Serial_Servo_Arduino_Shield_Software

To support Arduino enthusiasts, we introduce the Arduino Serial Servo Shield. This versatile shield mirrors our serial servo controller's functionality, with two serial servo connectors, two programmable buttons, and a 1.14” TFT display for seamless integration and comprehensive feedback. Compatible with boards like Arduino Uno, Mega, ArdiPi, and Ardi32, it offers adaptable solutions for your projects.

This Github provides getting started guide for Serial Servo Arduino Shield.

Features

Serial Servo Shield with standard headers for Arduino and compatible boards
Jumper selection to switch between 3.3V and 5V compatible boards
TFT 1.14” display for user interactions
Two slot to connect Serial Servo Motors, and easily cascade servo to connect more number of motor*
Two Programmable Buttons to add additional control features to your project
Screw terminal and DC jack options to connect 6-8.4V adapter with onboard regulator
Power status LED to indicate board power.
Compatible Servo Motors =>
- SB-SS023 - For Lightweight Projects
- SB-SS15 - For Heavier Applications
- Servo Motor Key Features:
  - Real-Time Position, Load, Temperature, Speed, and Voltage feedback.
  - Servo/Motor Mode Switchable
  - High Precision And Large Torque
  - ID Range 1~253
  - 38400 bps ~ 1Mbps (1Mbps by default)

*NOTE: Avoid Connecting More Than 6 Servos At A Time, Not Recommended Due To High Current Demand By Servos.

1. Configure and Setup Development Environment

Download Arduino IDE from official site and install into your system. We have use Arduino IDE 1.8.19
Download library zip file provided here in github.
Extract and copy files inside Document > Arduino > Libraries folder. Make sure to restart Arduino IDE whenever you update or add any libraries.

Testing First Code

At this step you are all set to test codes, for easy getting started we have provided various demo example codes in github which you can download and try.
Open one example code in Arduino and make sure you have selected correct board with suitable com port, click on upload button to transfer code on Arduino UNO.
Since same default HARDWARE SERIAL PINS of ARDUINO used for INTERFACING SERIAL SERVO, so you have to REMOVE SHIELD BEFORE UPLOADING ANY NEW CODE.
Checkout other examples below and build your own custom program codes using those references.
