This is the project of infrared vision system for a toy car. It will project 2 modulated IR beams ahead and detect any reflection of these beams on any obstacle ahead of the car. The circuit will then invert the car’s motor for a given time thus changing the direction of advance as it goes in reverse. No special control for steering is necessary as the car has the front wheels’ shaft in an eccentric support: when going forward it autoaligns itself, when running backwards the shaft turns and the car describes a curve.[more]
This project build to drive a standard Radio Control (RC) Servo which is a motorized device that moves its actuator to a position specified by a controlling electronic signal. Inside is a complete servo system including motor, gearbox, feedback device (pot), servo control circuitry, and drive circuit. Several sizes of servos exist that range from very fast to very powerful. These devices were popularized by the Radio Control hobbyist movement and, as a result, are very inexpensive. [more]
How many times you needed some remote control to handle some electric device ? many times. There are lot of remote controls like infrared, RF, SMS (like my other circuit) and more. The basic small-range remote controls are 2, Infrared and RF (Radio Frequency). One of the weaks of Infrared is that the signal can not pass the walls. So, if you want to control your garage door, the only way is to use some RF remote control. The circuit (transmitter and receiver) use few components and ordinary . Its easy to build it because you don’t have to tune-up any coil or variable capacitor. The RF modules are fix to work in 418MHz area. [more]
The Arduino is sending commands (PPM-encoded series of servo-position pulses) to the RC transmitter (a Multiplex Royal Evo 12, in this case), which mixes them with manual input and radios them to the radio-controlled model.[more]
