In this ESP32 tutorial, I have explained how to connect the TTP223 touch sensor with ESP32 to control relays. We will discuss what changes you must make in the circuit and source code to add to control relays with the TTP223 touch switch. So after going...
Since Telegram is a cross-platform cloud-based messaging service compatible with iOS and Android, I decided to create a Telegram bot to manage my security system on disparate devices easily. In Telegram, it is effortless to create bots with a command...
Story When people think about asset trackers, typically they think about tracking things that should move: planes, trains, and automobiles. What we don't think about as frequently is keeping track of things that shouldn't move: statues,...

In the beginning there was the passion for technology. I decided to start a blog and write about the things I've built. I was more into high voltage, physics and various experiments, cool, but with little or zero use to those around me. Then I decided...
The general goal is to make a 'kit' of reusable components for wearables.Bluetooth BLE is the standard for communications. WiFi, etc. require too much power and anyone with a wearable likely has an Android or iOS phone. All wired connections are USB...

[UPDATE] Now using MKR1000 to control the UNplug unitI replaced the Particle Core with an Arduino MK1000 for several reasons:The pricing policy for a production run with more than 25 units is locking the user into a monthly subscription to access to...

So for me this all started with just wanting my porch lights to automatically turn on at dusk and off at dawn. A day/night sensor ~should~ be the easy solution, but neither fixture would accommodate one, and given that I rent my house, I couldn't just...
How it worksIn a normal data flow, when we have the physical STK500 programmer board, the microcontroller code (firmware) produced by the compiler is sent to STK500 software. The STK500 software will produce ISP commands for the STK500 board, and will...
When the Raspberry Pi Zero was announced, a significant chunk of the hacker world dismissed it for having the same fatal flaw as the other Pis: only one USB host port for high speed I/O.Network connectivity is a major reason that people base projects...
The Omzlo One is a wired IoT Arduino-compatible platform with interesting features supporting home automation and sensors: You can use an Ethernet cable — or just 4 plain wires — to connect your Omzlo One devices to one another in a chain that can reach...
If you need a very-high throughput or a multithreaded web server to host data for everyone on the web, look at Apache (with CGI), NGINX or https://www.gnu.org/software/libmicrohttpd/ However they are limited by the CGI's basic inability to preserve a...
