ESP8266 Deep sleep mode
I always wanted to learn about the deep sleep mode in ESP8266. So I stumble across a few post in the internet, and comparing various […]
Publish MQTT using Javascript
Continuation to the previous post about the Automatic IoT Gate control, once we have connected the ESP8266 gate Opener to listen to the message broker, […]
Connecting the IoT Remote Gate Opener to MQTT
Now that we have a reasonable understanding about MQTT, we can connect our IoT Gate Remote from the previous post to the MQTT broker. The […]
IoT Remote Gate Opener
I am helping my brother to make a remote Gate opener. He have a remote that can open the gate, but being in this day […]
Connecting ESP8266 to MQTT broker
So what is MQTT, according to mqtt.org, it is a connectivity protocol used to connect machine to machine, used for Internet of Things (IoT). It […]
ESP8266 Secure AP mode
Quite often we take shortcut to make things simple. That that sometimes will come and bite you back. To make sure you always consider security […]
Arduino LED Matrix “Game of Life”
I was reading a post about someone making a Thanos Gauntlet and simulating wiping off half of the population randomly. So I thought about the […]
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 […]
