Note: updated with new firmware, a schematic and a tips for a programmer. A couple of years I embarked on my own home automation project. It started off by building a server controlled 433 MHz transmitter build with an Arduino to switch lots of cheap PT2262 based remote switches. Later I added an Arduino based […]

Some time ago, I tried to make an “Instructables Hit Counter” using the Instructables API, and an Arduino Uno with a wired network shield. However, with the limited RAM of the Arduino Uno, I was unable to get the system to work. A while ago, I noticed a similar project done by diytronics using a NodeMCU. This was just

WiFi has become an integral part of our life and daily billions of people use WiFi as a method to access the internet. But the range of WiFi is limited, unlike a cellular connection. A normal WiFi router usually has a range of about a 100m in clear sight and about 20m to 50m without clear

The main idea was to read in 13.56 MHz RFID (tags / tokes / stickers / wristbands / cards) by a magic box and post the RFID UID to a local database by WiFi network. This instructable builds the base of the whole system – the first working RFID reader on ESP8266 WiFi SoC. (many
I quickly was able to appeal to the network card via a 8-bit data bus. The connectivity of the network card and thus the RTL8019AS chip via two 8-bit ports of the processor and… Electronics Projects, Embedded RTL8019AS Web Server Project ATMega103 “avr project, microcontroller projects, “ I quickly was able to appeal to the network card via a

Introduction Overview PowerManager is a remote power management system that can be controlled through a web browser on a local area network (LAN). Devices plugged into PowerManager’s outlets can be turned on or off with the click of a button on a webpage. PowerManager runs on an ATMEGA644 microcontroller and an ENC28J60 Ethernet controller. Together,

Introduction For our ECE 476 Final Project, we have built an intelligent, wearable pedometer. This wireless pedometer can calculate many useful statistics such as the number of steps a user has taken, the distance and the speed the person has walked/run, as well as the number of calories the person has burned. This information is

Introduction Perusing through the impressive list of past projects, we decided to make our final project a combination of two technologies—wireless technology and the MP3 player. Specifically, we decided to create an MP3 player that broadcasted the songs to an FM dial. We call this the “MP3 Radio.” To accomplish this, we used an ATMEL
