The memory structure is shown in the below image: The Arduino UNO is a standard board recommended to beginners, while Arduino Mega is used for complex projects due to its greater memory space. What is the main difference between Arduino UNO and Arduino Mega? The Arduino Nano has a compact size and mini USB cable than the Arduino UNO. What is the main difference between Arduino UNO and Arduino Nano? Such dual functioning makes it unique to recommend and easy to use for beginners.

The cable acts as a serial port and as the power supply to interface the board. The USB port in the Arduino board is used to connect the board to the computer using the USB cable. Why is Arduino recommended over other boards for beginners? It can also act as GPIO (General Purpose Input Output) pins. The function of Analog pins is to read the analog sensor used in the connection.

TX and RX LED's- The successful flow of data is represented by the lighting of these LED's.The pins numbered from D0 to D13 are digital pins. Digital I/O pins- The digital pins have the value HIGH or LOW.When the power is OFF, the LED will not light up. Power LED Indicator- The ON status of LED shows the power is activated.ICSP pin - The In-Circuit Serial Programming pin allows the user to program using the firmware of the Arduino board.It combines Memory (SRAM, EEPROM, and Flash), Analog to Digital Converter, SPI serial ports, I/O lines, registers, timer, external and internal interrupts, and oscillator.

It can run on both online and offline platforms. It is programmed based on IDE, which stands for Integrated Development Environment. The Arduino UNO includes 6 analog pin inputs, 14 digital pins, a USB connector, a power jack, and an ICSP (In-Circuit Serial Programming) header. The board consists of digital and analog Input/Output pins (I/O), shields, and other circuits. It is easy to use compared to other boards, such as the Arduino Mega board, etc. developed the Arduino UNO board.Īrduino UNO is based on an ATmega328P microcontroller. It is considered as the powerful board used in various projects. It was also the first USB board released by Arduino. It was named as UNO to label the first release of Arduino Software. At 150☏ the relay shuts off and the current stops.The Arduino UNO is a standard board of Arduino. In this example, the relay will stay activated and let current flow through the light bulb until the temperature of the thermistor reaches 150☏.

The CodeĪfter everything is connected, upload this code to the Arduino: #include See our article on Making an Arduino Temperature Sensor for more information. If you do use a 100K Ω thermistor, you’ll need to change line 7 in the code below to Temp = log(100000.0*((1024.0/RawADC-1))). If you use a 100K Ω thermistor, use a 100K Ω resistor. For example, I’m using a 10K Ω thermistor, so the resistor should be 10K Ω as well. The value of the resistor should be the same order of magnitude as the thermistor. The thermistor part of the circuit is set up as a voltage divider. It’s dangerous to put the relay on the neutral wire, since if the device fails current can still fault to ground when the relay is off. This way the relay is on the hot side, and current is switched before it reaches the light bulb. Connect the side leading to the light bulb to the NO terminal of the relay, and the side leading to the plug to the C terminal. Identify the hot power wire (red wire in the diagram above) in the cord leading to the light bulb and make a cut.
