Teach the Particle Photon to Text In 5 Minutes

Have an Internet of Things project idea that needs text capabilities? Let me show you have easy it is to teach your Particle Photon how to text. In fact it’s so easy it only takes a few minutes.

State machine with Arduino

Many systems can be described with state diagram. Therefore they can be implemented with so called State machine code with system delay. System delay can be used in other project too, but I will show you how it works on automation processes example, which State machine is.

Software PWM for controlling LEDs

LED’s brightness can be controlled with Pulse Width Modulation or PWM. Arduino only have so many PWM ports. Did you ever wonder how to control the LED on any Arduino Pin? Here is how you can make it.

Creating A Simple Relay Board Using Eagle

Here we just do a really simple relay board with two terminal blocks and an omron relay. Below you will see the schematic. I chose the components from the Eagle library which can be accessed from the add component button in the left hand tool bar.

LDR light sensor tutorial

Recently I received a question from a good friend of mine. He wanted to automate blinds on his office window and he wondered how he can measure or detect light. I told him that the simplest solution would be using LDR resistor.

Attendance Logger

I made this project long time ago. It was build as proof of concept while working for local tech company. Since then I have used it to track my working hours on my personal projects. Here is how you can make one.
