This post reviews a magnetic reed switch sensor module. There are many of these available on the internet and all work similarly using a basic reed switch. Here I review and test the sensor and provide code to use it.
This post reviews the Arduino Starter Kit. This is an ideal kit for a beginner in electronics and embedded systems or for someone wanting to learn how work with an Arduino. Here I look over what you get in the kit and the projects it provides.
The TTP223B Capacitive touch sensor is a button type sensor that allows you to detect when it is being pressed. In this post I review the sensor and provide code and a wiring diagram to use such a sensor.
This post is a review of the “Light Intensity Sensor Module 5528 Photo Resistor” and includes code and images to use the sensor. There are a couple variants of this light sensor sold by different companies but all have similar components and designs. This model is sold by HiLetgo CN and is available on amazon (link below).
