		LED LIGHT (DIGITALY)

The LED lights up and goes out at half-second intervals.

Mega_prog_01.zip


		LED LIGHT - MICRO SWITCH (DIGITAL)

Pressing the switch, the LED lights up.

Mega_prog_02.zip


		LED LIGHT (ANALOGUE)

The program slowly increases the brightness of the LED.

Mega_prog_03.zip


		LED LIGHT - MICRO SWITHCH (ANALOGUE)

By pressing the button, the bright LEDs light up.

Mega_prog_04.zip


		PHOTO SENSOR - LED LIGHT (DIGITAL)

The LEDs light up when the PHOTO sensor is sufficiently illuminated.

Mega_prog_05.zip


		PHOTO SENSOR - LED LIGHT (ANALOGUE)

The LEDs light up depending on the value read by the PHOTO sensor.

Mega_prog_06.zip


		DC MOTOR (DIGITAL)

The DC motor starts rotating in one direction for 100 ms. It stops for 2 seconds and then repeats the action.

Mega_prog_07.zip


		DC MOTOR - ONE WAY ROTATION (DIGITAL)

By pressing switch, the DC motor starts to rotate in one direction.

Mega_prog_08.zip


		DC MOTOR - TWO WAYS ROTATION (DIGITAL)

Pressing the switch A and B, alternates the direction of rotation of the DC motor (both directions).

Mega_prog_09.zip


		DC MOTOR - SPEED CONTROL (ANALOGUE)

Program, changes the rotation speed of the DC motor. Lower rotation speed, usually means lower engine power.

Mega_prog_10.zip


		IR SENSOR (DIGITAL)

Depending on the IR sensor readout, the LEDs light up. The white surface gives the reading 1 and the black (line) 0.

Mega_prog_11.zip


		IR SENSOR (ANALOGUE)

By analogous reading of the IR sensor, a white surface can be detected at a distance of several centimeters.

Mega_prog_12.zip


		HEAT SENSOR (ANALOGUE)

By heating the thermal sensor to a certain temperature, the LED lights up. We heat the thermal sensor with light bulb.

Mega_prog_13.zip


		MAGNETIC SENSOR (DIGITAL)

A magnetic sensor detects a magnetic field. By approaching the sensor to a magnetic field (permanent or electromagnet), the LED lights up.

Mega_prog_15.zip


		COLOR SENSOR - COLORS

The color sensor reads colors as values (analog). According to the apparent color value, a certain color of the LED lights up. The readings are VERY dependent on the conditions (illumination) and may vary even though the color patterns are the same

Mega_prog_16.zip


		COLOR SENSOR - BLACK LINE

The readings for white and black are usually different enough, so that with the help of two color sensors we can make robot car that follows the black line.

Mega_prog_17.zip


		ULTRASOUND SENSOR (DIGITAL)

With the help of an ultrasonic sensor we can detect an object when it is at a distance less than the one set in the program (the LED lights up). If the object is at a greater distance, the program will not register it.

Mega_prog_18.zip


		ULTRASOUND SENSOR (ANALOGUE)

Using the ultrasonic sensor, we can measure the distance to the object in front of the sensor. Depending on the sensor, larger or smaller maximum distances can be read. The LED illuminates less when the distance from the sensor to the subject is smaller and vice versa.

Mega_prog_19.zip


		SERVO MOTOR

Servo motor control example. Turning the servo motor lever by 45 and 90 degrees.

Mega_prog_20.zip


		I2C COMMUNICATION

Mega_prog_21.zip


		RX - TX COMMUNICATION


		ENCODER MOTOR - STEP - LESS PRECISE

We only count impulses (value 1). So we need to put a little pause to prevent multiple sensor readings. This method is less precise. The number of impulses we will count depends on the program itself. If the program only controls the engine, or still performs other operations. In the second case, especially at higher engine speed, the program will not be able to read all pulses.

Mega_prog_23.zip


		ENCODER MOTOR - HALF STEP - BETTER PRECISION

We count the state changes (values 1 and 0). This method is better accurate than the previous one (STEP). The number of impulses we will count depends on the program itself. If the program only controls the engine, or still performs other operations. In the second case, especially at higher engine speed, the program will not be able to read all pulses.

Mega_prog_23.zip


		COMMUNICATION - NRF24L01

Two Arduino MEGA moduls with NRF24L01 modul. Sending and reciving data. Program samples are for two LEDs (red and green) and two switches. If you use Mega-F5, not forget to change numbers of INPUTs on which are switches connected (SEND program).

Mega_prog_25.zip


		I2C - LCD 2 x 16

Display data on LCD. We use the LCD library to communicate with. As an example, we made a timer, showing minutes and seconds.

Mega_prog_32.zip


		STEP MOTOR

Example of stepper motor control in FULL step mode and HALF step mode. The speed is adjusted with the delay command. For this example, we used a motor that runs at 5V and supports a maximum of 180 steps for full speed. A step counter should be placed in the program for accurate control. Stepper motors are big consumers and care should be taken not to draw too much electricity as the drivers will get very hot. We use a voltage of 5V to power the shield and Mega.
