Good day folks, it have really been awhile so in this post we will work on a Fingerprint Attendance system with Raspberry Pi with GUI. I must confess the Android version is much more simpler. So lets not waste much time with pleasantries and get to work.
In this post, we are going to use/connect a LDR to Raspberry pi. This can be useful in many applications. An LDR is a component that has a (variable) resistance that changes with the light intensity that falls upon it. This allows them to be used in light sensing circuits.
In this post, I will show you how to make your own RF (radio frequency) home automated system. I just made a dummy prototype with cheap components which you can easily source. Although I have posted something like these before here, this is more elaborate and useful.
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
