June 13th, 2019 Nilesh Chaurasia 
Arduino LED Blink Code or Project LED blinking or toggle program is one of the basic practice to test everything working properly. In the blinking program digital pins are on and off continuously with a delay. Arduino Uno is one of very popular board these days, and it is having a build-in LED on pin […] Arduino Button or Switch Interface Circuit without Pull Up Resistor
June 14th, 2019 Nilesh Chaurasia 
Arduino Button or Switch Interface Circuit To take digital input we have to interface button or switch with the Arduino board. Interfacing switch is requires a resistor and it is known as pull up resistor. Figure 1 below shows the circuit diagram of button interfacing. It is having a 10k resistance which is connected with […] Arduino LED Fade Code with analogWrite function on Analog Output or PWM Pins of Uno Board
June 15th, 2019 Nilesh Chaurasia 
Arduino LED Fade with PWM Arduino LED Fade Code is used to test the PWM feature of board. Fading mainly uses analogWrite function on Analog Output Pins of Arduino Board. Arduino does not have DAC (Digital to Analog Converter) capability, but in place of DAC it is having PWM (Pulse Width Modulation) capability. The PWM […] Arduino Serial Communication Port Test Example with write and begin Function
June 15th, 2019 Nilesh Chaurasia 
Arduino Serial Port Communication Arduino Serial Communication is used to communicate over serial port with terminal devices over UART like PC. Understanding the serial communication in the Arduino is very important because these days many devices uses UART interface, like GPS, ESP8266, GSM and RFID modules. The UART serial communication is a full duplex, means […] Arduino Serial read, available Function Example and UART Loopback

Arduino Serial read Arduino serial library have in-built function to receive the data over serial port. To test the receive function in Arduino you have to send data from PC/Laptop with serial monitor program. In this article we will tell you more about serial communication in the Arduino to implement receive function. Arduino library have […] Arduino Analog Input read from Pin with the help of analogRead function from Potentiometer
June 15th, 2019 Nilesh Chaurasia 
Arduino Analog Input or Read with analogRead Function Arduino board have build-in Analog To Digital Converter to take analog inputs. Arduino have a function called analogRead. Analog input features is required to interface analog sensors like, LM35 temperature sensor, LDR light sensor etc. Arduino UNO have 10 bit analog to digital converter. It means the […] Arduino Serial Print and Println Function to Send Integer Variable And Text Program Code
July 11th, 2019 Nilesh Chaurasia 
Arduino Serial print Function Application Serial.write() function send the data in ASCII code. It means if you want to send the value of a integer variable with the help of write function you have to convert value into ASCII format. For example if suppose a variable x having value 87 x = 87; and we […] Arduino Serial finduntil Function and its Application with Example
July 27th, 2019 Nilesh Chaurasia
What is Arduino Serial findUntil Function Arduino Serial findUntil Function reads the received buffer and test for specified string or word present or not. If specified string is present in the buffer than the function return the true, otherwise return false. By default the findUntil function wait for terminating character before it return false. The […]
Arduino Serial Read String Until with ReadStringUntil Function Example
August 5th, 2019 Nilesh Chaurasia 
Arduino Serial Read String Until Function – Serial.readStringUntil Arduino Serial readStringUntil Function reads the serial port into the string variable, until it receive the terminating character. By default the readStringUntil function wait for terminating character or timeout to complete. The Serial.readStringUntil() function wait for timeout, which is one second by default. If the terminating character […]
