Most Arduinos have an on-board LED you can control. On the UNO, MEGA and ZERO it is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN is set to the correct LED pin independent of which board is used. If you want to know what pin the on-board LED is connected to ...
ESP32 Cam includes two power pins; 5V & 3V3, so this module is powered through the 3.3V/5V pins. The VCC pin of this module usually outputs 3.3Volts from the on-board voltage regulator but it can be configured to 5V output with the Zero-ohm link close to the VCC pin. GNDis the g...
The Intel® Galileo is a single-board computer developed by Intel® designed for embedded systems and DIY electronics projects. It includes a range of features, including ethernet and Wi-Fi connectivity, a range of I/O pins, and compatibility with Arduino software. ...
Use the right finger to touch both the gate & drain pins so that we can observe that the pointer of the analog multimeter will turn aside to the center range of the scale of the meter. Take away the red probe of the multimeter & also the right finger from the source pin of MOSFET t...
An example of a software-based keyboard encoder is the Arduino Keyboard Library, which allows an Arduino board to act as a USB HID (Human Interface Device) keyboard. The library uses the Arduino pins to connect to the keyboard matrix and provides functions to read the key states and send ke...
When it comes to distance sensors, there are many different types; ultrasonic, IR proximity, laser distance, etc. and selecting the right one for your next Arduino or Raspberry Pi project could be a tough task to handle. Hence, today we’ll be looking at the plethora of distance sensors,...
The SOJ packages have J-bend leads like PLCC, but they have pins on only two sides. This package is a hybrid of SOIC and PLCC and combines the handling benefits of PLCC and space efficiency of SOIC. SOJs are commonly used for high density (1, 4, and 16 MB) DRAMSs. ...

5V 1A switching power supply onboard. 11 digital input/output pins, all pins have interrupt/pwm/I2C/one-wire and a micro-USB connection. How to get it started in for Arduino: - Setup driver Before you use mini D1 boards, you need set up CH340g driver. ...
Both the pins like Trig & Echo allow the Arduino board to interact with the ultrasonic sensor. Here, voltage & GND pins deliver the power to the sensor & the Echo & Trig pins allow it to transmit & receive data through the Arduino board. ...
