DS1302 RTC Module Features for Accurate Timekeeping The DS1302 real time clock module is a cheap module with high accuracy that can be used in different projects. This RTC module provides seconds, minutes, hours, day, date, month, and year information. In this module, date is set automatically based on whether the month is 29, 30 or 31 days and also it is leap year or not. (That's only valid until the year 2100) Note Please be aware that this module does not use I2C communication. Interfacing the DS1302 wi...

Piezoelectric Vibration Sensor Features Piezoelectric vibration sensor is based on piezoelectric ceramic sheet. This sensor uses piezoelectric ceramics to generate vibration. When the piezoelectric ceramic piece vibrates, an electrical signal is generated.This sensor has two digital and analog outputs. The greater the vibration intensity, the higher the analog output voltage. Vibration amplitude sensitivity can be adjusted by the potentiometer. Note When the sensor vibrates, the digital outpu...

TCRT5000 IR Sensor Features This sensor which is mostly used for line tracking, works like motion detection sensors. It is based on TCRT5000 IC. The TCRT5000 is a sensor that emits infrared light continuously. If the transmitted wave is not reflected or is reflected very poorly, the output will be LOW. If you put an object in front of this sensor, the output becomes HIGH. Note Black color absorbs the transmitted IR radiation and reflects it very poorly. So the output will be LOW if there is ...

BT06 Bluetooth Serial Module Features Bluetooth modules are a type of wireless communication modules that can be added to a project through serial or SPI communication protocols.The advantage of using Bluetooth modules is that they are easy to set up and use.The BT06 module uses serial protocol for communication. Note All Bluetooth modules that use serial communication protocols, support AT Commands, which are listed in the datasheet of each product. Download th...

LoRa SX1278 Transceiver Module Features Electronic devices need to be connected wirelessly in so many cases. In these cases, Radio Frequency or RF equipments are used. RF modules include all radio waves that can travel different distances and reach the receiver according to their frequency and amplitude. LoRa is a popular technology that is perfectly suitable for IoT projects with long distance communications. This module is an Ai-Thinker technology module which also produces ESP32 series. This module...

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...

Introduction If you are familiar with programming for STM, ESP, and RP2040 microcontrollers, you must have heard of MicroPython programming language.To write code in this language, you need specific software. One of the most common integrated development environments (IDE) designed for programming in Micropython language is Thonny - MicroPython software.In this tutorial, we will learn how to work with this software. Therefore, at the end of this tutorial, you should be able to write a simple code in Mic...

What Is Reed Switch? The Reed Switch is a magnetic switch that has two (on and off) switching modes, like a normal switch. The two pins are connected to each other by being in a magnetic field (for example, close to the magnet) and are disconnected by leaving that field. These switches are used in open/close door detection sensors, seat belt sensors, collision detection sensors, etc. Tip Some magnetic switches are Normally Close. That is, when they are not in a magnetic field, the two pins are co...
