ESP8266 ESP-01 Programming Adapter
I started to invetigate a little bit in the ESP8266 ESP-01 WiFi board and I hate to have loose wires cluttering my workspace… I demand a cleaner one, hehe… So I decided to build a little breadboard programming adapter. This … Continue reading
Write an integer to the Arduino EEPROM
Today I faced the problem that I wanted to write an int (integer) to the integrated Arduino EEPROM. The Atmel ATMega328 chip has an address space of 0-1023 and each of these slots can save 1-Byte or 8-Bit (which is … Continue reading
How to avoid delay() – create a custom Arduino class – Part 2
In the previous blog post we learned how to avoid delay() if necessary. It would be very convenient when we are able to add a layer of abstraction to this code so when can easily reuse it if we need … Continue reading
Arduino and how to avoid delay() – Part 1
The main problem with using delay() in your Arduino sketch is simply: it will block the whole system for the amount of time you specified. Since your microprocessor is pretty fast compared to most of the delay() time he is … Continue reading
Arduino Mood Lamp / LED Cube
I wanted to build an Arduino mood lamp that worked without any buttons and is customizeable for any mood / light situation. So I did a little research and found about the posibility to trigger input on the Arduino with … Continue reading
Freeware OLED Pixel generation software “OLED Pixxler”
I started a little Arduino project involving an OLED (SSD1306) display using the u8glib library. I faced the issue that I wanted a few custom pixel / bitmaps for the project and also wanted to propably animate the grafics… and … Continue reading
Arduino Mini CNC Machine
To be honest: in the beginning I had no idea that there is such a thing like CNC machines. CNC stands for “Computer Numerical Control” and there are a ton of different machines out there ranging from 3 up to … Continue reading
Interface a cheap OLED (SSD1306) from eBay with an Arduino
There are a couple of cheap OLED displays available on eBay and I really struggled to get them to work with the Arduino. Some of them have the manufacturer “Heltec” printed on the circuitboard and most of them
C++ Template Arduino investigation
I tried to simplify and refactor some of my code for a new Arduino project lastly and came up with some interessting programming concepts in C/C++ I never heard of before my Arduino adventures. The Problem At first I wanted … Continue reading
