Send SMS with SIM900D in Proteus ISIS

Hello friends, hope you all are fine and having fun with your lives. Today, I am going to share a new exciting post on Send SMS with SIM900D in Proteus ISIS. In my previous post, I have shared the new GSM Library for Proteus, which is the first ever designed library for Proteus, and I am quite excited while sharing its features. So, today, we will use this GSM Lirbary for Proteus and we are gonna send sms w ...

How to Select a Resistor

When I was working on the next version of Common Parts Library, I realized that it would be helpful to explain why you might pick one type of passive component over another. We started off by writing “How to Select a Capacitor” last month, and are following it up with a close look at resistors this month. In this blog, we will explain all the different types of resistors, their merits and demerits, and popu ...

Add SSL Certificates To MKR1000

Cannot connect to your favourite https site with your MKR1000? Follow this guide to install SSL certificate in a easy way using the GUI. Things used in this project Story Please note that with the IDE starting from version 1.6.10 the certificate uploader (and the firmware updater) is direct inside the IDE without the need to launch any external executable. Check this out https://www.arduino.cc/en/Tutorial/F ...

How To Select a Capacitor

When I was working on the capacitors section for the next version of Common Parts Library, I realized that it would be helpful to explain why one might pick one capacitor type over another. This information is important because there are a lot of factors (temperature characteristics, package, etc.) which might make a type of capacitor (electrolytic or ceramic) better than others for your project. In this bl ...

DC-DC Buck Converter Circuit – How to Step Down DC Voltage

In this project we are going to make a Buck Converter Circuit using Arduino and N-Channel MOSFET with a maximum current capacity of 6 amps. We are going to step down 12v DC to any value between 0 and 10v DC. We can control the output voltage value by rotating the potentiometer. A buck converter is a DC to DC converter, which steps down DC voltage. It is just like a transformer with one difference; whereas t ...

Arduino DC Motor Speed and Direction Control using Relays and MOSFET

In this project we control direction and speed of a 24v high current motor using Arduino and two relays. No power switches are needed for this circuit, just two push buttons and in Potentiometer to control the direction and speed of DC Motor. One push button will rotate motor clockwise and other will rotate it counter clockwise. One n-channel MOSFET is required to control speed of motor. Relays are used to ...

Arduino RFID Keycard Access

Use the PN532 NFC available on the anduinoWiFi shield to create an RFID keycard building access system. Motivation Keys are so last century, and now that you can easily replicate a physical key just by snagging a photo it might be time to upgrade our locks! This project outlines a framework for you to get started implementing your own unique locking mechanisms. In this project you'll authenticate individual ...

Get Connected! WiFi Registration Using AP Mode!

Motivation So I've just spent an "all nighter" working on this new IoT device that's going to change the world. The sun comes up, and I'm off to demo the device and pitch to my friends for some seed capital and soul crushing criticism. I get to their house, turn the device on, it won't connect... quickly I realize the device is still flashed with my home WiFi credentials. Time to quickly edit my code, refla ...

Control accurate incremental voltage steps with a rotary encoder

Experimenting with an HF oscillator, I needed to control the varactor diode voltage in precise increments over a 2V-10V range. A buffered potentiometer was the obvious choice, and connecting two pots in series to give coarse/fine control (or using a multiturn pot) would offer improved control over the varactor voltage. However, this approach still didn't allow me to generate uniform increments and decrement ...
