As we discussed in my previous column, until a few weeks ago, the Arduino Uno microcontroller development board we’ve all grown to know and love was the R3 (“Revision 3”).This little rascal is powered ...

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 ...

Original Circuit Diagram: Arduino UNO R3. Now, have a look at our favorite Arduino UNO to find out the AVR chip inside. It is ATMega328P-PU, a low-power version of the traditional ATMega328-PU. The P ...

Arduino midi foot switch controller. this project contains all the information needed to modify an existing footswitch (Marshall JMD:1 footswitch) in order to make it a MIDI compatible USB footswitch ...

The Atmega328P-PU (IC1) chip in this circuit is infact an Arduino UNO chip, that is to say IC1 holds a small code prepared & processed using Arduino IDE. Switch S1 is the traditional reset switch as ...

That is because the Arduino part frees the FleaFPGA Uno from the breadboard: you can easily program, control and interface with the FPGA over a serial line or a wireless link using the Arduino IDE.

Startup code for the Arduino UNO R4 boards (RA4M1 processor) to change from the internal HOCO clock to an external XTAL for the main processor functions. The USB interface remains on the HOCO clock.

Smart Switch for Agriculture Irrigation – Circuit and Working The circuit diagram of the smart switch for agricultural irrigation is shown in Fig. 2. As shown, the switch is constructed around a ...

The guys and gals at Arduino have just released the latest and greatest version of the Arduino Uno. The previous generation was called the R3, so it’s no great surprise that the new generation flaunts ...
