It has been a while sins I made a module for my homebridge, now I wanted to see if I could make a door lock. First I needed a door lock so I found this one. You can also use a door lock opener like this one. For those who haven’t read my previous post, […]
Raspberry Pi – Zero W
Last year, when the Raspberry Pi Foundation announced the Pi Zero and that it would cost only €5,50 and come free with an upcoming issue of the Pi themed magazine MagPi, everyone went crazy for it. Even over a year later, the Zeros are hard to purchase due to demand. To achieve this price point […]
Arduino – Connecting a ESP8266-1
The main aim of this project is to control home appliance over the internet. I was trying to make an project for the Apple HomeBridge and I decided to keep the Arduino Nano and add a ESP8266-1 module. It works by connecting the Arduino to the internet through esp8266 WiFi module. This setup is a […]
Arduino – Air Pollution Monitoring System
In this project I’m making a Air Pollution Monitoring System in which we will monitor the Air Quality over a webserver using internet and will trigger a alarm when the air quality goes down beyond a certain level, means when there are sufficient amount of harmful gases are present in the air like CO2, smoke, […]
Arduino – A4988 Stepper Driver
For a upcoming project I need to control a Nema 17 Stepper. Therefore I need to use a stepper driver In a previous blog I described the DVR8825 Now its time to look at the A4988 Stepper Driver. A4988 The A4988 is a microstepping driver for controlling bipolar stepper motors which has built-in translator for […]
