LM35 & Memory Card This is a little DIY project with an Arduino Uno, SD card breakout board, and LM35 temperature sensor. To build a temperature logger using a microSD card, just connect the LM35 ...

The Arduino Nano and Uno are equipped with very similar processors (the chip that essentially serves as the brain of the board). The Nano features an ATmega328, while the Uno sports an ATmega328P.

Chipmaker Arduino s.r.l. today introduced a new microcontroller board, the Uno R4, that offers significantly higher performance than its previous-generation hardware. Switzerland-based Arduino is ...

[Rafael] just made a little library that allows you to interface these modules to the Atmega328p-based Arduino UNO in order to gain some memory space.

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.

But for those who fancy experimenting with the format it’s still possible to make a basic card reader using LEDs and light sensors, as [Nino Ivanov] has done using an Arduino Uno as the brains.

Melexis Technologies has introduced a Hall-effect switch/latch device with an integrated voltage regulator and on-chip non-volatile memory.

How do you create a display that effectively shows of audio clips and physical objects? Simple: you stick an Arduino in a card catalogue.

Microcomputers such as Raspberry Pi, Pine A64 and Arduino have emerged to help DIY enthusiasts build computers and computer-based devices. Here is an up-close look at these three products.
