Wireless Foot Pedal

thingiverse

This is a foot pedal that sends out a signal when pressed. It transmits data on the 433MHz frequency to indicate that the pedal has been stepped on. It was designed to minimize the number of cables running around my workspaces and desks. The device uses an Arduino mini to control and send data to a receiver, which can be placed anywhere. The design is somewhat rough because I didn't invest much time in perfecting it or printing the parts. how it works There are two switches within the pedal: one for the power switch that allows the device to conserve energy when not stepped on, and another switch that signals to the Arduino that the pedal has been activated. A capacitor is connected to the Arduino to store energy and release it when the power is turned off. When this happens, the device sends data to indicate that the pedal is not being pressed while the capacitor discharges. The device runs on a small 12V battery, which powers both the transmitter and regulates the voltage for the Arduino at 5V. http://tinkersprojects.com/project/wireless-foot-pedal/ see more of what I've done: http://tinkersprojects.com/ <a href="https://twitter.com/TinkersProjects"><img src="https://tinkersprojects.com/wp-content/uploads/2018/04/download.jpg" alt="Twitter" height="70" srcset="https://tinkersprojects.com/wp-content/uploads/2018/04/download-300x110.jpg 300w, https://tinkersprojects.com/wp-content/uploads/2018/04/download-350x129.jpg 350w, https://tinkersprojects.com/wp-content/uploads/2018/04/download.jpg 370w" sizes="(max-width: 300px) 100vw, 300px"></a>
