This Instructable shows the steps I took to build my own open source theremin (Open Theremin) when there was none available to buy online. The lovely thing about open source is that the plans are freely available to make and modify. A theremin is an electronic musical instrument that you play waving your hands in

We enjoy having an ordered, methodical and efficient lifestyle, however, more recently we have acquired a taste for the disorganized, topsy-turvy, chaotic lifestyle. Which is why, in this Instructable we attempt to address our new found love for chaos by building a simple machine to visualize the effects of chaos. We used the power of

Introduction ESP-MESH is a networking protocol built on the top of the Wi-Fi protocol. ESP-MESH allows numerous devices (generally referred as nodes) spread over a large physical area to be interconnected under a single WLAN. ESP-MESH allows multiple nodes to communicate with each other under a single wireless local area network. It is supported on

This simple Arduino project can be placed in the doorway of a shop or other venue to count the number of people inside. Limiting the number of people inside a space can help to maintain social distancing. A demonstration of this project can be found here. There is no soldering required in this project, since all

Introduction There are probably over one-hundred Arduino based plotting machines on the internet with instructions available on how to make them. What makes this one unique (as far as I know), is the inbuilt camera and screen. Other plotters must be connected to a computer. This one works completely independently. The 20fps video shown on

In Today’s Tutorial, we will learn how to make our plant talk using Arduino nano with the MP3 player module. Basically, we will connect 3 sensors to the Arduino module: LDR Sensor. Capacitive Moisture sensor. DHT22 Temperature and humidity sensor. We will read the sensors values in Arduino and define the limits for each sensor
Let Your Plant Talk Continue Reading
Height is a major concern in public places. Kids affected more in public places due to height problem. The problem places due to height concerns are 1) First place is school from kg kids to High school kids, so lot of height variation so using wash basin, now a days while enter using hand sanitizer.

Introduction / Why this project In 2016 I build my first fish feeder, see Fish Feeder 1. The feeder worked fine for more then half a year. After that period the servos were worn out, causing the program to halt, without sending an error-mail. Oops. I didn’t had the time to correct this fault, because the aquarium
