| Answer to: Suggest some good Arduino books? | 6 Relevance | 1 year ago | Amelia | Arduino | |
| Great to hear you’re diving into robotics! Here are a few books that I’ve personally found helpful: Arduino Robotics by John-David WArren This book is packed with robotics projects and explains how to integrate motors, sensors, and actuators into robotic systems. It’s beginner-friendly but dives deep into practical applications. Programming Arduino: Getting Started with Sketches by Simon Monk While this book isn’t robotics-specific, it’s an excellent introduction to Arduino programming. You can combine this with a robotics-focused guide for a complete ... | |||||
| What connector do I need? | 4 Relevance | 1 year ago | GPag | Circuits and Projects | |
| How can I tell what the specs are on this connector so I can replace it? I need both the male and female sides. Do any of the numbers around the connector tell what it is?It connects the PCB to a AAA battery compartment. Forgot that the batteries were left in and they caused corrosion. Also, what is the best WAy to clean up the PWB? Thanks Attachment : IMG_2024-12-17-175606.jpeg Attachment : IMG_2024-12-17-175047.jpeg Attachment : IMG_2024-12-17-175758.jpeg | |||||

| Answer to: ESP32 not detected. No COM port displayed on my PC | 4 Relevance | 1 year ago | Admin | ESP32 | |
| Hey, this is a very common issue. Let’s troubleshoot: Check the USB Cable: First, make sure you’re using a data-capable USB cable. Some cables (like cheap ones for phone charging) only provide power and can’t transfer data. Try a different cable if you’re unsure. Drivers: Have you installed the necessary drivers? The ESP32 often requires the CP2102 or CH340 USB-to-serial drivers, depending on your board. You can download these from the manufacturer’s website or search for “ESP32 USB driver.” After downloading the drivers, manually install it(there will be a text file for instructions to follow.) COM Port Visibility: Open your Device Manager (Windows) or System Information (Mac) and check if the ESP32 shows up under Ports or USB Devices. If it's not there, take out the USB cable and insert it again while keeping the device manage window open. If you notice some changes, it's a good sign. So if it’s listed with an error, the drivers might not be properly installed. Power Issues: The fact that the LED turns off could indicate the board isn’t receiving stable power. Maybe either the port or connector is loose. Let me know how it goes after these steps! | |||||

| Answer to: Good circuit simulation softwares- Any suggestions? | 4 Relevance | 2 years ago | Admin | Softwares | |
| Here are some of the best circuit simulation software(online and free): Tinkercad Falstad Simulator.io Circuit.io Circuit-Cloud PartSim Docircuits EasyEDA CircuitLab CircuitSim Everycircuit You can try these on your browser without downloading anything. I personally like TinkerCad for Arduino and Falstad for analog/digital circuit simulation. If you are looking for circuit simulation software to download(paid and free), here is the list: NI MultiSim Autodesk Eagle LTspice PSIM EasyEDA KiCAD CEDAR Logic Simulator Tina TI idealCircuit Proteus Proteus by Labcenter is the best of the best. You can do anything using it. I once simulated an 8-bit computer using register ICs etc. | |||||
| Answer to: What is the difference between L293D and L298N Motor Driver? | 4 Relevance | 2 years ago | Admin | Theoretical questions | |
| Attachment : L293D-Vs-L298N.jpeg The only important difference between the L293D and L298N motor driver module is the current rating: L293D: Can handle up to 600mA per channel (with a peak of 1.2A for brief periods). L298N: Can handle up to 2A per channel (with a peak of 3A for short bursts). So if your motors require more than 600mA of current, the L298N would be a better choice due to its higher current capacity and attached heatsink. If you ignore the rating, there is an advantage to L293D: Since the L293D IC comes in a DIP package, you can use it as it is in your circuit such as on a breadboard or a PCB. L298N doesn't offer this feature since it comes in a Multiwatt-15 package. So you are forced to buy the complete L298N module. Also, the price of the L293D IC is very low compared to the L298N module. You can read the differences between these two in detail here: L298N VS L293D | |||||
