Arduino - Touch Sensor - Relay
We are going to learn how to:
- Turn on relay if the touch sensor is touched.
- Turn off relay if the touch sensor is NOT touched.
We will learn how to toggle relay each time touch sensor is touched in Arduino - Touch Sensor Toggles Relay tutorial.
By connecting relay to light bulb, led strip, motor or actuator... We can use the touch sensor to control light bulb, led strip, motor or actuator...
Or you can buy the following sensor kit:
