Parallel parking in congested urban areas has always been a challenge—and that’s where Solspot comes in. This blog post is a full walkthrough of how I designed and built a solar-powered smart vehicle prototype with 360° wheels, controlled wirelessly ...
To connect an MQ135 gas sensor with other sensors to your microcontroller (e.g., STM32, Arduino, ESP32), you essentially build a multi-sensor system where each sensor's signal is read through different GPIO or ADC channels. The MQ135 is an analog gas...
A Watchdog (or Watchdog Timer, WDT) is a critical hardware or software mechanism designed to detect and recover from system crashes or freezes in embedded systems (e.g., microcontrollers like STM32, Arduino, or ESP32). It acts as a "safety net" by re...
There are several common methods to connect Arduino boards to WiFi modules. Here are the most popular approaches: 1. Using ESP8266/ESP32 as WiFi Co-Processor Common Modules: ESP-01 (ESP8266) ESP-12E/F (NodeMCU) ESP32-WROOM Connection Methods: A....
In a world driven by smart technology, real-time data monitoring has become essential — not just in industrial systems, but even in basic IoT applications like temperature sensing. This post shows you how to build a complete IoT data pipeline using: ...
Multithreading enables microcontrollers to handle concurrent tasks efficiently. Here are the primary implementation approaches: 1. Real-Time Operating Systems (RTOS) Popular RTOS Options RTOSLicenseKey FeaturesBest For FreeRTOSMITLightweight, ...
Over the past few months, I’ve been diving into small IoT projects as a cool hobby. With each project, I kept running into something called MQTT — this mysterious protocol that everyone seemed to be using to connect devices here and there. I tried it...

I recently got an ESP32-wroom-32d chip working with Arduino IDE on my Macbook Air M2 (2022). I ended up going down some dead ends based on old documentation online, so I’m documenting how this worked for me in January 2025 in case it’s useful! The im...
