Wireless DC motor controller

Description

In this kit, we are using RF technology to make a wireless remote through which we can control the DC motor in a definite range without touching for its different operations like direction and speed control. One can study the full operation of DC motors using this board. As it is microcontroller-based it can be programmable also and one can learn microcontroller interfacing with DC motor. Thus single-board serves the purpose of learning motor control as well as learning microcontroller programming.

Wireless DC motor controllers are two sections of this system; one is the transmitter end and another one is the receiver end. At the transmitter end, there is an encoder IC that encodes the 4-bit data and transmits it with a wireless device working at 315/434 MHz. At the receiver end, the RF receiver receives the data with the antenna and feeds these data to the decoder IC. The decoder IC decodes the data in 4-bit mode and the microcontroller checks the data sequence with these 4 bits.

The display unit is an LCD of 16×2 sizes. A wireless DC motor controller kit is used for proper user interaction. According to the control, inputs pressed on the remote the control parameters that is direction and duty cycle (for speed) is changed and the change is displayed. After this DC motor is commanded with the remote unit to operate according to set parameters for direction and speed.
