For this week I set out to make a board that will show realtime MBTA bus arrival times using the ESP8266 wifi module and a LCD. Seemed doable. People of the internet have been excited about the ESP8266 lately. Here is a snapshot of google trends for searches for esp8266 vs couple of other arduino …
This project is a dust detector that use the GP2Y1010AU0F sensor. Attached you can also find the GP2Y1010AU0F sensor library for AVR Atmega. GP2Y1010AU0F is a dust sensor by optical sensing system. An infrared emitting diode (IRED) and an phototransistor are diagonally arranged into this device. It detects the reflected light of dust in air. Especially, it is …

Ultraviolet (UV) is an electromagnetic radiation with a wavelength from 10 nm to 400 nm. The ML8511 is an ultraviolet sensor that output an analog signal correlated to the amount of UV light detected. By datasheet the sensor detects wavelength from 280nm to 560nm. Here I’ve implemented a driver for AVR Atmega, portable to other microcontrollers, that correlates the sensor output …
Controlling numeric LCD isn’t so tricky as it may look like. O course you can find numbers of LCD libraries. One of more universal you can find in AVRLIB library for WinAVR AVR GCC compiler. Main disadvantage of such universal libraries that they compile all functions even if you don’t want them. This way huge …

AVR SED1520 Library This is a C-library for avr-gcc/avr-libc to access SED1520-based graphics-LCDs. The modules used to develop the library only support “write to LCD”, read-modify- write on the display RAM is not possible. So this Library uses a “framebuffer” which holds the display-content in the AVR’s SRAM. For a 122*32 pixel display around 500 …

lcdmenu1 is a simple and small lcd menu builder for AVR Atmega. It works with only 4 buttons (up, down, right, left), additional buttons can be added. It can also store values to eeprom User can use button up and down to list menu categories, right and left to browse child and parent. If an item is selected, …

The project TiDiGino We developed a new GSM remote control called TiDiGino. The name recalls the initials (TDGxx) of our previous GSM remote control and is also based on the Arduino project. All the details of this circuit can be found below, but no the sketch, because this is your assignment. The contestYou have to write the firmware for this project. The device must perform all the functions of the past …
Hey, I am a big fan of Instructables. I have consistently used it for the past 3 years and now its time for me to write one myself.Here we go. This instructable is for those who want to make some inanimate object tweet automatically. Like say for example you are building a robot and you want the …
