| Shift Register Cascading Issues | 1 Relevance | 12 months ago | Electronix | Theoretical questions | |
| I'm trying to cascade multiple 74HC595 shift registers to expand the number of digital outputs in my Project. While one shift register works perfectly on its own, as soon as I add the second (and especially the third), I start getting strange or inconsistent output—some LEDs don’t light up correctly, or they shift out of order. Is there a timing issue I might be overlooking? Do I need to delay between latching and shifting? Could signal integrity or voltage drop be the issue when chaining several ICs? | |||||
| Answer to: Can anyone suggest a new ESP32 board? | 1 Relevance | 12 months ago | Paul | ESP32 | |
| Several new ESP32 boards have gained popularity in the community recently, each for different reasons depending on the use case—AI, low power, display integration, or future IoT protocols. Here's a breakdown of the most liked ones: ESP32-S3 1. Native USB support (no external serial chip needed)2. Supports AI instructions for image/speech processing ESP32-C3 1. Based on RISC-V architecture 2. Ultra-low power for battery-operated devices M5Stack Series 1. Includes display, case, and built-in sensors2. Modular design for quick and easy prototyping ESP32-C6 1. Features Wi-Fi 6 + Bluetooth 5 + Thread/Zigbee Each has its strengths, so the "most liked" depends on the user's Project needs. But overall, ESP32-S3 and ESP32-C3 are currently leading the popularity charts. | |||||
| Answer to: STM32 vs Arduino: Which One is Better? | 1 Relevance | 2 years ago | electronicb_brain | Hardware/Schematic | |
| I think it really depends on the type of Projects you're working on. If you're mainly doing simple LED displays, motor control, or basic IoT Projects, Arduino boards are perfect. They’re simple and get the job done without much hassle. But if you WAnt to dive into audio processing, real-time data acquisition, or anything that requires heavy computation, STM32 is a beast. I switched over when I started working on a DIY oscilloscope Project because I needed faster ADC and more memory. | |||||

| Answer to: What is the difference between L293D and L298N Motor Driver? | 1 Relevance | 2 years ago | TechSpark | Theoretical questions | |
| Hey Tristan, The L293D and L298N are both H-bridge motor drivers commonly used to control DC motors, but they have some key differences. I’ve summarized these in the table below, allowing you to easily compare and choose the one that best suits your Project requirements. Attachment : Difference-between-L293D-and-L298N.png | |||||

| What is the difference between L293D and L298N Motor Driver? | 1 Relevance | 2 years ago | Tristan | Theoretical questions | |
| Hey everyone, I’m a bit confused about the differences between the L293D and L298N motor drivers. They both seem to be used for controlling DC motors, but I’m not sure which one I should be using for my Project. From what I understand, they have different current and voltage ratings, but I don’t quite get how that affects the choice between them. Could someone help clarify when to use the L293D vs. the L298N? Are there any situations where one is clearly better than the other? Thanks | |||||

| ... also the P4-Function-EV-Board if you WAnt to experiment with multimedia interfaces or build smart displays (it supports a 7-inch touchscreen). For IoT stuff, ESP32-C6 is really catching on. It supports Wi-Fi 6, BLE 5.3, Thread, and is Matter-ready. Boards like the XIAO ESP32C6 (from Seeed) or the ESP32-C6 DevKitC-1 from Espressif are solid picks if you're working on low-power or Matter-based devices. Also worth mentioning: 1.Arduino Nano ESP32: Compact, beginner-friendly, and based on the ESP32-S3. 2.ESP32-S3-BOX-3: Powerful AIoT dev kit in a ni ... | |||||

Based on readings, display your plant’s "mood" using emojis on an OLED or in a mobile app. Could also send WAtering reminders if the soil is dry. 3. Wi-Fi Jammer Detector With just an ESP8266, you can scan Wi-Fi channels and detect when there's suspicious interference or sudden drops in signal — send an alert if something looks off. Simple but cool networking concept. 4. IoT Trash Bin Level Monitor Use an ultrasonic sensor to measure h ... | |||||
| How can I run multiple tasks at once without using delay() in Arduino? | 1 Relevance | 1 year ago | J.Smith | Arduino | |
| I'm working on an Arduino Project where I need to run multiple tasks simultaneously—for example, blinking an LED, reading a sensor, and checking for button input. Initially, I used delay() for timing, but I realized it blocks the program and prevents other tasks from running smoothly. What is the recommended WAy to handle timing and run multiple tasks without using delay()?Should I use millis() or is there a better approach like using timers or a task scheduler? I'd appreciate examples or tips on how to structure the code for multitasking in Arduino. | |||||

| How to identify LED terminals? | 1 Relevance | 2 years ago | Aiden | Theoretical questions | |
| Hi everyone, I'm working on a school Project that involves LEDs. I came across an LED where both the anode and cathode leads are of equal length, making it difficult to distinguish between them using the typical lead length method. Additionally, the internal structure of the LED is not visible. What are some reliable methods or techniques I can use to accurately identify the anode and cathode terminals in this situation? | |||||

| Why Use a DC Motor Controller Instead of a Potentiometer? | 1 Relevance | 2 years ago | hobart bess | Circuits and Projects | |
| Hi everyone, I'm currently working on a Project that involves controlling the speed of a DC motor. I understand that a potentiometer can be used to control the speed of a motor by varying the resistance, which in turn adjusts the voltage supplied to the motor. Given this, I'm curious about the need for dedicated DC motor controllers. Why should I consider using a separate motor controller when a simple potentiometer seems to achieve the same result? I'd appreciate it if someone could explain the advantages or scenarios where a DC motor controller is preferred over a potentiometer for speed control. thank you | |||||
| Can i use EN pins for PWM speed control in L298N Motor driver? | 1 Relevance | 2 years ago | TechSpark | Hardware/Schematic | |
| hey everyone, To properly control the speed of my DC motor in my current Project, I need to know if the ENA and ENB pins on the L298N motor driver can accept PWM signals to vary the motor speed, or if these pins are only used for switching the channels ON and OFF. Any guidance on using these pins for speed control would be greatly appreciated. | |||||
