This Arduino project is a simple and fun project you can build in 10-15 minutes. The result of this make will be an Arduino audio player that plays “.wav” files. It consists of a speaker, a simple transistor acting as an amplifier, and a micro-SD card adapter with a micro-SD card in it where the .wav […]

In this tutorial, we will make the communication between the Arduino and Processing. We will make the communication in both the ways, from the Arduino to Processing and from Processing to the Arduino. We will change the color of the serial window in the Processing IDE through the potentiometer value sent from the Arduino IDE.

As a simple first Arduino experiment I interfaced a two line LCD (a Displaytech 162B) and an LM35DZ to make a simple Min/Max thermometer. Step 1 – Interfacing the Temperature Sensor This is really very simple. The LM35DZ has three pins, +5V, ground and a variable voltage output to indicate the temperature. I plugged it

As thefts are increasing day by day security is becoming a major concern nowadays. In this project we will make a digital door lock system with keypad using Arduino Uno. It will open your door only when the right password is entered and it will start beeping when a wrong password is entered. Components Required 4×4

Today we are going to make an IoT WiFi data logger using Arduino, ESP8266 WiFi module and DHT22 temperature humidity sensor. Arduino is reading temperature and humidity sensed by DHT22 and sending it to an internet server using the ESP8266 WiFi module. Here we are using ThingSpeak as the internet server. ThingSpeak is an open source IoT application

In this tutorial we are going to make a weather station that will tell us temperature, humidity and heat index of a particular location. It will show these values in a web browser. You can monitor these data by entering the IP address in a mobile, computer or any other device which supports a web browser. This project

Hello! This is a quick, intermediate Arduino project that takes a temperature reading from a TMP36 , reads it onto an LCD screen and gives an “Analog” readout on a Neopixel stick that changes color and number of lights lit every 10 degrees Fahrenheit. It’s easily customizable as NeoPixels can be coded in many ways

Today we are going to Measure the Weight by interfacing Load Cell and HX711 Weight Sensor with Arduino. We have seen weight machines at many shops, where machine displays the weight just by placing any item on the weighing platform. So here we are building the same Weighing machine by using Arduino and Load cells,

FlashProg is USB base flash memory programmer to work with 3.3V serial flash memory devices. This programmer is specifically design to read, program and configure 25x series, serial flash memory devices which are commonly used to store BIOS in PC mainboards. Originally we design this project to read and program BIOS of Foxconn G31MXP mainboard.

ESP8266 + DS18B20 Temperature sensor sends data to Thingspeak.com Its been a while i was searching for a cheap wifi module and with the help of smart-prototyping.com, i was able to get a module almost less than USD 5. To connect the module to breadboard for prototyping, i made a small jig to interconnect with
