Help with a build
So I just recently got an Arduino and have been playing around with the builds included in the kit, one of them has a water pump but no matter what I try to do it just won’t work, I attached a pic of my build and the build on the website.
How to connect 5v digital signal to ESP32 GPIO (3.3v) pin
Complete beginner here. I have an ESP32 dev board, powered by a MicroUSB cable, connected to a breadboard. I also have a YF-S201 Hall Effect Flow sensor, powered by 5v and outputs digital pulses that correspond to flow, also at 5v. I understand that the ESP32 needs 3.3v inputs. How do I go about doing this?
I am currently powering the sensor using the VIN/GND pins off the ESP32 board. Google badly wants me to use a logic-level shifter, which I purchased. However, when I wired it up as Google suggests, it clearly messes something up with the board. I am feeling overwhelmed and frustrated and just need someone to point me in the right direction! Thank you!
It is possible I fried either the logic level shifter or the YF-S201. When I started, I could get variable voltage off the signal wire by blowing through the valve. Not so much anymore... Or was I seeing ghost voltage? Can I read digital pulses with a multimeter? I have so many questions 😭...
Where should i put the capacitor ?
I wanna make a nrf24 wireless communication but idk where to put the capacitor. I have nrf24 adapter.
Cant Upload anything to my Pro trinket 5V/16Mhz
Hi All, can someone help me get my pro trinket to work? In my eyes i do everything correct but it looks like arduino is not uploading anything to it.
1. Trinket is listet in system manager,
2. Driver is installed on it.
3. Pro trinket 5V/16Mhz is selected in arduino
4.USBtinyISP is used as programmer....
Help with Arduino Nano 33 Sense Rev2 connection
Hello Everyone,
I am new to the world of TinyML and micro-controllers. I have bought a Arduino Nano BLE Sense 33 Rev2 board. Installed the Arduino IDE 2.3.6 (latest) software. Then I installed the Arduino Mbed OS Nano Boards drivers through the IDE. Restarted the IDE and connected my board using the USB-C cable to my Windows 11 laptop.
When I go to Tools -> Port in the IDE, I see only COM4 and COM3 but no boards shown. The "yellow" LED on board is blinking so it seems the board is ready but Windows is not able to detect it. ...
Finding Suitable Encoder for my DC Motor
Hi everyone,
I'm working on a project where I'll have a DC motor spinning a flywheel at high RPM. To accurately control its speed, I want to attach an encoder to the motor. Here's information on the motor I'll be using: https://www.nbleisonmotor.com/RS-365-Dc-Micro-Motor-pd6003204.html.
Initially I planned on using the AS5600 absolute magnetic encoder. Because the shaft of the motor is exposed on its back, I thought of designing a 3D-printed part that would mount the AS5600 so that the sensor is placed right below the spinning shaft. However, the encoder did not seem to pick up any readings, probably because the shaft of the motor is too weak of a magnet, or too small....
3.5" TFT Screen ILI9488 shows only white
Hello!
I am a rather beginner Arduino tinkerer and I recently bought a 3'5" TFT Screen ILI9488 4-wire SPI to play with bigger screens, I previously experimented successfully with SSD1306 screens.
Upon wiring the TFT screen to a ATMEGA2560 (Elegoo Mega) board, the screen fills with white.
When I upload a basic .ino example using the TFT built-in library from the Arduino IDE, the screen remains white and nothing seems to change....
Inconsistent LED brightness
I have three LEDs which are each operated by an individual button and two sets of code, one that keeps LEDs on after being pressed and another that keeps LEDs on only if the button is held. Set up is the same in both pictures but the 2nd and 3rd LEDs are much dimmer in the "left on" version. I've been searching all over and haven't found anything on this issue. Anyone have any ideas on how to resolve this?
CNC Drawing Machine
Hey I followed DIY Machine’s CNC DRAWING MACHINE tutorial …
However, I think it’s setup right but it doesn’t fully move like it should. I dunno if it’s the way I personally set it up or the hardware/plugins. I did the dupoint connectors myself and they are a bit wiggly but it still moves the X axis but I got no idea why it doen’t move the Z axis or Y axis.
