| Answer to: New Pi Pico 2 by Raspberry Pi—What are your opinions? | 2 Relevance | 2 years ago | nathan | RPi Pico | |
| ... to tackle more complex tasks. Personally, I’ve always appreciated the balance of power and simplicity with the original Pico, but these upgrades might make the Pico 2 a more versatile tool for hobbyists. I’m particularly interested in how the increased memory could improve multitasking on the Board. It might even make the Pico 2 a stronger competitor against some of the more expensive microcontrollers out there. What blew me is the price they are selling it for, just $5 for this, is insane That said, I’m also curious about power consumption and heat mana ... | |||||
| Answer to: How can I safely power a BLDC motor from a hard disk drive? | 1 Relevance | 4 months ago | Divyam | Theoretical questions | |
| ... but may be difficult; a microcontroller + driver is great for learning but not the easiest. To find the pinout, measure resistance with a multimeter: with 3 wires, all pairwise readings should match (the three phases); with 4 wires, the pin that reads the same to all others is the neutral; phase order only affects direction, so swap any two leads to reverse. To avoid damage, never apply DC across two leads, don’t stall the rotor, keep leads short (with a decoupling capacitor near the driver), and WAtch temperature. | |||||
| Answer to: SPI vs I2C vs UART: which interface should I use for my application and why? | 1 Relevance | 4 months ago | Jaden | Theoretical questions | |
| I²C is the best single interface choice for on-board sensors when the priorities are minimal pins, low power, and reliable data. It uses just two shared wires, is supported by a wide range of low-power sensors, and enables software power-down strategies; address conflicts and pull-up sizing are the main practical considerations, both of which have straightforward hardware or firmware workarounds. If desired, a follow-up reply can include example pull-up values, suggested load-switch parts for power gating, or a short checklist to confirm sensor address and sleep capability before PCB finalization. | |||||
| How can I interface an AI camera module with Arduino? | 1 Relevance | 6 months ago | DIY Electronica | Hardware/Schematic | |
| I’ve seen AI camera modules (like ESP32-CAM, HuskyLens, and OpenMV) that can perform tasks such as face recognition, object tracking, and color detection. I’m curious about how these modules can be interfaced with an Arduino Board. Can Arduino Uno or Nano handle direct data processing from these AI modules, or do they just act as a controller? What’s the best WAy to connect them—UART, I2C, or SPI? Are there any limitations when using AI modules with Arduino compared to ESP32 or Raspberry Pi? | |||||
| Answer to: I’m getting noise on my analog readings—how can I clean them up? | 1 Relevance | 7 months ago | Mehjabeen | Arduino | |
| Analog noise in Arduino readings is common, especially with sensors like potentiometers or temperature sensors. To reduce it, start by adding a 0.1µF to 1µF capacitor between the analog pin and ground to filter high-frequency noise. Use a stable power source instead of USB and keep analog wires short to avoid interference. Shielding cables and using twisted pair wires can also help. On the software side, try an exponential moving average (EMA) filter for smooth readings without much delay. You can also use analogReference(INTERNAL) for better voltage stability if your Board supports it. Combining basic hardware filtering with lightweight software smoothing usually provides the best results. | |||||

| ESP32 not detected. No COM port displayed on my PC | 1 Relevance | 1 year ago | Sophie | ESP32 | |
| Hey guys, I recently purchased an ESP32-Wroom-32 dev Board(38 pins). When I connect it to the laptop using a USB, nothing happens. The COM port shows nothing and ESP32 is not detected by the system. The power LED on ESP32 flashes two to three times before going off. Also, when pressing the Reset button, the LED flashes and then turns off. Any help would be appreciated. | |||||
| Answer to: Why should one buy original Arduino boards and not clones? | 1 Relevance | 1 year ago | LogicLab | Arduino | |
| I never faced any issues with Arduino UNO or Nano clones. It's all about your choice- Do you WAnt an original Board(the tag of being called original) or are you happy with a clone one which is exactly the same! | |||||
| Arduino UNO R4 Wi-Fi Project ideas! | 1 Relevance | 1 year ago | Daniel | Arduino | |
| Hi everyone, I recently received my first Arduino UNO R4 WiFi, and I am very excited to test its capabilities. I would love to explore some project ideas using this Board. If you have any suggestions for interesting projects, whether they involve IoT applications, sensor integration, data logging, or interactive features, please share! | |||||
| What is EEPROM in Arduino and how to use it? | 1 Relevance | 1 year ago | techy ishan | Hardware/Schematic | |
| Hi everyone, I’m new to Arduino and would like to understand how EEPROM works. Can someone explain what EEPROM is and how it differs from other types of memory on the Arduino? I’d appreciate some guidance on how to store and retrieve data using EEPROM, especially to ensure the data remains after powering off the Board. I’ve also read that EEPROM can only be programmed a limited number of times. Is that true? If so, could you explain a bit more about it? Thank you | |||||
| Answer to: Do I really need anti-static precautions when handling ICs? | 1 Relevance | 7 months ago | Deboojit | Theoretical questions | |
| ... The damage might not be immediate or obvious; it often causes latent failures that show up later during operation. Certain types of chips are more sensitive than others—CMOS devices, including many logic ICs and virtually all microcontrollers, are especially vulnerable due to their delicate internal structures. In contrast, older TTL logic chips (like the 74LS series) are somewhat more robust but still not immune. If the IC is already soldered onto a Board, the risk is lower because the surrounding circuitry and ground planes can help dissipate any static ... | |||||
| Do I really need anti-static precautions when handling ICs? | 1 Relevance | 7 months ago | Techyguy | Theoretical questions | |
| I'm working on a small project with some ICs (mostly logic chips and a microcontroller), and I keep seeing WArnings about static electricity damaging components. But honestly, I’ve handled a lot of parts with bare hands and never had one fail—at least not immediately. That got me wondering: Can static electricity actually kill an IC just from touching it? Are certain types of chips (like CMOS or microcontrollers) more sensitive? If the IC is already soldered onto a Board, is it still at risk? I don’t have a proper anti-static mat or wrist strap ... | |||||
