Arduino Uno Servo Tester Kit: Test Any RC Servo in 3 Modes, All Parts Included

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Stop guessing if a servo still works. Whether you salvage parts from old toys or verify a fresh batch before a critical build, this Arduino Uno kit puts a complete servo test bench on your worktable. Turn a knob for manual angle control, launch an automatic sweep to check travel limits and smoothness, or read the exact pulse width in microseconds on a bright OLED screen - switch modes at the press of a button.

What You'll Build

You'll wire up a modular tester that accepts any standard hobby servo (like the included SG90 and MG996R). The 0.96-inch OLED displays the current mode and pulse data, the potentiometer gives real-time manual rotation, and three tactile buttons let you jump between modes instantly. In 2-3 hours, you have a troubleshooting tool you'll reach for every time you design a robotic arm, RC plane, or sensor-controlled actuator.

What You'll Learn

• Controlling servo motors with Arduino's PWM signals and the Servo library
• Reading analog potentiometer values and mapping them to 0-180� rotation
• Interfacing an I2C OLED display to show live pulse width and mode information
• Using push buttons with pull-down resistors to trigger event-based mode switching

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

CBSE Class 11-12 science students building robotics projects, B.Tech ECE/EEE undergrads practising servo interfacing, and ATL Tinkering Lab innovators will find this a practical starter. Maker clubs at IITs, NITs, VIT, and BITS use similar setups to audit servo performance before competition robots. If you have a box of servos of uncertain origin, this kit helps you separate the good from the glitchy in seconds.

Built and Backed by Compoden

Every Compoden kit ships with an AI build companion trained on this exact project - accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
