Raspberry Pi Raspberry Pi is a mini computer based on an ARM processor. Since many different operating systems can be installed on this mini-computer, it can be used in various robotics, programming, and electronics projects. There are different types and versions of this mini-computer. The newest versions are Raspberry Pi 3 Model A+ and Raspberry Pi 3 Model B+. More than 19 million Raspberry Pi boards have been sold around the world until now. Raspberry Pi 3 Version B+ Specification:...

Introduction Would you like to unlock the full potential of a sensor? Do you enjoy challenging your limits? Well, that’s exactly what the HR202L sensor offers! HR202L is a variable capacitor with a non-linear logarithmic behavior, whose values depend highly on the ambient temperature. Whether you're new to Arduino or have been using it for a while, this guide will provide you with everything you need to get started with the HR202L sensor. By following clear instructio...

CJMCU-0201 Double Touch Sensor Features A touch sensor is a type of switch that only has to be touched by an object to operate. Touch sensors work completely similar to a switch. This sensor has two separate pads and can be used as two separate switches. Note When this switch is subjected to touch, the output voltage will be HIGH, otherwise it is LOW. Note The output current is very low (about 40 mA). If you want to connect a higher current device to this switch, you must add a rela...

ULN2003 Stepper Motor Driver Features We usually use stepper motors when we need precise control of the motor shaft. These motors can be used in robot arm, 3D printers, CNC machines, etc. 28BJY-48 is a kind of stepper motor. In full step mode, these motors have a 1 to 64 speed reduction gearbox and eachfull 360 degree rotation consists of 32 steps. The ULN2003 driver is commonly used to control these motors. ULN2003 IC consists of 7 pairs of Darlington transistors, each pair can withstand 500mA and 50V. Th...

Single Axis 1:120 Gear Motor Features If you work in electronics and robotics field, you have come across DC motors at least once. These motors are one of the most widely used elements in electronics and robotics. These motors convert direct current electrical energy into mechanical energy.An external source provides power for the stator of these motors. As a result, the current flowing through the stator creates a uniform field under the poles. Of course, permanent magnet can supply the stator field, ...
