ZMCT102W Features The ZMCT102 transformer has a turns ratio of 2000:1, a maximum input current of 5A, and a maximum output current of 2.5mA. In addition, the hole in the transformer, through which the wire passes, has an inner diameter of 5mm.ZMCT102 transformer measures the current based on the magnetic field generated by the current flowing through the wire at the center of the transformer. It then provides an output voltage value that is proportional to the current.In this tutorial, we will cover t...

Overview There are two main ways to program the STM32F103C8T6 module, also known as the STM32 Blue Pill: • Serial and USB to TTL converter • ST-Link Tip Sometimes you might find out that the STM32 module you have is not original. And it can’t be programmed through serial. Therefore, we suggest you use ST-Link to program the STM32 Blue Pill. Required Materials Hardware Components STM32F103C8T6 Blue Pill × 1 ST-Link/V2 Programmer × 1 Male to Male Jumper Wire × 1 Software Apps Ar...

Overview A potentiometer is a device that can change its resistance by moving a contact along a fixed resistor. It has three terminals: one connected to each end of the resistor and one connected to the movable contact. By adjusting the position of the contact, the potentiometer can divide the input voltage into different output voltages [Read more in Wikipedia]. Potentiometers work by creating a voltage drop across the resistor that is proportional to its length. For example, if the input voltage is 10...

GY-25 Module Features The GY-25 sensor module is a high-resolution 3-axis sensor based on the MPU6050 sensor. It includes a 3-axis gyroscope and a 3-axis accelerometer, all in the MPU6050 sensor chip. The GY-25 module also has a microcontroller called the 32F030F4P6. Its role is to process and convert data from the MPU6050 sensor to obtain the angle value. The microcontroller and Arduino board communicate with the GY-25 module through the UART interface. In addition, the GY-25 module has an I2C interface fo...

Installing New Library in PlatformIO, Step 2: Finding Library Location Using ...

Introduction The KY-028 module contains a thermistor sensor that measures the ambient temperature. The resistance of the thermistor varies inversely with temperature. In addition, the analog and digital output pins provide the sensor's data. When the value measured by the sensor exceeds the threshold, the digital pin goes HIGH, lighting up the LED on the module. Tip You can adjust the digital output threshold using the blue potentiometer on the module. KY-028 Pi...

Introduction RFID, which stands for radio frequency identification, enables data reading and identification of unique tags using radio waves. RFID modules operate on specific frequencies, requiring tags that match the reader module's frequency. In this article, we will design and implement a simple identification system using a 125KHz RFID module and the Wiegand protocol. Tip While the RFID module used in this article shares similarities in shape and structure with the RDM6300 RFID reader m...

TM1637 Display Module Features The 4-digit 7-segment display module—with a TM1637 driver—can display various outputs. It communicates with the microcontroller using only two pins—SCL and SDA. The chip of the TM1637 Display Module allows us to scan the 8*2 keypad. This module also offers eight different modes to adjust the display background light. In addition, it operates within a voltage range of 3.5 to 5V. Below, you can download the TM1637 driver datasheet.  [wpdm_package id='26859'] TM163...

Introduction Analog-to-digital converters (ADCs) convert analog data into digital format. The 16-bit ADS1110 module offers good accuracy for measuring analog data with the microcontroller. In this tutorial, we will interface an ADS1110 module with Arduino. The communication between the module and the Arduino board is done by the I2C protocol. Tip: The built-in 10-bit ADC of Arduino has a lower accuracy compared to the ADS1110 module. Therefore, to measure the anal...
