The microcontroller-based concept was chosen because I wanted to scale the sensor system later to suit other applications. Here is the diagram of my Arduino infrared close proximity sensor. As you can ...

Sure, modern paper shredders already have sensors that tell you when the bin is full, but if your machine lacks this feature, you can just build it a custom sensor with an Arduino Uno.

It’s a simple matter of hooking up the Grid-EYE sensor to the Arduino Uno over I2C, and then spitting out the sensor’s data in a nice visual form on a cheap TFT screen.

The week point for accuracy is that the UNO has the analog ref tied to Vcc but you can switch analog ref to the internal 1.1Volt reference to measure and then switch everything back. See the ...

Both the Arduino Nano and Uno can be powered via their integrated USB connectors. This automatically supplies regulated 5V power to the board, allowing you to use any USB-supported power source ...

Arduino Uno - The World's Most ... The bright 12x8 red LED matrix is ideal for creative projects using animations or for plotting sensor data without the need for additional display hardware.

That’s right, these parking sensors are powered by an Arduino board, and the only extra components that were used in the project are a HC SR04 ultrasonic sensor, an active buzzer, and jumper wires.

Arduino (and Nextion) powered air hockey! Though it actually comes with a football spin... Thanks to the Arduino team for highlighting this one, a football-themed version of air hockey, which sees an ...

The official Arduino team has this week revealed more details about the new Arduino UNO R4 development Board which will be officially launching in a few months time during May 2023. The ...

The Arduino UNO R4 boasts a 3x performance increase over the UNO R3 and , in addition, SRAM has been upgraded from 2kB to 32kB, and flash memory from 32kB to 256kB to support more complex projects.
