Fig. 1: Transmitter circuit
Fig. 2 shows the receiver circuit. It is built around IR receiver module TSOP1738, two BC548 transistors (T6 and T7) and a few discrete components. In the transmitter circuit, there are two astable multivibrators. The first, built around transistors T1 and T2, produces a frequency of about 1.2 kHz. The second, built around transistors T3 and T4, produces about 38 kHz. IR LED1 is used to transmit the 38kHz frequency.

Fig. 2: Receiver circuit
In the receiver circuit, TSOP1738 receives the IR signal transmitted by IR LED1 of the transmitter circuit. The output of TSOP1738 is fed to transistor T6 via diode D1. The amplified signal is further given to relay-driver transistor T7. Relay RL1 energises to control the toy car.
Working of the circuit is simple. Initially, when no IR beam is falling on sensor TSOP1738, the relay remains de-energised and the toy car doesn't move. When switch S1 is pressed, the IR beam falls on TSOP1738 and its output goes low. Transistor T6 cuts off and transistor T7 conducts to energise relay RL1 and move the toy car.
Assemble both the circuits on separate PCBs. Enclose the transmitter PCB in a suitable cabinet, with IR LED1 affixed on the front side and switch S1 on the top of the cabinet. Keep the 9V battery inside the cabinet.
Enclose the receiver PCB inside the toy car, with TSOP1738 fitted such that the transmitted IR beam directly falls on it. Fix switch S2 on the body of the car and the relay inside the car. Use a 6V battery to operate the toy car receiver unit.

hello its only one moter ckt i want a driver ckt for at least 2 moters.
is there any circuit which can control atleast 2 motors
let me know the clt diag in which tow motors are used n dey can rotate clkwise n anti clkwise
how do you employ the reversing mechanism?
I like it too much
IWANT CIRCUIT FOR A TOY CAR TURNING LEFT AND RIGHT THROUGH RC BY USING 4MOTOR
help me out for making mini robot carsmall vehicle using microcontroller
can i get d list of components required for making d transmitter n receiver circuits
just mail me your email id i will give you the details
dear send the components list to me ppakbarali@gmail.com
please clear that which two wires are actually connected and which are overlapping each other....and there is no capacitor of .01 ohms available in the market
First part of your query is not clearly understood. If you are talking about the motor supply wires, the two wires can be connected to a 6V or 12V DC source depending on the motor used. Both the values of capacitors C1 and C2 should be read as 0.01uF instead of 0.01-ohm. These values will be corrected very shortly.
Sir this circuit is for one motor i want to drive two motors either in clockwise and anti clock wise direction please help me ...
can you explain how can i modify this circuit for front wheel controls...
i want to operate 2 motors that too both reverse n forward direction.cud any1 pls gimme a list of components required and how to assemblejoin them in a circuit?pls respond at simardeep.mendhiratta@gmail.com
Superb circuit
