From the project

A simple 555-timer-based servo tester designed in KiCad — generates a variable-width pulse signal to manually test and center RC servo motors without needing a microcontroller or transmitter.

- Pulse generator: NE555P timer IC (U1) configured to output a PWM-style signal on the SIGNAL pin - Pulse width adjustment: Potentiometer (RV1) lets you sweep the servo across its range by hand - Timing components: Resistors (R2, R3) and capacitor (C1, 22nF) set the timer's frequency and pulse characteristics - Reverse polarity protection: Diode (D1, 1N4148) on the power input - Power indicator: LED…
