To build an Arduino or ESP32-powered 4-wheel robot car, you need some specific parts including a special chassis. In the case of ordinary 4-wheel drive, the wheel mechanism is less complex. You need rear-wheel drive plus a front steering mechanism to properly steer. As this kind of chassis is built using the professional remote-control racing principle. They use two rods through the steering servo … [Read more...]
ESP32 Control Servo Motor Over WiFi (Basic of Robot Car)
Many hobbyists try to directly use some projects on how to build a robot car available on the internet and eventually face issues. There are various reasons why the project fails because there are differences in setup and components. A common approach to steer a robotic car to the right or left is by using a shield which uses four DC motors. The method is good for toys but not enough mature or … [Read more...]
ESP32 Arduino Water Tank Level Monitoring Using Laser ToF Sensor
Guides for building a DIY water level monitoring system using Ultrasonic Sensor and ESP32 or Arduino UNO are quite common. In real life, using an Ultrasonic Sensor for a water tank is often not practical because a water tank can have 1-2 sources of water falling to fill up the tank from the top. Also, with Ultrasonic Sensor, you need to make sure that the position of the sensor is optimum in a way … [Read more...]
Why ESP32 is a Popular Microcontroller Solution?
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...]
