004 - MakeCode MicroBit: Brickcell Ultrasonic HCSR04

The Ultrasonic Sensor is a device that uses ultrasonic sound waves to measure distance and/or detect an object. They are a type of proximity sensor that works on the principle of echolocation, similar to how bats and dolphins navigate in the dark. These sensors emit high-frequency sound waves (ultrasonic waves) that are beyond the range […]

003 - MakeCode MicroBit: Brickcell NTC Temperature

A Negative Temperature Coefficient (NTC) temperature sensor is a type of resistor that exhibits a decrease in electrical resistance as its temperature increases. In other words, the resistance of an NTC thermistor decreases as the temperature rises, and it increases as the temperature decreases. This behavior makes NTC thermistors suitable for various temperature-sensing applications. From […]
