IR sensors for temperature detection are extremely easy to set up and use with our microcontrollers, only 4 wires needed and two of them of for power! If you’re a video kind of person then here’s the accompanying video, otherwise read on below for more textual instructions! Affiliate links Various […]
An intro to using the ESP32 Camera module. Very simple to set up and use, this example uses the is the AI Thinker Module. Camera’s are ridiculously cheap and small nowadays and with small power consumption you could use them from battery power for many hours. The video below takes […]
The video below goes through the details, underneath the video you will find the sample code, a circuit diagram and an affiliate parts list. The MPU6050 is a versatile unit that can measure its orientation and it’s acceleration in all three dimensions. However did have difficulty in finding a user […]
The video covers using PIR (Passive InfraRed) sensors with an Arduino. These are simple movement sensors and although libraries are available they are not required to work with these devices. The sample code shown in the video is shown below.
This project will allow an ESP32 to access online weather forecasts for display on an E-Paper display, running on batteries with an always on display. Cheap Lithium Ion batteries will give around 1.5 to 2 weeks service, better quality or better capacity will give you potentially several weeks. The video […]
The BME280 based pressure and temperature sensors have an amazing accuracy for their price point (around 5USD, 5Euro, 5GBP or cheaper!) and they are incredibly easy to connect up and use. Both I²C or SPI busses are usually supported. Below is the one similar to those that are readily available. […]
The BMP280 based pressure and temperature sensors have an amazing accuracy for their price point (around 1$USD, 1Euro, 1GBP or cheaper!) and they are incredibly easy to connect up and use. Both I²C or SPI busses are usually supported. Below is the one similar to those that are readily available. […]
This article should be used in conjunction with the video below; In this article you will discover how to get your ESP32 to monitor and report on it’s own battery level. Handy for battery powered projects. All your require are two resistors (anything from 1K upwards, I generally use 10K). […]
If you haven’t read the previous article (part 1) then I suggest you follow this link otherwise this write-up won’t be of much use! In the last article we got the screen and the MAX30100 pulse/oximeter up and working. In this one we’re going to add everything else! A video […]
This article supports a video on the build of the Star Trek Sick Bay project (external you tube link). You should watch that video as well as this article as it contains information not mentioned below. This is part one of a two part write up. Doing all this on […]
