What is the ATmega328 chipset used for?
Applications. ATmega328 is commonly used in many projects and autonomous systems where a simple, low-powered, low-cost micro-controller is needed. Perhaps the most common implementation of this chip is on the popular Arduino development platform, namely the Arduino Uno and Arduino Nano models.
How much current does Atmega328p use?
Referring to the data sheet containing information on the Atmega328p (http://www.atmel.com/images/Atmel-8271-8-bit-AVR-Microcontroller-ATmega48A-48PA-88A-88PA-168A-168PA-328-328P_datasheet_Complete.pdf), it states that the power consumption of a 1Mhz, 1.8V, 25C operating mode consumes 0.2 mAs of current.
How much on chip RAM is contained in an Atmega328p microcontroller?
An ATmega328 has 32 KByte of flash memory, enough to store fairly substantial sketches. When an ATmega is powered up, it starts executing the code stored in its flash memory. RAM memory is the work memory where variables, buffers, strings, and other bits of data reside which get used and changed by the running sketch.
What does 328 mean in ATmega328?
ATmega328 is an Advanced Virtual RISC (AVR) microcontroller. It supports 8-bit data processing. ATmega-328 has 32KB internal flash memory.
How much current can an Arduino Uno supply?
There are 16 digital pins on the Arduino board. They can be used as inputs or outputs. They operate at 5V and have a maximum current draw of 40mA.
How many pins are in the ATmega328P microcontroller?
The ATMega328P is a microcontroller with 23 IO pins, two 8-bit internal clocks, and 32kB of flash memory. To begin, notice the notch that indicates the direction of the chip — and the dot that indicates Pin 1. All pins that follow suit are in regular numerical order.
Do you need voltage regulator for ATmega328 battery?
Since you want to use a 9V battery, you will need some sort of voltage regulation to push it down to acceptable levels for the ATmega328. You chould use a linear voltage regulator like this one for example.
What’s the easiest way to power an ATmega?
The next step is to wire the programming adapter. You can take any path to wire it in, as long as you use the correct pins. Optional: If you are going to power your ATMega with the programming adapter, then wire from the “GND” and “+5V” pins on the adapter, across to the power rails.
How can I add a led to my ATmega?
Add a LED to the first available row next to Pin 1 that is not already being used by the ATMega. Add a 330 Ohm Resistor from Pin 1 to Power. Pin 1 is the reset pin. Then, add another 330 Ohm Resistor from Pin 4 to the row that the LED is connected to.
