Hello! This time I'll show how I used an Arduino to control a relay module with eight channels.
Arduino in offers several advantages such as:
- Open source;
- Easy programming;
- You can assemble your own board;
- Is supported on various forums on the Internet;
- Has several "shields" (facilitates the use of it with sensors, for example.)
- Among others.
The idea I had was to create a simple programmable hardware. Where only would create a different software for each application.
Just as our computer. What we do (generally) is add a software The hardware remains the same.
We can control larger loads within the limits of current and voltage relays. For example, connecting a ventilator, an appliance, among others.
Step 1: Materials
Below the list of materials:
- Arduino board;
- Sensor shield;
- 8-channel relay module;
- 11.1V battery
