[SeanHodgins] has a project in mind where he needs to sample over 500 analog sensors. To get ready, he made a breakout board for 32-channel analog multiplexer device he wants to use. He put the pro… ...

The thing about Arduino's I/O pins is that they come with special functions (and corresponding limitations) that beginners are generally unaware of. For instance, in the Uno board, pins D0 and D1 ...

Plug that into your Arduino and boom, temperature (and humidity!) readings. But the simple solution doesn’t hit every need, sometimes things need to get more esoteric.

The “ analogRead () ” reads the value from the specified analog pin. Arduino Uno contains a multichannel 10-bit ADC (analog to digital converter). This means that it will map input voltages between 0 ...

In comparison, the Arduino Uno, Leonardo, and Mega 2560 boards all have theoretical ADC speeds of 15 ksps. Caption Dual USB inputs and 12-bit analog I/Os.

Makers and developers that enjoy building projects using the Arduino platform might be interested in a new experimenters kit called the Tsunami, which has been created by Nick Johnson who is based ...

It is equipped with 32 Inputs (16 x digital 4-30V, 8 x analog 0-10V, 4 x analog 0-5V, 4 x analog 4-20mA) and 20 Outputs (8 x relay 250V/5A, 2 x open-collector 30V/1A, 8 x analog 0-10V) and offers ...

The Uno Rev3, is a great beginner board as it's included in many starter kits. It's also complemented with a host of online resources that even without the official Projects Book from Arduino, you ...

Massimo Banzi, co-founder and chairman of Arduino, announced the UNO R4 during Arduino Day 2023. He believes the UNO R4 is a new chapter in the UNO story and the perfect way to move forward, ...
