In this project you’ll learn how to read from a digital I/O pin, using the digitalRead() function.Digital I/O pins on the Arduino Uno board are the ones on the USB port side of the board, and they might also be marked as digital on the pins, like in my case:...
I have an Arduino Uno connected to a servo motor and DC motors. If I create objects for the servo and for the DC motors, and then call "writeDigitalPin" to pin d10 where the DC motor is connected, the states of all of the pins are set to 0 ...

Most of the Arduino boards have low-power CMOS 8-bit microcontrollers based on AVR enhanced RISC architecture. The GPIO pins of these controllers operate at CMOS logic levels. A CMOS gate operating at 5V accepts voltage ranging from 0 to 1.5V as logical LOW and 3.5 to 5V as logical HIGH....
This application enables to control the digital I/O ports of the Arduino UNO microcontroller board through the USB interface of your Android device. All you need is an USB OTG cable and a proper USB cable for the connection. Through the user interface, you can make the digital pins INPUT ...
下列实验操作能达到相应实验目的的是选项实验操作实验目的A向FeCl3、CuCl2的混合溶液中加入足量铁粉，然后过滤提纯FeCl3B向含有Br2的苯中加入适量的NaOH溶液，然后充分振荡、静置、分液除去杂质Br2C将含有少量的NaCl杂质的KNO3固体溶于水，然后蒸发结晶提纯KNO3D向MgCl2、AlCl3混合溶液中加入过量的NaOH溶液，过滤后将沉淀溶...
Arduino Education Shield Circuit Here is an example of how to insert an SD card into the MKR Zero board. None of the examples below requires any additional circuit. Insert the SD card. Examples Below are a series of examples Read and Write ...
ADX UnO is an Arduino Uno based HF Digital Modes Transceiver. ADX is abbreviation for Arduino Digital Xceiver. ADX UnO is based on ADX – Arduino based Digital Modes Transceiver design. Here is the link for ADX – Arduino based digital modes transceiver for further information:https://antrak....
We expect to be able to use the attachInterrupt(digitalPinToInterrupt(pin), ISR, mode) syntax, even when the use of digitalPinToInterrupt is not absolutely necessary due to the interrupts having the same numbering as the pins (e.g. SAMD)...
This is a multi-functional expansion board FOR UNO R3, which is equivalent to a special MUC development board. You can write code on it to achieve the functions you need. RS485 Master-Slave Device(PLC MCU), Modbus Protocol Relay 0/4-20MA Current Collection, ...
