How to Set Out Pi Hole on Raspberry Pi

How to Set Out Pi Hole on Raspberry Pi Meta description: How to install Pi Hole on the raspberry pi, a guide for blocking ads and other trackers for all devices on your network Introduction One of the most popular raspberry pi projects, Pi-hole blocks ads and trackers for all of the devices on your network Overview The Pi-hole blocks ads and trackers from devices connected to your network by acting as a sinkhole for the Domain Name System, or DNS. This is a critically important service that enables the conversion of domain names to IP addresses and is used by all computing devices connected to the internet. Requirements Things you will need to set this project up include: • Raspberry Pi (any model with network connectivity should work, Pi 3, 4, and 5 all work well, and are popular choices for this project, even Pi Zero W works for a home network) • Micro sd card (At least 16 GB is needed, but can be anything beyond that) with raspberry pi os installed • Power supply for your raspberry ...

Arduino Vs ESP32 Vs Raspberry Pi: Which one should you choose? Review

Arduino Vs ESP32 Vs Raspberry Pi: Which one should you choose? Review Meta description: Confused about the differences between Arduino, ESP32 and Raspberry Pi? In this blog, we compare the key differences, use cases, and which one to buy. Introduction If you are new to the world of electronics and IoT, you might be faced with the dilemma which is Arduino, ESP32, or Raspberry Pi? All of these are completely different things, despite the fact that they are often used together, but not at the same time. In this blog, we will review what are the main differences between these platforms and which one is better for your electronics project. The short answer is: Arduino – is great for simple and straight forward electronics projects (sensors, relays, etc.) which do not require Wi-Fi or any other advanced features; ESP32 – is Wi-Fi-enabled microcontroller, best for IoT projects; Raspberry Pi – is a full-scale computer, capable of running complex tasks and applications. Overview of Arduino, ESP...

Arduino HC-SR04 Ultrasonic Sensor Tutorial. Measure Distance with Code & Wiring Diagram

Arduino HC-SR04 Ultrasonic Sensor Tutorial: Measure Distance with Code & Wiring Diagram Meta description: Learn how to wire and program an HC-SR04 ultrasonic sensor with Arduino to measure distance in centimeters and inches — full code and troubleshooting included. Introduction The HC-SR04 ultrasonic sensor is one of the most widely used components in beginner Arduino projects. It measures distance by sending out a sound wave and timing how long it takes to bounce back — the same basic principle used by bats and sonar. In this tutorial, you'll learn how to wire the HC-SR04 to an Arduino, program it to measure distance, and display accurate readings in both centimeters and inches using the Serial Monitor. What This Project Does You'll build a simple distance-measuring circuit where the Arduino triggers the HC-SR04 to send an ultrasonic pulse, measures the time ...

ESP32 Web Server | Display DHT22 Temperature & Humidity in Your Browser

ESP32 Web Server: Display DHT22 Temperature & Humidity in Your Browser Meta description: Turn your ESP32 into a local web server that displays live DHT22 temperature and humidity readings in any browser on your network — full code included. Introduction If you've already wired up a DHT22 sensor to your ESP32 (see our ESP32 DHT22 tutorial), the next logical step is getting rid of the Serial Monitor and viewing your readings on an actual web page — from your phone, laptop, or any device on your network. In this tutorial, you'll turn your ESP32 into a self-hosted web server that displays live temperature and humidity data from the DHT22 sensor directly in your browser. What This Project Does The ESP32 connects to your Wi-Fi network, hosts a simple web page, and refreshes temperature and humidity readings from the DHT22 sensor automatically. No inte...

ESP32 DHT22 Temperature & Humidity Sensor Tutorial

ESP32 DHT22 Temperature & Humidity Sensor Tutorial (With Code & Wiring Diagram) Meta description: Learn how to connect a DHT22 sensor to an ESP32 and read temperature and humidity data with this complete wiring diagram, code, and troubleshooting guide. Introduction The DHT22 is one of the most popular sensors for measuring temperature and humidity in DIY electronics and IoT projects. Paired with an ESP32 — a microcontroller with built-in Wi-Fi and Bluetooth — it's a great starting point for weather stations, home automation systems, or any project that needs environmental data. This guide walks through wiring the DHT22 to an ESP32, writing the code to read sensor data, and displaying temperature and humidity readings on the Serial Monitor. What This Project Does You'll build a simple circuit where the ESP32 reads temperature (in Celsius and F...
