Adding some more components that demonstrate the versatility of the Arduino Uno
A potential divider that is a mechanical variable resistor.
Adding a simple button may not seem very challenging but there is more to this than meets the eye (or finger)
Think parking sensors for a car
This is a 180˚ servo that sweeps backwards and forwards through that angle
We can measure the amount of light with an LDR
These tiny but useful displays are a great way to show data
This measures the temperature and humidity
