This is an OLED temperature display based on ATmega328p along with a NeoPixel led ring to display different colors depending on temperature. This is a small temperature display using a OLED with a NeoPixel Ring around it using MQTT on a ESP8266 and sending data to the on board...

SimonM83 has posted a new tutorial on how to implement an Arduino menu using a rotary encoder. The tutorial goes through the hardware setup and sample code is provided. Rotary encoders with centre-push buttons are cool input hardware for projects, especially if you want to be able to...

Here is a detailed guide on how to get started with ATMega328P microcontroller. The guide goes in details on how to setup it on a breadboard and how to upload your first code on it. and blink a led. The real benefit of using this microcontroller is that it’s only $4 US, whereas...

This is an Arduino powered Weather Station Project that can run on batteries for almost a year! In order to achieve that we use a bare ATMEGA328 chip along with some accurate sensors. We use the DHT22 temperature and humidity sensor, a BMP180 barometric pressure sensor, a BH1750 light...

ianjohnston.com has designed a nice power supply based on  ATMEGA328P and Arduino bootloader. The output is dual channel 0-24vdc @ 3A each, with preset constant current and independant voltage/current control. This isn't a full design blog but I've tried to document/add stuff as I...

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 -...

Well, Christmas may over but we think you may take a look at this well designed PCB Christmas tree and why not consider building it for the next year. Since I already have an Arduino, and I felt pretty comfortable with it, I decided to use it to control the LEDs. However a full...

Here is a nice tutorial about launching you first ballon into space. Also tracking device information is provided. Source is available here: There are a lot of reasons to put together a weather balloon launch. Its a great project for a STEM /STEAM class, it requires planning,...
