Charging and discharging of capacitors A capacitor is a component that stores electrical energy in the form of an electric field. Assemble the capacitor and resistor on the breadboard, as shown below. When you press the … more
You can measure the voltages between 0 and 3.3V with micro:bit. Connect a 4.5V battery or USB power source to the micro:bit (3V batteries cannot be used). Do not measure excessively high voltages. It can damage … more
We printed a plastic frame to use Javalab Logger (Microbit data logger system) conveniently. Microbit, expansion board, and batteries are integrated into one frame, making it more convenient. We provide the 3D printing data below. Here’s … more
Ultrasonic rangefinder This sensor measures distance using the return time after ultrasonic waves are emitted. Please use the HC-SR04P (or HC-SR04+) sensor for 3V and 5V. Please note that 5V-only HC-SR04 will not operate. Connect the … more
