Servo Tester

I dislike the cheap servo testers from AliExpress with a single button. When power is lost, they often switch modes automatically, which can cause damage. For example, if the tester switches to auto mode, it might trigger a full rotation cycle on the servo instead of staying in manual mode. To solve this problem, I designed a servo tester with fixed modes, selectable via dedicated buttons.Features- Neutral Mode: Sets the servo to 90 degrees.- Manual Mode: Allows you to configure the servo to a specific angle of your choice.- Auto Mode: Cycles the servo between the minimum and maximum values at a set speed. The device is operated with a rotary encoder. Pressing the encoder button cycles through the adjustable values, while rotating it adjusts the selected value.It is powered via USB-C and includes a switch to turn the servo on or off. The values are stored in the device. Required Parts1x ESP32-C32x 1kΩ resistors3x small switches11x 8mm M3 screws1x rotary encoder (EC11, 15mm shaft)1x 1µF
