[Super Starter Kit]
RexQualis Inc. is a professional manufacturer of electronic components products, which is engaged in development, design, production and sale. We aim to help our customers implement the creative idea and product prototypes quickly. This makes programming and electronics enthusiasts easier to get started and introduced innovative open source products.
This starter kit contains a large number of components and sensors that allow any electronics and programming to learn. We offer a detailed tutorial in which the basic settings compatible with Arduino IDE, the operating principles of the sensors and the simple program are introduced. For beginners, even if you have no electronic knowledge, simply follow our easy-to-follow tutorials and step by step you will find that it is more fun than you ever expected. For advanced users such as laboratory engineers, teachers. pencpencils and manufacturers You can use it to build cost-effective scientific instruments, prove principles of chemistry and physics or start programming and robotics. It is also a good choice and a perfect gift for your family, obsessed with electronics, programming or robotics so you can learn and grow together.

The REXQualis controller card is based on Arduino UNO R3.100% and is compatible with Arduino IDE. |
Pins and wires on some parts such as LCD16502 and motors have been pre-soldered, which is very convenient and saves time. |
We have updated and optimised some modules. Diodes have been added to prevent the positive and negative electrodes from inserting errors and burning the motherboard. By adding the indicator light, we can clearly see if the module is working or not. |
REXQualis Super Starter Kits come with a 9V 1A power supply to replace a 9V battery which is an existing safety threat. |

LCD1602 display moduleIn this project, you will learn how to connect the LCD display to the microcontroller board and display what we type. In addition, we can use the potentiometer to control the brightness of the screen. The LCD1602 module is an LED backlit display and can display two lines of up to 16 characters in each line. You can see the rectangles for each character on the display and the pixels that each character consists of. The display is only white on blue and is used to display text. The REXQualis LCD1602 module comes with a pin head and does not need to be soldered by yourself. Then you can simply align the display with the top of the peg board to identify the pins. |
Stepper motor controlled by IRIn this project, you will learn a fun and easy way to control a stepper motor remotely with an IR remote control. The 28BYJ-48 is a small 5 volt gear step motor which seems to be widely used to control things such as automated blinds and air conditioners. And it comes with an ULN2003 stepper motor driver board that allows you to easily control the 28BYJ-48 stepper motor from a microcontroller. The IR sensor is directly connected to the microcontroller board because it consumes almost no power. When fully connected, you can control the stepper motor via the IR remote control. |
DC motor with L293D and relayIn this project, you will learn how to control a small DC motor using a L293D transistor and relay via a microcontroller board. The L293D transistor is a very practical chip that can control two DC motors independently. In this experiment, only half the chip is used. Relays are generally used to switch smaller currents in a control circuit and normally do not control electricity consuming devices, except for small motors and solenoid coils that consume low amps. Nevertheless, relays can "control" larger voltages and amps by gain effect, as a small voltage applied to a relay coil can cause a large voltage to be switched from the contacts. |
