WordPress comes with a built-in feature that allows you to undo changes and go back to a previous version of a post. This feature is called Post Revisions or simply Revisions. But suppose your post revisions are too high from…
Introduction In this arduino clock project we are displaying time on 7 segment tube display. Unlike other posts where I had used lcd display. Tube display board uses TM1637 chip. Parts required For this project we need 3 important parts…
Introduction to OV7670 camera module The OV7670 image sensor is a small size, low voltage, single-chip VGA camera and CMOS image processor for all functions. It provides full-frame, sub-sampled or windowed 8-bit images in various formats, controlled through the Serial…
In this post we will connect the LCD to GPIO (General Purpose Input Output) pins of PI to display characters on it. We will write a program in PYTHON to send the appropriate commands to the LCD through GPIO and…
In this post we will HACK ATX power supply to use it as a bench top power supply which can be used for different electronics projects. Parts needed An ATX Power supply. You can salvage from your old desktop computer.…
Introduction In the previous part we have seen how to configure Azure for IOTHub. In this post we will cover setting up the Raspberry Pi and connecting it to the sensor and sending the data to Azure IOTHub. For more…
Introduction In this part we will cover how to configure Azure IOT hub and make it ready for using it with Raspberry Pi or ESP8266 boards. Things that you Need An ESP8266 Dev board or Raspberry Pi 2 or 3…
In this project we will learn to measure Humidity and temperature using DHT22 and Arduino. There are 2 version of the sensor DHT11 and DHT22. DHT22 sensor is more expensive and obviously has better performance and accuracy. Its temperature measure…
Below is the circuit idea for pocket size FM receiver using RF transistors. The circuit works off a small 4.5 volt battery or 5v USB. The heart of the circuit is the two RF transistors T1 and T2 to detect…
Making Raspberry pi as print server will help you in making your printer wireless. What you need ? Raspberry pi USB wireless dongle. USB Printer I am assuming that you have already setup raspberry pi with suitable OS. Make sure…
