This is one of my bucket list the CNC – Mini Laser Engraver. You probably have seen one come by at one point. This is an blog on how I made an Arduino CNC – Mini Laser Engraver for wood and Thin paper, Just using some old DVD drive stepper mechanism and a 250mW laser. …
Through some researches I did online on how to minimize components use, I stumbled with using an ATTiny13A chip to be used in the project. And through some more researching, I decided to have my new project done using the ATTiny13 Chip. ATTiny13 Chip I bought these chips from Ali-Express. First I need to study …
The I²C bus communication is one out of three possible communication protocols, the ESP8266 is able to communicate with other devices like OLED displays, barometric pressure sensors and so on. The two other communication protocols are SPI and UART. I²C stands for Inter-Integrated Circuit was invented 1982 by Philips Semiconductor (A Dutch company), now NXP …
I’m currently working on a project that requires a cheap, low-power micro-controller that’s programmable through Arduino and has a few more pins than the “standard” ATtiny85 micro-controller. That’s where I found the ATtiny84 and the ATtiny2313. It has many of the same features as the ATtiny85, but has 12 I/O pins / 18 I/O pins …
I have only started electronics as a hobby and it has been a great learning resource for me so I am far from any type of expert. But I like to share my knowledge. I wanted to change the logo on my OLED display. It took me days to work it out thanks to very …
I need a remote that I can program and that will work on batteries for a long time. So I was thinking of using a ATTINY with a way that enables me to send the information over the air. And when it comes down to having inexpensive yet reliable 2-way RF solutions, no one does …

In this blog I will show you how to program a ESP32S and a ESP32 + CAM as I use these the most. It fairly the same as the ESP8266. There’s an add-on for the Arduino IDE that allows you to program the ESP32 using the Arduino IDE and its programming language. In this tutorial …
How to program a ATTiny I discussed in my previous blog here. But I want to go even smaller! In stead of using the “big” DIP IC housing I wan to use the smaller SOP IC housing. But then I realized how to program these tiny things, they don’t fit on a breadboard. But first …
Recently I was working on a new project here. For this project I need an Arduino Nano V3.0 Clone. After I had finished my code, I wanted to upload the code to the Arduino Nano with Arduino IDE. However, this did not work. After having a search on the internet, it turned out that I …
