Someone contacted me for a hobby project to monitor his children’s room and after the project, I decided to dabble a little into a baby monitoring device. At least, I came out with something useful although the device is not yet complete but it will surely serve.
In this post/tutorial, We will be controlling two Servo motors attached to an Arduino board from Raspberry Pi (RPi) using Serial Communication. I earlier made a post on Arduino – Rpi Communication using Serial communication, but it was just to send data from the Arduino to Rpi.
I decided to play around again. Java was the first programming language that caught my interest, and when it came to embedded programming. Python provided lesser lines of codes but I still feel that my bae Java will one day come knocking.
Some months ago, I made a post on Home Automation system and Security System. It have been a while and the project is almost 98% complete but that won’t stop me from posting the update.
This tutorial is about interfacing to a 4×4 keypad to an Arduino board, save passkey, retrieve passkey and finally unlock something (something like access control). It is an upgrade to the first post I made some months back on Security access control.
This will be my first post in this new month but before I forget: Happy new month to my lovely readers and followers. This post/tutorial is on how to create a simple battery level indicator with LCD screen and Arduino uno. This setup have been ON in my home for the past few days without
I had this 434mhz transmitter and receiver modules lying around idle so I decided to put them to good use. For learning sake, RF (Radio frequency) suppose to be referred to as radio frequency waves are part of the electromagnetic spectrum.
The day was going down and becoming boring so I decided to see out with at least one post. Assuming you are a home gardener and very busy, maybe low on budget. I think this is for you. This post is all about a home made soil moisture level indicator with an LED. Since, we
Good day, today I decided to put some old push buttons I rescued from an old project to good use. Today, I will be going into using interrupt in Arduino. Trust me, it is a very cool practice to employ.
I savaged some lithium battery cells from my old laptop battery and a battery pack that almost burnt down my home and started thinking what I will do with them but they all need to be charged. This is where TP4058 Micro USB Charger came to the rescue.
