Finally completed my wireless timer displays.
One remote control and two display units.
These operate up to a range of 75 meters (actually measured as over 200mtrs line of sight).
The remote control and display units are powered by Arduino Mega boards and I have written the software to drive the remotes LCD, keypad and radio and also the display units are interfaced into old commercially made displays that had failed.
nothing like breathing life into dead equipment and repurposing them.
I hope you like this.
The pulsing in the attached movie is due to the camera frame rate.
