Here is how engineers can design digital input modules with a parallel interface using industrial serialized digital inputs.

Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I document my learning in order to be able to inspire other people to make ...

Use Arduino to handle sensor input and relay control. Pi runs a Python Flask server with a simple UI to toggle GPIO pins via serial commands sent to the Arduino.

M5Stack StamPLC – An ESP32-S3-based PLC with opto-isolated inputs, relay ouputs, RS485, CAN Bus, and more “M5Stamp PLC Controller with M5StampS3” or just “M5Stack StamPLC” is a programmable logic ...

Here are some of the worst examples we've come across. Hopefully, you'll share some of your own experiences in the comments. We might even do a follow-up story based on those.

So I wanted to set an example for other athletes that age does not matter,' says MR Poovamma, Arjuna Awardee and the senior-most member of the Paris Olympics-bound Indian women's 4x400m relay team.

A simplified version simply needs a speaker, breadboard, inputs, and wires. The Arduino controller can be programmed to output any of the standard 12 musical notes associated with the input.

Multi-house Water Pump Control System -Working The optocouplers sense power supply availability and motor switch status in all the houses, interfacing with the Arduino Nano board and relay driver IC ...

Here, we are using a 4 relay module because we will only control four appliances. If you want to automate a different number of appliances, you can use a different relay module. There are many relay ...
