Assembling and Using the Educational Programming Board

The educational programming board is a versatile and open-source platform designed for educational purposes. It is Based on the ESP Wi-Fi module and comes with four RJ25 Jack ports for easy module connectivity. The motherboard not only enables the control of dual motors and a servo motor but also features source codes created by the popular chat GPT.

To transform circuit designs into durable prototypes, printed circuit boards (PCBs) are preferred. These PCBs offer long-term stability and durability for electronic circuit prototypes. Surface mount device (SMD) components are also utilized in the board design, affecting both the size and cost of the board.

To ensure accurate solder paste application, solder stencils are commonly used during the assembly of SMD components. The stencil is placed on the printed circuit board, and solder paste is applied and spread using a spoon and spatula. After applying the solder paste, the required components are placed on the designated spots indicated by a designator or footprint reference.

Soldering, either with a hot plate machine or a HAND soldering iron, is the next step in the assembly process. The soldering machine heats and melts the solder paste, fixing the components in place once it cools. The components are then completely fixed, and any additional components such as headers and RJ25 Jacks can be easily soldered with a soldering iron.

Once the motherboard is assembled, the next stage involves soldering the modules. These modules include a potentiometer, humidity and temperature sensor, buzzer, and LED. The locations of these components in the modules are specified by designators. It is important to ensure the correct placement and soldering of these modules.

Introducing chat GPT, a popular ad tool that offers incredible results. With chat GPT, it is possible to generate code for various functionalities, starting with generating a simple blink code for the LED and buzzer. By specifying the pins to which the modules will be connected, the generated code can be copied and pasted into the editor. Upon uploading the code, the modules can be plugged into the designated pins to test their functionality.

Moving on to servo motor control, chat GPT can be used to generate code for controlling a servo motor with a potentiometer connected to its analog pin. By adding the servo library and using the map function, the code can be generated successfully. After uploading the code to the board, the servo motor can be tested with the potentiometer.

The humidity and temperature sensor module is next in line. By specifying the pin to which the module is connected and using the suitable library, chat GPT can generate code that displays the sensor values via the serial monitor. Upon uploading the generated code to the board, the humidity and temperature module successfully performs its function, providing accurate sensor values.

Finally, chat GPT can also generate code for DC motor control. By specifying the 8833 driver for motor control and defining the pins for forward and backward movements, chat GPT can produce code that uses pulse width modulation (PWM) for motor control. Some adjustments may be required, such as fine-tuning the sleep mode and defining motor speed values. The code can then be uploaded to the board, allowing efficient control of the DC motor.

The educational programming board is equipped with a 1117 5 volt regulator, enabling it to be powered by an external power source. The motor movement LED indicators on the motherboard ensure that the motor is running successfully. With all the components and code working seamlessly, the educational programming board offers a range of possibilities for educational projects.
