When you think of Arduino projects, your mind likely goes straight to RFID door locks, weather sensors, or automated plant watering systems. While these are undeniably pretty cool projects, you might ...

Fascinated with electronic projects and want to build your own? Arduino boards can most definitely help with that. These microcontroller boards are designed to send and receive data to and from the ...

MakerFabs sent the package to me from China. Inside the package, there were 4 sets of the MaUWB_DW3000 with STM32 AT Command. Each set contains the module, a 3.7V 600mAh battery, and 2 pieces of ...

Hello, I’m excited to review the ESP32 display modules and HMI touchscreens from Elecrow with sizes ranging from 2.4 to 7.0 inches. For this review, Elecrow kindly provided me with both 3.5-inch and 7 ...

The following image shows the circuit diagram of the Smart Dustbin with Arduino. It is a very simple design as the project involves only three main components (Ultrasonic sensor, IR sensor and Servo ...

Last time, we’ve used a logic analyzer to investigate the ID_SD and ID_SC pins on a Raspberry Pi, which turned out to be regular I2C, and then we hacked hotplug into the Raspberry Pi camera code with ...

I purchased one of each of these cheap sensors recently from aliexpress for testing purposes. Compared with the ubiquitous HC-SR04 (*), I liked the idea of having a combined emitter/receiver, i.e.

The non-contact liquid level sensor uses the sensing capacitance of water to detect the presence of liquid approaching the sensor. The sensor has a specific static capacitance due to the distributed ...

Infrared line tracker modules hardly need an in-depth explanation as they’re very familiar to most electronics and robotics hobbyists. In this post I’ll discuss a popular and cheap infrared line ...
