In other cases you would need to resort to using some of the analog pins as digital pins or even moving up to an Arduino Mega which has many more I/O pins. But there is another solution. Use the I2C bus adapter for the LCD display and connect using I2C. This only consumes two I/...
Next, we define the register addresses for the two potentiometers in the MCP4231. We also define pins for Chip Select and analog inputs and variables for analog data values and wiper position values. After that, we define two nearly identical functions that can easily be combined into one. ...
Analog pins in the Arduino board are marked with the letter ‘A’ e.g. a0, A1, A2, A3, A4. That means it has 5 built-in analogs to digital converter channels. Only these analog pins of Arduino can be used to measure analog signals. But If you want to use more channels, you can...

functional PCB. In this tutorial you will learn, basic FM working, Arduino code for this FM, range, speakers, antenna and amplifiers used in this circuit. This type of digital circuits has a very big importance over any analog based circuits. It will reduce the circuitry and tuning methods....
I drew a circuit in EasyEDA which included all the components on the breadboard – the ICs, Arduino Nano and HC12 module which are connected to the digital pin of the Arduino. I have also added some headers which are connected to Analog Pins and Digital Pins of These buttons will be use...
It focuses on designing an interface for communication, which acts as the motion control platform, between the robotic arms and Arduino micro controller. Arduino in this system receives the angle value and fed into the computer to be processed. By using an analog servo, which is cheap, the ...
Intensity of the light is controlled by using PWM (pulse width modulation). The Arduino and other digital devices cannot give analog output; they can only give the digital output (High or Low). Means they can only turn OFF and turn ON the device, but sometimes we need the voltage between...
This library enables you to use Interrupt from Hardware Timers on supported Arduino boards such as AVR, Mega-AVR, ESP8266, ESP32, SAMD, SAM DUE, nRF52, STM32F/L/H/G/WB/MP1, Teensy, Nano-33-BLE, etc.As Hardware Timers are rare, and very precious assets of any board, this ...
It reads the analog value from the Arduino boardif (state==0) set the led1 as HIGH if (state==1) led1,led2 are HIGH if (state==2) led3 is HIGH if(state==2)led2 is HIGH And set the delay time as 1000 s for the 3 led's and create the function called Traffic with ...
