Today I made my first autonomous robot car which is a modification of the my first Arduino RC Car . Until now, I used bluetooth for control navigation of the diy Arduino robomaster. Now, I wanted to add autonomous driving feature to the robot car because I thought it would be great exper…
When deploying a wireless access point (AP) like the TP-Link EAP225 Outdoor , network administrators often face the challenge of serving numerous clients with unique SSIDs. While the datasheet may specify a limitation of 16 SSIDs, what happens when …
In today’s hyper-connected world, having reliable outdoor Wi-Fi access is crucial, whether for enhancing your backyard experience, ensuring robust connectivity for your business, or extending your home network into outdoor spaces. Outdoor Wi-Fi acce…
So I wanted to build a LED matrix wall using the WS2811 2811 IC RGB LED Pixels Module String Light. Each lots had 50 pieces and I bought 4 lots and so I got 200 pieces WS2811 2811 IC RGB LED Pixels Module String that operates on 5V. I have plan to …
Stepper motor control with a potentiometer can be useful. Typically the stepper motor movement are controlled with programs and usually are programmed to do repeated predefined movement for automation. On the other hand, stepper motor control with …
If your stepper motor is jerking, not moving in the preset direction or during the change of direction of motion, then it might be that your stepper motor is not wired correctly. For example, consider a bipolar stepper motor such as Nema 17 stepper …
While working with microcontroller boards like ESP32-CAM, Arduino Nano or ESP8266 NodeMCU, and other ESP32 boards I came across several problems while uploading the program code. These devices are either connected through USB(using USB To RS232/ TT…
Soldering iron tips are essential tools for any electronics enthusiast or professional. Proper care and maintenance of these tips can significantly extend their lifespan, ensuring consistent performance and saving you money. In this blog post, we…
In this tutorial, we will explore how to control a DC motor using the ESP32-CAM module. The DC motor is connected via a 5V relay, and the relay is controlled using a 2N2222 transistor and a 1kΩ resistor connected to GPIO16 of the ESP32-CAM. This pr…
When working with Arduino projects, particularly those involving 3D printers or other complex machinery, using a display can significantly enhance the user interface and overall functionality. Traditionally, many setups use a parallel LCD module con…
