I'm trying to build a maze-solving robot using three ultrasonic sensors. Can someone guide me on the components I should use? - Should I use three ultrasonic sensors or one ultrasonic sensor with a servo motor? - What other components should I consider, like an OLED display for showing the status ...

I am building a CNC plotter using an Arduino UNO. To convert images into G-code, I use UGS, JSCut, and Inkscape. The plotter is driven by three 28BYJ-48 stepper motors (5V), though I’ve also tried using 12V motors. While the plotter moves correctly in the UGS software, the Y-axis (which controls the ...

The first robot I’m developing is an ESP32-based robotic arm, which I control through a web interface. This arm is equipped with four servos, enabling precise movement and control. It also includes a record and play button, allowing me to record movements and replay them later. Inspiration:- I was i ...

I created a soil irrigation system using an ESP8266 that I use daily. The Smart Irrigation System automatically waters plants based on soil moisture levels. It uses an ESP8266 for Wi-Fi connectivity, an OLED display to show information like humidity and temperature, and a relay to control the water ...

Recently, I purchased the Pro-Range Home Automation kit from Robu.in and started working on a home automation project. This kit offers a user-friendly solution for controlling various home devices via Bluetooth. It includes an Arduino Uno as the central controller, an HC-05 Bluetooth module for ...

I’m developing a smart irrigation system using ThinkSpeak. How do you plan to balance the real-time data collected on humidity, temperature, and soil moisture with the goal of optimizing water usage for different types of plants? Are there specific algorithms or data analysis methods you are c ...

Aap ne diye huye saree suggestions try kiye but still same issue he. kohi dusra Problem ho sakta he ky, ya kohi specific part jis vajise ye issue aa raha he..?

When uploading code to the Arduino UNO the following error occurs: "A fatal error occurred: Timeout waiting for packet content."

How can the integration of IoT sensors in a smart home system improve energy efficiency and reduce overall energy consumption
