Tiniest USB development board with Micronucleus
https://www.electronics-lab.com/tiniest-usb-development-board-micronucleus/
Development board for the ATtiny84a with USB connector. Pre-loaded with the Micronucleus bootloader compatible with Arduino. DIP version with USB connector of the ATtiny84a. The board can be placed in the middle of the breadboard. Sketches can be uploaded from Arduino using the Micronucleus bootloader. There is an indicator LED to determine if the board […]
Minimal ATSAMD21 Computer is Arduino compatible
https://www.electronics-lab.com/minimal-atsamd21-computer-arduino-compatible/
This project describes how to build an ATSAMD21-based computer on a prototyping board using the minimum number of components, and program it from the Arduino IDE. David Johnson-Davies writes: I give two alternative methods of uploading a bootloader to the bare ATSAMD21 chip using the Arduino IDE. You can then program the minimal ATSAMD21 computer […]
Programming Atmega328p Microcontroller with Arduino IDE
https://www.electronics-lab.com/programming-atmega328p-microcontroller-with-arduino-ide/
Over the past few tutorials, we have mentioned several scenarios where using any of the Arduino board in a project may be an overkill due to the cost, size, and more technical reasons such as high power consumption. In the last tutorial, we discussed an alternative way of using Arduino, i.e. using the Atmega328p microcontroller alone […]
Installing the Arduino Bootloader on the Atmega328p Microcontroller
https://www.electronics-lab.com/installing-the-arduino-bootloader-on-the-atmega328p-microcontroller/
Cost and size, just to mention a few, makes using an Arduino board in certain projects an overkill, often times its always too big, or too expensive for the scope of the project especially when it’s a project that we need to make several units. One good way to retain the simplicity that comes with the […]
$2 Arduino – ATMEGA328 as a stand-alone
https://www.electronics-lab.com/2-arduino-atmega328-as-a-stand-alone/
In this tutorial you will learn how to use ATMEGA328 microcontroller as standalone Arduino. This way you can minify your next arduino project. They cost only 2 bucks, can do the same as your Arduino and make your projects extremely small. We will cover the pin layout, how to make it ready for the Arduino […]
DIL-Duino – Arduino in a DIL shape
https://www.electronics-lab.com/dil-duino-arduino-in-a-dil-shape/
DIL-Duino is a complete Arduino environment in a DIL-8 form factor based on the DigiSpark Hardware. by Daniel Grießhaber: DIL-Duino uses the QFN Version of the ATTiny85 and a USB Bootloader to provide the easy to use Arduino stack in a single DIL-8 Package Footprint. To fit the Micro-USB socket on the board, it was […]
DIY Bare Minimum Arduino Mega 2560
https://www.electronics-lab.com/diy-bare-minimum-arduino-mega-2560/
MichaelC349 @ instructables.com has designed an Arduino Mega 2560 board with bare minimum components and small size. The resulting board is bootloaded using an Arduino UNO and an external USB to serial adapter is used to program it. Personally to be used for robotics projects that require ATmega2560’s 256 KB flash and digital/analog pins, where […]
How to burn an Arduino UNO bootloader to a new ATMEGA328P-AU chip
https://www.electronics-lab.com/how-to-burn-an-arduino-uno-bootloader-to-a-new-atmega328p-au-chip/
This video shows the steps to burn the bootloader from an Arduino UNO, to a new ATMEGA328P-AU chip. The new chips are the TQFP 32 type package. How to burn an Arduino UNO bootloader to a new ATMEGA328P-AU chip – [Link]
Burning Arduino Bootloader on ATMega328 using USBasp Programmer
https://www.electronics-lab.com/burning-the-bootloader-on-atmega328-using-usbasp-programmer/
In this tutorial, you’ll learn how to burn Arduino bootloader on a new ATmega328 using USBasp ISP programmer. Every Arduino Uno Board comes with a microcontroller called the Atemga328P, and they are already pre-program with Arduino Bootloader firmware. Therefore, there is no need to burn Arduino bootloader into those Atmega328P chips again. Here, we will […]
