Light Saber Build Part 2
This is the continuation of the Light Saber Build Part 1. You can check the previous post to see where I am up to. Just […]
Light Saber build part 1
Today is May Day, so I though to prepare and finish off my Light Saber build that had been sitting in my shelf for quite […]
3 Step to use External Interrupt on ESP8266
I was in the middle of replicating my 433 MHz remote control using Arduino. The receiver circuit is quite simple and it is using Arduino […]
Connecting IoT Sensors data to Node-RED
This is the continuation of the Temperature sensor project in the previous post. The concept is to allow the data from sensors (temperature, motion) can […]
Realtime Clock with 18F2550
I am trying to make use of the previous circuit on connecting LED display to 18F2550, and combining this with Real time clock module DS3231. […]
Connecting ESP8266 to P10 Display and displaying data from webserver
The concept is to have the ESP8266 driving the P10 display by reading the data from the webserver, this will ensure that the data can […]
Adding Piezzo speaker to Analog Output
In my previous post, I was using my LED matrix circuit to display the Fibonacci clock. So I am a bit stretched on the I/O […]
LED Matrix Fibonacci Clock
I was inspired by all the Fibonacci clock out there, so I decided to design one my own. I am using the same LED Matrix […]
Bluetooth Amplifier Review
Finally all my Bluetooth Amplifier arrived. So naturally I started to tinker with them. Started with the following “Bluetooth 4.0 Digital 2.1 Class D HIFI […]
Arduino Binary Clock
This post is build on top of the LED matrix in the earlier post. I always wanted to build an Binary clock, and since I […]
Simple Frankenbot with lights and sound effect
I was inspired by the cute Frankenbot papercraft from Instructables, so I thought why not make it truly alive by giving it some blinking lights […]
IoT Gas Sensor with ESP8266
I had been wanting to get the gas sensor working with my ESP8266 as an additional item on the IoT list. So similar to the […]
Arduino Dice simulator
I was looking at my kids playing snake and ladder tonight, and came an idea in my mind “why don’t I make a dice simulator?”. […]
RFID enabled tag
This RFID enabled tag tutorial show a simple RFID circuit that connects to Arduino. The circuit will detect the RFID card and play a simple […]
The simplest Mario speaker song circuit
The other day I stumble upon a simple circuit to create a speaker song. So naturally I try it out and it seems to be […]
Disco Light using LED Strip
My Daughter had a disco night to attend, so what could be better than equipped her with and LED Strip which will flash through the […]
BTCmarket ticker using ESP8266
With the recent fall of Bitcoin and other crypto currency and my continue interest in learning more about Arduino, after reading several other instruction of […]
IoT Motion Sensor with light
This is the extension of the earlier post IoT Temperature Sensor with ESP8266. The extension is to additional IoT Motion Sensor with light. Here are […]
