ESP32-C3 is a single-core Wi-Fi and Bluetooth 5 (LE) microcontroller SoC, based on the open-source RISC-V architecture. It strikes the right balance of power, I/O capabilities and security, thus offering the optimal cost-effective solution for connected devices. The availability of Wi-Fi and Bluetooth 5 (LE) connectivity not only makes the device’s configuration easy, but it […]
The Tower Pro™ Micro servo S9 (SG90) motor is one of the most popular servo motors at the moment. This servo motor has a torque of up to 1.56 kg*cm, which makes it easy to move all kinds of sensors, camera’s or even small robots. Tower Pro™ Micro servo S9 (SG90) Let’s take a look

In this blog we look at the Sensirion SHT3x Temperature/Humidity sensors are some of the finest & highest-accuracy devices you can get. And, finally we have some that have a true I2C interface for easy reading. The SHT30 sensor has an excellent ±2% relative humidity and ±0.3°C accuracy for most uses. Unlike earlier SHT sensors,

Servo motors can be found in robotic arms, cameras, lathes, CNC machines, printing presses and other engineering applications where precision and repetitive motion are required. Servo motors often consist of DC motors that use feedback mechanisms to move from one position to another with great precision. The inexpensive servos found in maker projects use potentiometers

Look into any commercially made electronic device these days, and it is filled with tiny components (SMD). Rather than using traditional components with wire guides. These components are mounted on the surface of the boards, and many are minuscule. This technology is known as Surface Mount Technology, SMT and SMD components. Virtually all equipment commercially

What’s up fellow makers, today we do another little product review. I ordered and received a package from Omnifixo, and I’m quite keen to see what’s inside. All right, so let’s take a look. Omnifixo makes a “third hand”, perhaps you know those cheap third hands for soldering with the crock clams. Perhaps you know
Year 2021 will go down in history as one of the worst in recent memory. It has been pretty eventful, to put it lightly. With the pandemic being the dominant problem, punctuated by a lot of calamities, the year felt like it came by fast and slow at the same time. For most of us,

For those that starting with the Node MCU ESP modules, I have made some pinout diagrams, their functions and how to use them. The Node MCU ESP8266 12-E chip comes with 30 GPIO pins. All GPIO’s are exposed on all ESP8266 development boards, some GPIO’s are not recommended to use, and others have very specific

In this blog we look at the BH1750 light intensity sensor breakout board with a 16 bit AD converter built-in which can directly output a digital signal, there is no need for complicated calculations. This is a more acurate and easier to use version of the simple LDR which only outputs a voltage that needs
