  • Arduino Uno Revision 3 Development Board

    Arduino Uno Revision 3 Development Board

    UNO R3 Arduino-compatible board with the ATMega328P, ATMega16U2 and CH340G serial converter

    Since Arduino is an "Open Source" hardware as well as software anyone can duplicate the Arduino Uno R3 boards exactly, even using original parts, this means we are able to supply this Arduino compatible board at a fraction of the cost of the original but still working identicaly to the original.

    The UNO is the best board to get started with electronics and coding. If this is your first experience tinkering with the platform, the UNO is the most robust board you can start playing with. The UNO is the most used and documented board of the whole Arduino family.

    Arduino Uno is a microcontroller board based on the ATmega328P (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, an ICSP header and a reset button. The development board has everything needed to support the microcontroler to help you create an endless amount of projects and if you are just starting then the worldwide Arduino community is full of ideas, guides and help to get you started or help you complete your project.

Ultrasonic ranging module for Arduino and other microcontroller projects

 
This module has a 40kHz ultrasonic transmitter and receiver pair mounted on the front of a small PCB along with the required control circuitry on the back. The module works by sending a short 40kHz square wave out and timing how long it takes to return to the module, you can then work out the distance it has traveled by knowing the speed of sound.
 
Voltage : 5VDC
Working Range : 20mm to 4500mm
Accuracy : 2mm
