Testing Out an Ultrasonic Sensor (The Posh Way)

Testing Out an Ultrasonic Sensor (The Posh Way)

This week we’ve got a lesson where we’ve got to test out an ultrasonic sensor using an Arduino Uno board. We’re going to be doing something similar in our lesson to what we did in the post “Tuning The Distance of an IR Sensor Using Arduino” that I wrote last week in class; only this time (because I’m not in class and I can think straight) I want to integrate the sensor with a thermostat using a thermistor (because the...Read more

Tuning The Distance of an IR Sensor Using Arduino 🧶

This post is going to explore the process of connecting a sensor up to an Arduino circuit, to analyse the data and then come up with a way of calibrating the sensor for a specific task. When using sensors, we need to work out what the sensor values actually mean. In this instance we’re being given numbers (off the sensor) like 570 for a distance of 4cm or 525 at a distance of 26cm. We need to find how to...Read more
