Have you ever wanted to create a project that involved non-contact detection, such as detecting the closing of a door, counting the number of revolutions of a wheel, or creating a speedometer? Then this blog about the Hall effect sensor is for you. This project uses a Hall effect sensor to detect the presence of […]

This is one of my bucket list the CNC – Mini Laser Engraver. You probably have seen one come by at one point. This is an blog on how I made an Arduino CNC – Mini Laser Engraver for wood and Thin paper, Just using some old DVD drive stepper mechanism and a 250mW laser.

Through some researches I did online on how to minimize components use, I stumbled with using an ATTiny13A chip to be used in the project. And through some more researching, I decided to have my new project done using the ATTiny13 Chip. ATTiny13 Chip I bought these chips from Ali-Express. First I need to study

The I²C bus communication is one out of three possible communication protocols, the ESP8266 is able to communicate with other devices like OLED displays, barometric pressure sensors and so on. The two other communication protocols are SPI and UART. I²C stands for Inter-Integrated Circuit was invented 1982 by Philips Semiconductor (A Dutch company), now NXP
I have only started electronics as a hobby and it has been a great learning resource for me so I am far from any type of expert. But I like to share my knowledge. I wanted to change the logo on my OLED display. It took me days to work it out thanks to very

I need a remote that I can program and that will work on batteries for a long time. So I was thinking of using a ATTINY with a way that enables me to send the information over the air. And when it comes down to having inexpensive yet reliable 2-way RF solutions, no one does
