Let’s build an IoT device that sends flame sensor data to SAMI using SAMI’s WebSockets. The IoT device consists of an off-the-shelf sensor, Arduino UNO and Raspberry Pi. In this implementation, a Simple Manifest is used to create a new device type quickly. Then you can easily connect the IoT device to SAMI, and start […]

Pssst – want some high tech protection for your home office, or a secret lock for your “workshop” (ok, you got me, it’s actually a dungeon/gaming room) that the kids won’t be able to figure out? We’ve got you covered. Let’s build a DIY smart lock that automatically detects when you’re there, and locks when you’re not.

All right this is the review on the next two lessons on linear hall sensors. Lesson 02 uses an analog linear hall sensor and an analog to digital conver IC ADC0832. The lesson 03 uses a linear hall sensor with added comparator, which allows some sensitivity tuning of the sensors by adjusting the potentiometer. The

In this instructable we will learn how to make a simple yet effective baby monitor that detects and alerts you whenever the baby is crying. We used Philips Hue as an alert system but you can choose a different item or channel to get notified. Besides, while commercial baby monitors will cost you a couple

With some effort I have found that controlling two servo motors to allow a webcam to pan/tilt while tracking a face in real time using the raspberry pi not as impossible as it may at first seem. With some careful tweaking and code optimization I was able to allow the pi to keep up with two

Design Required 2 x DS18B20, 2 x 4.7k resistor The DS18B20 is a rather useful sensor because you can read more than one of them using the same GPIO pin. The Raspberry Pi is able to recognise the input from each separate sensor. This system is called “1-wire”, although the sensor still needs power and

If you want to build electronic devices, at some point you’re going to need to read data through GPIO. In this exercise, we’re going to read the value of a push button on a breadboard. Set up the circuit as shown in the pictures on the right. Note that one end of the 4.7kOhm resistor

This example shows how to use Raspberry Pi® hardware to interface to a motion sensor and control an external LED. Introduction Raspberry Pi target enables you to create and run Simulink® models on Raspberry Pi hardware. The target includes a library of Simulink blocks for configuring and accessing Raspberry Pi peripherals. In this example

Adding an Envelope Detector to convert an RF input to a DC output I connected the ADC Pi module to the GPIO header and stacked the DDS module on top. PCB support spacers were used to hold the modules together and to take the strain off the GPIO pins. All that was left to do

Software Topology and Theory of Operation OpenPnP is the high-level brains of the machine, that does the seemingly-simple stuff like “pick up that part” and “put it over there”. Lots of libraries and sub-systems feed information to it, and it passes information to the various motors and actuators via other libraries and software modules. It
