Preface
No circuit
Installing the Arduino IDE and its libraries, and opening the serial monitor. Here the editor, the compiler and the libraries are already in the browser.
1
Blinking LED
Runs here
An LED and a 220 ohm resistor on pin 8, on for a second and off for a second.
Open in the editor Blink an LED on pin 8
2
RGB LED
Runs here
Red on pin 3, green on 5 and blue on 6: analogWrite mixes red, green, blue, white and purple.
Open in the editor RGB LED on pins 3, 5 and 6
3
Controlling an LED by Button
Runs here
Two buttons with the internal pull-ups: the one on pin 9 turns the LED on pin 5 on, the one on pin 8 turns it off.
Open in the editor Two buttons, one LED
4
Active buzzer
Runs here
An active buzzer on pin 12 sounds whenever the pin is HIGH, so the sketch only chooses when.
Open in the editor Active buzzer
5
Passive Buzzer
Runs here
A passive buzzer on pin 12 plays the eight notes of a scale with tone().
Open in the editor Passive buzzer scale on pin 12
6
Eight LED with 74HC595
Runs here
Eight LEDs from three pins through a shift register, data on 2, latch on 4 and clock on 5: one light runs along the row.
Open in the editor Eight LEDs on a 74HC595 (pins 2, 5 and 4)
7
Photoresistor
Runs here
A photoresistor on A0 sets how many of eight LEDs light, through a 74HC595 on pins 9, 11 and 12.
Open in the editor Photoresistor bar graph on a 74HC595 (pins 9, 12 and 11)
8
74HC595 And Segment Display
Runs here
One seven-segment digit through a 74HC595 (data 8, latch 9, clock 10), counting down from D to 0.
One 220 ohm resistor on the common pin stands in for a resistor on every segment.
Open in the editor One-digit countdown on a 74HC595 (pins 8, 10 and 9)
9
Four Digital Segment Display
Runs here
A four-digit display on the same 74HC595 pins, every digit on, stepping through the hex digits.
The kit’s sketch shows 1 to F, two seconds each; this one steps through 0 to F twice a second.
Open in the editor Four-digit display on a 74HC595 (pins 8, 10 and 9)
10
Tilt Ball Switch
Runs here
A tilt switch read with analogRead on A5: upright, the LED on pin 8 lights; tip it and the LED goes out.
Open in the editor Tilt switch on A5 lights the LED on pin 8
11
Ultrasonic Sensor Module
Runs here
An HC-SR04 with TRIG on 12 and ECHO on 11, read with the SR04 library, prints centimeters.
Open in the editor Ultrasonic distance on pins 12 and 11
12
Analog Joystick Module
Runs here
X on A0, Y on A1 and the press switch on pin 3 with its pull-up, printed to the serial monitor.
Open in the editor Joystick module: A0, A1 and pin 3
13
Membrane Switch Module
Runs here
A 4x4 keypad with its rows on pins 9 to 6 and its columns on 5 to 2: the Keypad library prints each key.
Open in the editor Membrane keypad on pins 9 to 2
14
DHT11 Temperature and Humidity Sensor
Runs here
A DHT11 module on A0, read with no library: the sketch times each of the 40 bits itself and prints humidity and temperature.
It prints at 9600 baud, where the kit’s sketch uses 19200.
Open in the editor DHT11 on A0, read with no library
15
IR Receiver Module
Runs here
An IR receiver on pin 11 decodes the remote’s buttons and names each one on the serial monitor.
The kit’s sketch names some keys differently (POWER, MODE, VOL+). The simulated handset sends the same codes, and the decoder names them by its own labels; the digits match.
Open in the editor IR decoder
16
Controlling Stepper Motor With Remote
Runs here
An IR receiver on pin 12 and a 28BYJ-48 on pins 8 to 11: one remote button turns the shaft a whole turn, another turns it back.
The kit’s sketch listens for the codes 0x40 and 0x43, which are >>| and >|| on the simulated remote. The stepper runs from the Uno’s 5 V here, not the breadboard power supply.
Open in the editor Remote stepper, a whole turn a press
17
Servo
Runs here
An SG90 on pin 9 swings across its range and back with the Servo library.
Open in the editor Servo sweep
18
LCD Display
Runs here
A 16x2 LCD on eight data lines (pins 3 to 10) with RS on 12, RW on 11 and E on 2, driven with no library.
The contrast knob is left out: the simulated display is always readable, so V0 goes to ground.
Open in the editor LCD1602 in 8-bit mode on pins 2 to 12
19
Thermometer
Runs here
A thermistor on A0 and the LiquidCrystal library on pins 7 to 12: the temperature in degrees on the LCD.
The contrast knob is left out: the simulated display is always readable, so V0 goes to ground.
Open in the editor Thermistor thermometer on an LCD (pins 7 to 12)
20
DC Motor Control
Runs here
An L293D runs a motor: speed on pin 5, direction on pins 3 and 4.
The motor runs from the Uno’s 5 V here; on the bench the lesson powers it from the breadboard power supply module.
Open in the editor DC motor on an L293D (pins 5, 3 and 4)
21
Relay
Runs here
The L293D on the same pins drives a relay’s coil, and the relay switches the motor.
The motor runs from the Uno’s 5 V here; on the bench the lesson powers it from the breadboard power supply module.
Open in the editor Relay switched by an L293D (pins 5, 3 and 4)

FAQ

Questions about this page

Is this made by REXQualis?

No. Mokxi is independent and is not affiliated with REXQualis. The page follows the kit’s lessons so you can use the two side by side; the circuits, sketches and explanations are Mokxi’s own.

Do I need the kit?

No. Every lesson that runs here runs in the browser, so you can try them before you buy a kit, or keep going while a part is missing or broken.

Is the code the same as in my manual?

The pins and the parts are the same, and the sketches use the same libraries where the kit does. The code itself is written for this page, with comments that explain each step, so it will not match the manual line for line.

What do "with a change" and "coming soon" mean?

A lesson marked "with a change" runs, but something differs from the kit, and the note under it says exactly what. "Coming soon" means we cannot simulate that lesson yet, and the note says why. We do not mark a lesson as running unless it does.

Is it free?

Yes. Every lesson on this page opens with no account. A free account saves your own copies of the circuits.
