About this app
Turn your Android mobile or tablet device into a powerful, universal remote control for your custom robotic hardware projects.
Visit https://spardynamics.com/#circuits-table to view the supported microcontrollers and boards. Support for even more microcontrollers and boards is being added regularly. Visit https://github.com/aditya-rao-iit-m/sparjoystick for the firmware and upload instructions for various boards like the Pico WH, ESP8266, ESP32, Arduino Nano, Arduino UNO, ESP32C3, ESP32S3 and future boards with Made in India chips. It is important to build the robot exactly as in the shared circuit diagrams for each board, and to use the exact firmware provided for each microcontroller type, at the link shared. Please turn off mobile data when using the WiFi option to prevent IP address mismatch issues.

The SPAR Joystick app is a versatile, high-performance controller designed for makers, robotics hobbyists, and embedded systems developers. Whether you are building a four-wheeled mobile platform, configuring a wheeled rover, or testing custom robotic systems, this app eliminates the hassle of writing complex custom UI code just to talk to your hardware.
This app runs on a well researched fast wireless UDP protocol developed and tested at IIT Madras by SPAR Dynamics, a startup incubated at IIT Madras. This fast wireless protocol can use any wireless transport layer. In this case, the app uses WiFi and Bluetooth to implement this protocol for fast response times and accurate control.
Equipped with a highly responsive virtual dual-axis joystick, it sends real-time coordinates over standard wireless protocols, making it instantly compatible with a massive ecosystem of microcontrollers and modules. The precision is comparable to hardware joysticks and this app implements reverse kinematics to control very tiny micro rc-cars to 1/8th scale formula racing kits.
