In my last blog, I explained how CAN and OBD-II let a car’s ECUs talk with each other and how a scan tool listens in. What I skipped over on purpose is the tiny chip that makes any of that possible: the CAN transceiver. Without it, your microcontroller is basically shouting into a wall. This is what a CAN transceiver looks like: CAN Bus transceiver Communication Module Based on SN65HVD230 The Translator Your ESP32 has a CAN controller built in, on ESP32 it’s called TWAI. Tha

When you press the accelerator, how does your dashboard know the speed? How does the engine communicate with the transmission? How does a diagnostic scanner read information from your car? What is ECU? An ECU (Electronic Control Unit) is essentially a small computer responsible for a particular function inside a vehicle. One ECU may manage the engine, another the brakes, another the transmission, while others handle airbags, steering, temperature and more. These ECUs don’t wo

If you have read my previous blog, “Blockchain Explorers: What’s Actually Happening On-Chain,” you might remember that while exploring a block, we came across a field called Merkle Root. At first, it looks like just another long string of letters and numbers in the block details. What is this hash actually telling us? We already know that a block can contain hundreds or thousands of transactions. So, how does the blockchain keep track of all those transactions in a way that i

In the previous blog, we discussed the basics of SCADA, including its importance and architectural framework. This blog shifts the focus to key components such as Remote Terminal Units (RTUs), Human-Machine Interfaces (HMIs), and Intelligent devices. Additionally, we’ll examine the roles of data loggers and Intelligent Electronic Devices (IEDs) in SCADA and IoT systems. What Exactly is an RTU? Often referred to as remote telemetry or telecontrol units , these devices excel in

Supervisory Control and Data Acquisition (SCADA) is a sophisticated system designed to provide comprehensive monitoring, control, and management of industrial processes. It serves as the central nervous system of industrial operations, collecting and analyzing data from various field devices and enabling real-time decision-making. The system consists of both software and hardware components and enables remote and on-site gathering of data from the industrial equipment. SCADA

Hey everyone! It’s time for another topic into the world of IoT!Today we’re gonna learn about CoAP and MQTT. Don’t worry if these sounds like alphabet soup right now, I promise it’ll all make sense soon! So, this is actually part 4 of our IoT series (I know, right? We’re ofc super regular!). If you’ve been keeping up, you already know the basics of IoT , all about sensors and actuators , and the different ways IoT gadgets connect to the internet. If you missed those, no stres

Welcome back to our continuing exploration of IoT! In our previous sessions, we’ve covered the fundamentals of IoT, including its core concepts, digitization, and various architectures. We’ve also seen the basics of sensors and actuators, which form the backbone of IoT systems . Today, we’re shifting our focus to IoT access technologies. These are the critical communication methods and protocols that enable IoT devices to connect, interact, and share data effectively. In thi

In the previous blog, “ The Connected World: IoT ,” we explored IoT, digitization, various structures, and M2M architecture. Today, we’ll see sensors, actuators, smart networks, and key protocols driving IoT innovation. Sensors: Sense Sensors, the digital counterparts to human senses, serve as the primary interface between the physical and digital worlds. These sophisticated transducers convert a wide spectrum of environmental stimuli into precise digital signals, vastly outp

Ever wondered if your thermostat could actually talk with your smart lights about the perfect ambiance for movie night? That’s the cool reality of the Internet of Things (IoT). IoT links up everyday objects like toaster, lights, speaker, fan, vehicles etc, so they can swap data and make our routines smoother and smarter. But let’s get technical without the yawns. IoT is a network of physical objects embedded with electronics, software, and sensors. These smart devices collect

In this blog, I’ll guide you through the steps to set up your Raspberry Pi, making it an easy and interesting walk through. The Raspberry Pi Zero W is a tiny yet powerful single-board computer with built-in Wi-Fi and Bluetooth capabilities. The “W” in its name stands for wireless, highlighting its ability to connect to networks and devices without the need for additional hardware. The Raspberry Pi Zero W shares the same core features and functionality as other Raspberry Pi
