Netduino Connected Appliance Shield

Same code as example but with a scaled down single shield with 120 VAC in powering the Netduino and a relay to turn your appliance on/off.

Netduino Environmental Sensor Project

Sensing, power, air quality, temperature, humidity, and air pressure displayed on an LCD and transmitted by MQTT.

Helium Air Quality Sensor

A Helium-based air quality sensor and solar setup.

Smart Switch Using Arduino And Alexa

Temperature sensor is used to control a switch (relay) to turn on or off the device.

How To Make An Adjustable 555 Timer Relay Switch

Learn how to make a precisely adjustable timer with a variable delay from 1 - 100 seconds that uses the 555 IC. The 555 timer is configured as a Monostable Multivibrator. The output load is driven by the relay switch which is in turn controlled by the timer circuit.
