AVR Training



AVR microcontroller series is one of the most widely used microcontroller families in hobbyist and beginners embedded electronics space currently. The high acceptance of AVR microcontrollers is mainly credited to Arduino hardware and software series. AVR chips are 8 bit microcontrollers based on RISC architecture. AVR chips were developed by Atmel.


We will be using Atmega328 microcontroller during this course. This microcontroller is widely used by enthusiasts who are in the initial phase of their embedded electronics journey.

Some of the capabilities of Atmega328 microcontroller is listed here”-

Below given experiments have been developed for maximum learning from the hardware and software side.

1 Flash LED at an observable rate. MV1
2 Hello LED – Flash LED at a rate such that the LED appears always on. Estimate the onset of the rate when the LED appears to stay on MV1
3 Controlling ON/OFF of an LED using switch MV1 OR MV2
4 Use LFSR based random number generator to generate a random number and display it MV1 OR MV2
5 Toggle the LED every second using Timer interrupt MV1
6 Use the potentiometer to change the red LED intensity from 0 to maximum in 256 steps MV1
7 Use the switch to select the LED (from RGB led) and then the potentiometer to set the intensity of that LED and thus create your own color from amongst 16million colors MV1
8 Read the ADC value of the voltage divider involving the LDR. Print the value on the serial monitor MV1
9 Use the LDR and estimate a threshold for the LDR value and use that to turn the RGB LED on, to simulate an ‘automatic porch light’ MV1
10 Use the thermistor to estimate the temperature and print the raw value on the serial monitor MV1
11 Connect the LCD I/O Board and print ‘Hello World’ on the LCD. Scroll display from left to right MV2
12 Use the on-board EEPROM to store the temperature min and max values together with a time stamp MV2
13 Speed control of D.C. motor MV3
14 Speed control of Stepper motor MV3



More than 50+ experiments and activities are possible using the above given hardware setup. Course learners have come up with various projects using these peripherals boards. All the pins of Arduino Nano board are exposed hence one can easily make appropriate connections with any type of electronics components.
