The ESP32 is a low-cost, low-power, 32-bit microcontroller family introduced in 2016 by the Chinese company Espressif. It is an open design, open-source-friendly family of microcontrollers which enable the construction and networking of network-based actuators and sensors. The GNU Compiler Collection including the toolchain is available as a free development tool. The ESP32 family has various … [Read more...]
How to Connect Bixby with ESP32 Arduino
Worldwide, there are a lot of Samsung Galaxy smartphone users and integrating ESP32/Arduino Bixby can help them easily automate their devices and homes within the Samsung ecosystem. The method we are describing to integrate does not require a hub. So, for the Samsung smartphones such as S22 Ultra, using the Bixby voice control, we can turn on/off our devices or add more automation. For this … [Read more...]
ESP32 Arduino IoT Relay Control with Google Home, Alexa and Manual Switch
Recently I have discovered a no-code IoT platform named SirnicPro for Arduino, ESP32-based projects which offers almost everything the professional IoT devices allow. No-code platform means the Arduino sketch is automatically generated. Practically there is nothing to learn since everything is click, configure and generate. This is kind of project is quite difficult to produce with a … [Read more...]
ESP32 Arduino IoT Relay Control (PHP MySQL Based Self Hosted)
This is the first guide for the series of guides to replace the setup for IBM Watson IoT based projects. If you look at our old articles and GitHub repository, you will realize that we were publishing IBM Watson IoT-centric sketches for the past 4 years. A significant time and effort were spent and our innocent readers were using them. Suddenly they came to know that IBM Watson IoT platform will … [Read more...]
ESP32 Arduino WS2811 Pixel/NeoPixel Programming
The WS2811, WS2812, WS2812B, WS2813, and SK6812x are known as NeoPixel or Pixel. They are RGB LEDs with a controller. Particularly WS2811 RGB LED strings are commonly sold in India during Diwali and in North America during Halloween, Christmas etc. Bhoot Chaturdashi in India and Halloween in North America are equivalent. Indian wedding typically involves a lot of lighting. These occasions … [Read more...]
ESP32 Arduino : Control LED with a GUI Toggle Button
Designing two buttons with separate ON/OFF functions is easy and usually, we can avoid async server or dynamic programming language. When we need a checkbox, we can use Javascript on the server side. iOS style toggle button is essentially a checkbox (or a radio button or it can be anything similar). Fundamentally toggle button is a "cheating"! You can create a toggle switch just with CSS 3. It is … [Read more...]
What are the Best Arduino Projects for Beginners?
Arduino is a platform which combines open-source software and hardware. Apart from the official Arduino, there are Arduino-compatible boards (such as ESP32) which can use the Arduino IDE to let you upload the program. The best projects for Arduino for beginners are limited to the basic projects which help the creators to understand the theory of electronics. On this website, we have over 200 … [Read more...]
ESP32 and Coin Vibrator Motor
Coin vibration motors or small vibration motors can be used for different purposes, such as an alert instead of a beep. A Vibration Motor Module is sold which includes the required resistors and transistors. They cost around $3-$4 per piece. 10mm and 12mm coin vibration motors are also sold as a component. If you are using the module, you can connect : ----------------------- ESP32 | Vibration … [Read more...]
Raspberry Pi Pico vs ESP32
You can get the Raspberry Pi Pico on Amazon for just under $4 plus shipping costs. The much older ESP32 you get in various forms for just under $10. You see, you get the ESP32 for a little more money with additional sensors or a display to display sensor data (or even the IP address of the microcontroller) or a camera. On the Raspberry Pi Pico, there are quite new chip RP2040 installed which was … [Read more...]
How to Make ESP32-CAM IP Camera Access from Anywhere in the World
First and foremost thing to warn - you can not compare the pro-grade IP cameras, something like EZVIZ IP camera with ESP32-CAM IP camera. ESP32-CAM IP camera module is dirt cheap and it is great to increase the number of video capturing devices. I would suggest you have some pro-grade camera to cover the main unsecured points of house/office and use ESP32-CAM IP camera module as an "add-on" to … [Read more...]
How to Use PWM in ESP32
Pulse Width Modulation (PWM) is a widely used technique for power delivery. ESP32 has dedicated hardware for PWM. Pulse-width modulation (PWM) of a signal or power source is a technique in which the duty cycle of a periodic signal (a sinusoidal or a square signal, for example) is modified. The duty cycle of a periodic signal is the relative width of its positive part relative to the period. … [Read more...]
