How to Program ATmega16 on Breadboard using USBasp (Windows 10/11)
If you have ever tried programming an AVR microcontroller on a modern Windows system, you already know the real struggle is not the code — it is getting USBasp to work reliably on Windows 10 or Windows 11.
In this tutorial, I walk through a complete, working, no-shortcuts method to program the ATmega16 microcontroller on a breadboard, using USBasp, Microchip Studio, Zadig, and AVRDUDESS.
This guide is written to match the video step-by-step, so you can follow along without guesswork.

What You Will Learn
By the end of this tutorial, you will know:
How to program ATmega16 on a breadboard (no Arduino)
Correct USBasp ISP connections
How to fix USBasp driver issues on Windows 10 & 11 using Zadig
How to create and compile an AVR project in Microchip Studio
How to upload HEX files using AVRDUDESS
How to avoid common AVR programming and fuse-related mistakes
Hardware Required
ATmega16 microcontroller (PDIP package)
Breadboard
USBasp ISP programmer
Jumper wires
LED + resistor (for testing)
USB cable
Software Required
Microchip Studio (for writing and compiling code)
Zadig (for USBasp driver installation on Windows)
AVRDUDESS (GUI tool for uploading HEX files)
All tools used in this tutorial are free.
Step 1: ATmega16 Breadboard Setup
Place the ATmega16 on the breadboard and make the following mandatory connections:
VCC → +5V
GND → GND (connect both GND pins)
AVCC → +5V (very important, even if ADC is not used)
RESET → USBasp RESET
Without AVCC, ISP programming becomes unreliable.
Step 2: USBasp ISP Connections
Connect USBasp to ATmega16 as follows:
MOSI → PB5
MISO → PB6
SCK → PB7
RESET → RESET
VCC → VCC
GND → GND
Double-check wiring before powering up.
Step 3: Fix USBasp Driver on Windows 10 / 11
This is where most beginners get stuck.
Steps:
Connect USBasp to PC
Open Zadig
Select USBasp device
Install libusbK driver
Once installed correctly, USBasp will be detected by programming tools without errors.
Step 4: Create Project in Microchip Studio
Open Microchip Studio
Create a GCC C Executable Project
Select device: ATmega16A / ATmega16
Write your Embedded C code
Build the project to generate the HEX file
This tutorial uses a simple LED blink program for verification.
Step 5: Upload Code using AVRDUDESS
Open AVRDUDESS
Select programmer: usbasp
Select MCU: ATmega16
Load the generated HEX file
Click Program
If USBasp and drivers are set correctly, the upload completes without errors.
Common Problems & Fixes
USBasp Not Detected
Reinstall driver using Zadig
Use libusbK (recommended)
Code Upload Works but Timing Is Wrong
Fuse bits may not match clock configuration
Verify internal vs external clock settings
Signature Errors in AVRDUDESS
Check ISP wiring
Enable slow SCK
Ensure AVCC is connected
Why This Method Works Reliably
Uses official Microchip tools
Avoids outdated drivers
Avoids Arduino bootloaders
Follows proper ISP and power requirements
This makes it ideal for students, beginners, and professionals learning pure AVR embedded systems.
Who This Tutorial Is For
Beginners learning AVR microcontrollers
Students working with ATmega16
Engineers moving from Arduino to bare-metal AVR
Anyone frustrated with USBasp on Windows 10/11
Final Thoughts
Programming ATmega16 on a breadboard does not need to be painful — even on modern Windows systems.
Once USBasp drivers and ISP wiring are done correctly, AVR programming becomes simple and reliable.
