RF Controlled Solar Powered Mini E-Ricksha

The Mini Solar E-Rikshaw with RF Control is an eco-friendly, wirelessly operated robotic vehicle powered by a 7.4V 2200mAh Lithium-Ion Battery and a solar panel. Designed for automation and renewable energy applications, this project integrates RF wireless communication, motor control, and solar charging technology for an efficient and remotely controlled rikshaw model.

Key Features:
✅ Wireless RF Control (433MHz) – Operates via an RF transmitter and receiver, allowing smooth remote control.
✅ HT12E & HT12D Encoder-Decoder ICs – Ensures secure signal transmission and decoding for precise movement control.
✅ Motor Driver (L298N/L293D) – Controls DC motors to enable smooth movement in all directions (forward, backward, left, right).
✅ DC Motors & Wheels – Provides efficient and stable motion for the rikshaw.
✅ Solar-Powered System – A solar panel charges the 7.4V 2200mAh Li-ion battery, making it an energy-efficient and sustainable solution.
✅ Rechargeable Lithium-Ion Battery (7.4V, 2200mAh) – Lightweight and efficient, ensuring long battery life.
✅ Push Button Remote Control – Allows easy and intuitive operation.
✅ Expandable Features – Can be upgraded with obstacle detection (ultrasonic sensor), LCD display for battery status, and LED indicators.

How It Works:
1️⃣ User presses a push button on the remote to send movement commands.
2️⃣ The HT12E encoder converts button signals into digital data and sends them to the RF transmitter.
3️⃣ The RF receiver in the rikshaw receives the signal and passes it to the HT12D decoder.
4️⃣ The decoded signal is sent to the motor driver (L298N/L293D), which controls the DC motors and wheels.
5️⃣ The solar panel continuously charges the 7.4V Li-ion battery, ensuring uninterrupted operation.
