Smart Phone Controlled Arduino Mood Light with Alarm

I recently purchased the NeoPixel LED strip and was quite impressed by the way it works. The tiny LED’s have an inbuilt driver IC which helps us to control each LED individually and can produce a wide spectrum of colors. Being a garish person who is obsessed with colours I really loved watching these tiny LED’s changing colors so I decided to build something on my own and leave it coloring my bedroom during night times.

IoT Based Patient Monitoring System using ESP8266 and Arduino

Here in this project, we will make an IoT based Health Monitoring System which records the patient heart beat rate and body temperature and also send an email/SMS alert whenever those readings goes beyond critical values. Pulse rate and body temperature readings are recorded over ThingSpeak and Google sheets so that patient health can be monitored from anywhere in the world over internet. A panic will also be attached so that patient can press it on emergency to send email/sms to their relatives.

Arduino Based Guitar Tuner

Hi guys, during the last few weeks, I’ve been working on reconnecting with my love for the guitar. Playing the box guitar was how I relax few years back before the saxophone took over. Going back to the guitar, after 3 years of rarely strumming a chord, I discovered amongst other things that I no longer knew how each of the string should sound, to put it in my friend’s words, “My hearing was no longer tuned” and as a result of this, I was not able to tune the guitar without the aid of a keyboard or a mobile app which I later downloaded. The weeks went by till few days ago when the maker in me became motivated and I decided to build an Arduino based Guitar Tuner. In today’s tutorial, I will be sharing how to build your own DIY Arduino Guitar Tuner.

Analog Speedometer Using Arduino and IR Sensor

Analog Speedometer Using Arduino and IR Sensor

Measuring the speed/rpm of a Vehicle or a motor has always been a fascinating project to try. In this project, we are going to build a Analog Speedometer using the Arduino. We will use IR Sensor module to measure the speed. There are other ways/sensors for this, like hall sensor to measure speed, but using an IR sensor is easy because IR sensor module is very common device and we can get it easily from the market and also it can be used on any type of motor/Vehicle.

Self Balancing Robot using Arduino

Self Balancing Robot using Arduino

Once I started building the self balancing robot, I realized that this bot is a bit of a challenge to build. There are so many options to select from and hence the confusions start right form selecting the motors and remains till tuning PID values. And there are so many things to consider like type of battery, position of battery, wheel grip, type of motor driver, maintaining the CoG (Centre of gravity) and much more.

But let me break it to you, once you build it you will agree that it’s not as hard as it sounds to be. So let’s face it, in this tutorial I will document my experience in building the self balancing robot. You might be an absolute beginner who is just getting started or might have landed up here after a long frustration of not getting your bot to work. This place aims to be your final destination.

I think my robot dog walking service just needs a little more tuning.

Controlling Arduino with Raspberry Pi using pyFirmata

We use PyFirmata firmware to give commands to Arduino using Raspberry Pi python script. PyFirmata is basically a prebuilt library package of python program which can be installed in Arduino to allow serial communication between a python script on any computer and an Arduino. This python package can give access to read and write any pin on the Arduino. So here we will run python program on Arduino using Raspberry pi.

So in this tutorial we will take advantage of this library and will use this in our Arduino board to control Arduino using Raspberry Pi.

Programming STM32F103C8 Board using USB Port

Programming STM32F103C8 Board using USB Port

In our previous tutorial we learnt the basics of the STM32 Development Board and also programmed it to blink an LED. But there was one huge drawback with it. In order to program the Board we utilised a FTDI programmer module and also had to toggle the boot 0 jumper between and 1 position while uploading and testing a code, which is surely a daunting task. Also the mini-USB port on the Development board was left totally unused. The reason for doing that is, when the STM32 development board is purchased it does not come with an Arduino ready boot loader and hence the board will not be discovered by your computer when connected through the USB.

Arduino Based Real-Time Oscilloscope

Today I will be demonstrating how to use the Arduino and a software, which will be developed with my favourite programming language Python, to build a low cost, 4-channel Arduino oscilloscope capable of performing the tasks for which some of the cheap oscilloscope are deployed like the display of waveforms and determination of voltage levels for signals.
