Use a light to change the pitches played by three Circuit Playground Express boards.
We've created a theremin with variable pitch and volume without any of those nasty electric fields.
Combination of an Arduino Uno and ultrasonic sensor for security in different ranges.
When the light is on, there is no move from the servo. When light is off, the party mode begins, the servo lights up and the LED-S show off.
Simple portable USB scale to be used as a kitchen or industrial scale, supported with PC software for setting and showing weight readings.
What is in the red suitcase?
A device that follows the evolution of an ecosystem through different variables like temperature, humidity and sun exposure.
Whenever any vehicle passes through an IR sensor, the street light will turn OFF.
Using LM35 sensor and Bolt WiFi module, we can build a monitor that sends SMS/email whenever it detects an anomaly.
This sensor is used to record temperature values of a particular environment and other HVAC applications.
In this project, bring your hand puppet to life with Hexabitz modules.
This project will be utilising the Zio Qwiic Ultrasonic Distance Sensor to detect and track a person.
NB-IoT data transmission how to use BC95G modem based shields - NB-IoT upload sensor data to cloud using UDP and JSON.
Our device was a self-powered, wireless sensor node for use in Internet of Things applications.
Whenever a certain object is brought closer to an ultrasonic sensor, the LED will start blinking and the buzzer will also beep.
At operation of the gas sensor, the relay blocks gas and disconnects electricity in the house.
In this project we will monitor the room temperature using a LDR_NSL19_M51 light dependant resistor (LDR) and 4Duino.
It monitors Fridge's temperature and alerts via Telegram, if the temperature falls below thresholds. It alerts if someone opens the door, too.
The kitchalarm notifies you when your kitchen is empty so that you don't have to stop working to check for yourself.
Sending NCD IoT Long Range Wireless Vibration and Temperature data to google sheets using Node-RED
With N2L you are able to find fast and easy a learning spot as you desire.
Make your own DIY Halloween Town for Halloween using some previous projects and a DIY PIR sensor activated jack-o’- lantern.
