Easy to integrate
As a beginner, I was worried about compatibility. These plug right into standard breadboards. The sound and acceleration sensors added fun features to my smart home prototype.

Reliable and versatile
We use these in our university lab for introductory embedded systems courses. They hold up well to constant plugging and unplugging by students. Highly recommended for educational use.

Great value, clear documentation needed
The hardware quality is excellent for the price. All modules tested working out of the box. I wish there was a printed guide for the color recognition sensor, but I found examples online quickly.

Sonar module is surprisingly accurate
Used the ultrasonic sensor for a parking assist project. It's consistent and stable. The RGB LED module is also a nice bonus for adding visual feedback to projects without extra wiring.

Solid components for prototyping
Good build quality on the PCBs. The infrared modules are responsive. Only minor issue is the jumper wires included are a bit short for larger chassis setups, but that's an easy fix.

Perfect starter kit for robotics
I bought this set for my high school robotics club. The line tracking and obstacle avoidance sensors work flawlessly with our Arduino bots. The sensitivity adjustment pots make it easy to tune for different lighting conditions.
Q: Can I control the RGB LED module individually or is it pre-programmed?
A: The RGB LED module is raw hardware; it is not pre-programmed. You control the Red, Green, and Blue channels independently via your microcontroller's GPIO pins to create any color you desire.
Q: What is the maximum detection distance for the obstacle avoidance sensor?
A: The infrared obstacle avoidance sensors are optimized for short-range detection, typically effective between 2mm and 25mm. For longer distances, please use the included ultrasonic sensor module.
Q: Do you provide sample code for the acceleration sensor?
A: Yes, we host a repository with sample libraries and code snippets for all sensors in this kit, including the acceleration module, compatible with the Arduino IDE and MicroPython.
Q: Does the color recognition sensor work in complete darkness?
A: The color recognition sensor relies on ambient light or an external light source to detect colors accurately. For dark environments, we recommend pairing it with the included RGB LED module or an external white LED.
Q: Are these sensors compatible with 3.3V logic boards like the ESP32?
A: Yes, all modules in this kit operate within the 3.3V to 5V range, making them fully compatible with ESP32, Raspberry Pi, and standard 5V Arduinos.
