I trying to determine why the LED's on Pin 7 & 4 do not glow as bright as the pins on 5 & 2.
The nano circuit is for the two floor elevator project Going Down anyone . I've generated a PCB and during testing, the LED for the botto...
Working on a project using analog inputs for temperature feedback.
The Arduino code and calcs all looked OK, but the displayed values of temperature (on an SSD1315 OLED) were off by 5-10F.
The working temperature range used analog feedback of 5...
Overview
The Portenta H7 is part of Arduino's Pro series and stands out as one of the most powerful microcontrollers on the market. This is due to its STM32H7 dual-core processor, onboard wireless module supporting Wi-Fi and Bluetooth, and ...
Coinciding with the Republic Day of India (26th of Jan), Arduino has announced the launch of "Arduino UNO एक (Ek) R4 Minima" & "Arduino UNO एक (Ek) R4 WiFi" under “Make in India&rdqu...
I am reaching out to gather insights and advice on a project I am currently working on, which involves setting up an automated irrigation system for a small-scale greenhouse located in a remote area. Due to the greenhouse's location (3-4 hours aw...

In this article, we'll explore how to interface a soil moisture sensor with an Arduino Nano, enabling you to create a simple yet effective soil moisture monitoring system.
What is a Soil Moisture Sensor?
A soil moisture sensor is an electronic device...
I have a PHD ULTRA syringe pump from Harvard Apparatus. I want to establish communication between an Arduino and the syringe pump. The company provided me with a Python code, but Arduino does not support Python. Therefore, I converted this code to C+...
Hello, I recently started putting together a diy spot welder made from microwave oven transformer and while I was waiting for some parts to be delivered I pretty much had the spot welder working and ready to put in the case I was going to use. So the...
Having researched for a way to control NeoPixels with a Arduino Portenta I was surprised how much information there was available yet nobody had yet created a working library. I spent the past few days getting this working myself so I wanted to provi...
In July I received an Arduino UNO R4 minima development board and an Arduino UNO R4 WIFI sent by Arduino thanks to tariq.ahmad from project14. I tried them, I did a small project with the WIFI version, Arduino UNO R4 WI...

A while back, I experimented with quite nice “H450” motor driver modules (see Using H450 (Toshiba TB67...
Hello everyone, I'm trying to make a small dvd-based cnc machine that contains two small stepper motors, but in each video on youtube the height between x and y is not specified, here are the links some video to understand if someone has an idea ...
I received an Arduino Oplà IoT Kit as a mystery prize in the Save the Bees Design Challenge. This is a quick look at it and what it can do....
Oplà seems to be a village near Milan or a bar in Milan or a restaurant.

I've been going through my parts collection to see what sensors I have that might be easily used with the Uno R4 that element14 and Arduino were kind enough to send me. I was surprised at how much I had readily available.
I did a RoadTest o...
The good folks at element14 sent me a set of the new Arduino Uno R4 boards to play with, and today I finally had some time to try them out (hooray for the rainy day!).
When you first power up the R4 WiFi, it does a neat little startup animation on th...

I’ve purchased the Arduino Nano holders above in the past for projects.
I have gone one step further and created PCB’s to hold a Nano and a JQ6500 sound module. I can share the KiCAD files if someone is interested. I reluctant to post t...
MQTT is a widely used protocol in IoT space, with low overhead and targeted towards constrained devices. However they are not real time and full-duplex. and when that is needed WebSocket can be an alternative. Moreover WebSocket can take more payload...

I'm working on a Hack the Holidays project where I need to add an ambient light sensor to a Seeed Xiao BLE to control the brightness of Neopixel LEDs.
I decided to test the sensor on another Xiao (SAMD21) before trying to use it in the proj...
I just noticed this on the official arduino blog - Micropython Officially Becomes Part of the Arduino Ecosystem.
I've used OpenMV with my Potenta H7 and Nicla Vision, so it's nice to see that Arduino is going to support Micropython in th...
We all have these 5V Arduino relay breakout boards. They work on 5V, and expect a 5V control signal from your controller.
They work very well in that 5V / 5V setup. But these days, most microcontrollers have 3.3V for a logic high, not 5V. And ...
I like to revisit this question from time to time to see what is new and could bring about a change. Knowing the community's broad user base, I thought it would be a good place to ask. Maybe a poll would have been a better tool to gather response...
