, an indicating LED is connected to pin no 19

Connections

Wire configuration to upload code to stand alone Arduino

in this step we will use an ARDUINO UNO(Without IC) as a programmer to program our stand alone circuit

ARDUINO PINS >> ATMega328p
Reset Pin-------Pin no one
Tx pin----------Pin no three
Rx pin----------Pin no two
5v--------------Pin no 7
GND-------------Pin no 8
