In this video the squirrel jumps about 1.5 feet.
Previously tried rotating a tube feeder but high voltage is much better.
The platform feeder lets you see the birds better and the rotation sometimes sprayed seeds on the ground.
For those who prefer to use a $5 Sonoff switch:
"Hey Google. Zap the squirrel".
Update: Added DS3231 Real Time Clock and another relay to control a nearby fountain.
The RTC is used to turn ON and OFF the fence energizer and the fountain based on time in AUTO mode.
If AUTO mode is OFF the fence energizer and fountain can be turned ON or OFF manually.
RTC is also used to execute some code only once per second without using delays.
All my NodeMCU devices have RTCs. Default I2C connection is D1 and D2 to SCL and SDA on RTC.
Battery on RTC means power failures don't affect the controller time.
The date and time in the upper left of the web page HMI is coming from the RTC and only updates with a page refresh. The date and time below ZAP ON in the black font is coming from the internet and updates constantly.
Web page HMI is hosted on device for zero cost, zero I/O, high res, colourful display on phone, tablet or pc from anywhere on the same router using any browser. No app needed.
To display the web page HMI just put the local IP address of the NodeMCU device in any browser.
Web page HTML code is among the control code in Arduino IDE. Only web page address of the background JPEG is in the code not the JPEG file. Use client.println() instead of serial.println().
A wireless web page HMI is much better than an expensive, low res, monochrome LCD display only available wired near device.
