In the upper left corner of the Arduino IDE, there are two buttons, Verify and Upload. First, press the Verify button(✓) to compile.
Grove Beginner Kit For Arduino® Note: All modules are pre-wired on a single circuit board, so no cables and soldering are needed. However, if you break out the modules and want to connect them with Grove cables, please kindly check the Breakout Guide.
Grove Beginner Kit For Arduino® Lesson Guide Lesson 1: Blinking with the LED We have completed the output “Hello world” program. Now let’s learn how to light the LED module. We know the three basic components of a control system: Input, Control, and Output. But lighting up LED uses only the output, not the input. Seeeduino is the control unit, the LED module is the output unit and the output signal is a digital signal.
Grove Beginner Kit For Arduino® Hardware connection Module connection Default connection by PCB stamp hole. Connect the Seeeduino to the computer through the USB cable. Software Code Open Arduino IDE. Copy the following code, click Verify to check for syntax errors. Verify that there are no errors, and you can upload the code.
Grove Beginner Kit For Arduino® Code Analysis setup(){ } The setup() function is called when a sketch starts. Use it to initialize variables, pin modes, start using libraries, etc. The setup() function will only run once, after each powerup or reset of the Arduino board. loop(){ } After creating a setup() function, which initializes and sets the initial values, the loop() function does precisely what its name suggests, and loops consecutively, allowing your program to change and respond.
Grove Beginner Kit For Arduino® pin: the Arduino pin number to set the mode of. mode: INPUT , OUTPUT , or INPUT_PULLUP . Setting ledPin to the output mode. digitalWrite(ledPin, HIGH); Description: Write a HIGH or a LOW value to a digital pin. If the pin has been configured as an OUTPUT with pinMode(), its voltage will be set to the corresponding value: 5V (or 3.3V on 3.3V boards) for HIGH , 0V (ground) for LOW .
Grove Beginner Kit For Arduino® Parameters: ms: the number of milliseconds to pause. Allowed data types: unsigned long. Delay the program by 1000ms(1s). Demo Effect and Serial Print Result: The LED module will be 1 second on and 1 second off. Breakout Guide If modules are broken out from the board. Use a Grove cable to connect the Grove LED to Seeeduino Lotus’s digital interface D4.
Grove Beginner Kit For Arduino® Lesson 2: Pressing Button to Light Up LED The first thing we need to know is that the input of the button is a digital signal, and there are only two states, 0 or 1, so we can control the output based on those two states. Practice: Use button to turn ON and OFF the LED module Components Involved 1. Seeeduino Lotus 2. Grove LED 3. Grove Button 4. Grove Cables(If broken out) Hardware connection Module connection: Default connection by PCB stamp hole.
Grove Beginner Kit For Arduino® Output: LED module Both the sensor and the LED use digital signals, so they should be connected to digital interfaces. Software code: Open Arduino IDE. Copy the following code, click Verify to check for syntax errors. Verify that there are no errors, and you can upload the code. //Button to turn ON/OFF LED //Constants won't change.
Grove Beginner Kit For Arduino® Code Analysis pinMode(ledPin, OUTPUT); Define LED as the output unit. pinMode(buttonPin, INPUT); Define button as the input unit.
Grove Beginner Kit For Arduino® buttonState = digitalRead(buttonPin); Description: Reads the value from a specified digital pin, either HIGH or LOW . Syntax: digitalRead(pin) Parameters: pin: the Arduino pin number you want to read This function is used to read the states of digital pins, either HIGH or LOW. When the button is pressed, the state is HIGH, otherwise is LOW.
Grove Beginner Kit For Arduino® Syntax: if (condition1) { // do Thing A } else if (condition2) { // do Thing B } else { // do Thing C } The usage of the statement is: if the logical expression in parentheses is true, execute the statement in curly braces after if, if not, execute the statement in curly braces after the else. If the state of the button is high, the LED pin outputs a high level and turn the LED on, else turn LED off.
Grove Beginner Kit For Arduino® Lesson 3: Controlling the Speed of the Blink In the last section, we studied that button only has two states, ON/OFF state corresponding 0V and 5V, but in practice, we often counter the need for many states, not just 0V and 5V. Then you need to use Analog Signal! Rotary Potentiometer is a classic example that uses an analog signal.
Grove Beginner Kit For Arduino® Hardware connection Module connection: Default connection by PCB stamp hole. The Seeeduino is then connected to the computer via a USB cable. Hardware analysis: Input: Rotary Potentiometer Control: Seeeduino Lotus Output: LED module The input is an analog signal, so it is connected to the analog signal interface, the LED module is connected to the digital signal interface.

After a call to analogWrite(), the pin will generate a steady rectangular wave of the specified duty cycle until the next call to analogWrite() (or a call to digitalRead() or digitalWrite()) on the same pin. Syntax: analogWrite(pin, value) Parameters: pin: the Arduino pin to write to.
Grove Beginner Kit For Arduino® Lesson 5: Making an Light Induct LED The light sensor contains a photosensitive resistor to measure the intensity of light. The resistance of the photosensitive resistor decreases with the increase of light intensity. The output signal is the analog value, the brighter the light source, the larger the analog value. Based on this property, you can use it to make a light switch.

Grove Beginner Kit For Arduino® Code Analysis Serial.begin(9600); Description: Sets the data rate in bits per second (baud) for serial data transmission. For communicating with Serial Monitor, make sure to use one of the baud rates listed in the menu at the bottom right corner of its screen. You can, however, specify other rates - for example, to communicate over pins 0 and 1 with a component that requires a particular baud rate. An optional second argument configures the data, parity, and stop bits.
Grove Beginner Kit For Arduino® outputValue = map(sensorValue, 0, 1023, 0, 255); Description: Re-maps a number from one range to another. That is, a value of fromLow would get mapped to toLow, a value of fromHigh to toHigh, values in-between to values in-between, etc. Does not constrain values to within the range, because out-of-range values are sometimes intended and useful. The constrain() function may be used either before or after this function, if limits to the ranges are desired.
Grove Beginner Kit For Arduino® The function is used to write an analog value between 0 - 255 a PWM pin. analogWrite() can only be used for PWM pins. The new mapping data in the previous statement can be output to ledPin to lighten/dim the LED.
