Using IR Remotes in Place of Mechanical Switches

• Physical switches and pushbuttons are commonly used to control devices and
  influence program flow . . .

• An IR remote provides a flexible alternative to hard-wired switches.
  For example, a 44-button IR remote requires only a single Arduino input pin . . .

• The following discussion explains how we can use an IR remote in place of physical switches in our projects.

Using IR Remotes in Place of Mechanical Switches

Using IR Remotes in Place of Mechanical Switches Physical switches and pushbuttons are commonly used to control devices and influence program flow. Each physical switch requires its own GPIO input; for example, five switches consume five Arduino input pins. In addition, mechanical switches are prone to contact bounce and are best handled by detecting "state changes" rather than continuously reading their current state. An IR remote provides a flexible alternative to hard-wired switches…
