Arduino uno

Arduino Uno is a microcontroller board based on the ATmega328P ( "Uno" means one in Italian and was chosen to mark the release of Arduino Software (IDE) 1.0. The Uno board and version 1.0 of Arduino Software (IDE) were the reference versions of Arduino, now evolved to newer releases. The Uno board is the first in a series of USB Arduino boards, and the reference model for the Arduino platform; for an extensive list of current, past or outdated boards see the Arduino index of boards.

The Arduino is a microcontroller board that you can program to read information from the world around you and to send commands to the outside world (inputs and outputs). The Arduino is a great tool to start into electronics and programming and it is used worldwide by makers, students and even engineers.

• • IC: • Clock Speed: 16MHz on Uno board, though IC is capable of 20MHz maximum at 5 Volts • • • • USART peripherals: 1 (Arduino software default configures USART as a 8N1 UART) • I2C peripherals: 1 • SPI peripherals: 1 • Operating Voltage: 5 Volts • Digital I/O Pins: 14 • PWM Pins: 6 (Pin # 3, 5, 6, 9, 10 and 11) • Analog Input Pins: 6 • DC Current per I/O Pin: 20 mA • DC Current for 3.3V Pin: 50 mA • Size: 68.6mm x 53.4mm • Weight: 25 g • ICSP Header: Yes • Power Sources: • USB connector. USB bus specification has a voltage range of 4.75 to 5.25 volts. The official Uno boards have a USB-B connector, but 3rd party boards may have a miniUSB / microUSB / USB-C connector. • 5.5mm/2.1mm barrel jack connector. Official Uno boards support 6 to 20 volts, though 7 to 12 volts is recommended. The maximum voltage for 3rd party Uno boards varies between board manufactures because various voltage regulators are used, each having a different maximum input rating. Power into this connector is routed through a series diode before connecting to VIN to protect against accidental reverse voltage situations. • VIN pin on shield header. It has a similar voltage range of the barrel jack. Since this pin doesn't have reverse voltage protection, power can be injected or pulled from this pin. When supplying power into VIN pin, an external series diode is required in case barrel jack is used. When board is powered by barrel jack, power can be pulled out of this pin.

After playing with microchip some yrs ago, now its got too expensive. Decided to find out about Arduino. Received UNO R3 earlier than expected from Italy. Downloaded IDE 2.0.4 for Mac and its really so easy. Ive tried some of tutorials and like it. Have got to learn many of the software instructions before i think of some project to try. I,m 78 and have to keep the grey matter working. Helps that i was electrical/electronic engineer but programming is new to me. Very pleased with my purchase and at reasonable price. Kevin Delivery was horrible. Parcel was delivered to a shop that closes at 5pm. Problem being, that i arrive in my home town around 4:55 to 5:15pm, depending on traffic. i tried to pick it up every day until yesterday. only day i arrived on time the store was closed tue to "health-related reasons". maybe chose a dhl postbox or a store with longer opening-times next time.
