In one of our previous tutorials we did an introduction on how to use the Nokia 5110 LCD  with the Arduino, the tutorial covered displaying texts with different fonts etc. For this tutorial, we are taking things a little bit further and will be working through the display of customized...

Nowadays, there is a lot of technology that implements wearables in fashion, medicine, worker safety, accessories and much more. Many wearables are coupled with uncomfortable charging cables that are irritating for users to handle, some even have big batteries that make wearables a...

Pressure sensors are used today in many fields, such as automotive industry, touch screen devices, aviation and biomedical instrumentation, many of these applications require precise and accurate measures. Many times, this can not be achieved because of the limitations of the sensors...

Hobbyists, makers, students and pretty much everyone who works with electronics has encountered the same issue, not having a handy power supply to test their projects. Usually, controllable power supplies are big, expensive and for some people difficult to access, and most small power...

Recently Californian startup Chirp Microsystems officially announced two discrete ultrasonic Time-of-Flight (ToF) sensors, the CH-101 and CH-201, with maximum sensing ranges of 1m and 5m, respectively. Both chips have a 3.5x3.5mm package and they are powered by same ASIC or...

MATRIX Voice is a"Voice Recognition" development board, designed for the Raspberry Pi or Stand-alone with ESP32 (WiFi/BT/MCU) MATRIX Voice is an open-source VOICE RECOGNITION platform consisting of a 3.14-inches in diameter dev board, with a radial array of 7 MEMS microphones connected...

STMelectronics introduces a super tiny two-axis gyroscope (L20G20IS), a Micro-Electro-Mechanical system (MEMS) designed for the optical image stabilization for Smartphones with less energy consumption compared to its predecessor (L2G2IS). A gyroscope, or gyro for short, adds an...

  The transistor revolutionized the field of electronics, and paved the way for smaller and cheaper radios, calculators, and computers, among other things since its very first practically implemented device as a point-contact-transistor invented in 1947 and...
