This said, I’m a bit concerned that the motor breakout is always powered on and not switched by a transistor or a relay, so I will most likely use a outlet timer to switch it on and off. There is a note about editing the code for Clockwise and...

* The BLUE & GREEN LEDs have a forward voltage of 3V, so we can link their cathodes directly to the transistors. * The red LED has a forward voltage of 1.8 volts, so we need to put a resistor on it to reduce the voltage from 3 to 1.8V. To...

KeyAll HV Case

From the Jackson Harbor website ( www.wb9kzy.com/keyallhv.htm ): The Keyall HV kit allows the owner of a keyer with a low voltage positive (NPN or n-channel MOSFET) keying transistor to drive the vacuum tube transmitters and transceivers of...

WiFi Controlled 160mm Butterfly Valve

The clean way to solve this is cutting the power to the servo after movement by using a relay or a transistor - however I did not do that. Or one could use higher quality servos or even locking servos. Or sometimes a pull-up resistor works better. -...
