Many devices require input pulses for their operation. Some device requires continuous train of pulses some requires single pulse. In some of the devices there is a provision to alter between continuous pulses and single pulse. For example a stepper motor controller can have two operating modes – auto and manual. In auto mode it requires continuous pulses to rotate motor continuously while in manual mode it requires single pulse to be generated when button is pressed manually.

The circuit presented here is 2 in 1 circuit that generates low frequency pulses in the output. It has two operating modes. In auto mode it generates pulses continuously and in manual mode it generates pulse when push button is pressed. The circuit is built using single IC555. To generate continuous pulses it is configured in astable mode and to generate single pulse it is configured in monostable mode. 

Here we have presented a simple circuit using which you can convert IR signal into RF signals and at the same time transmit this to remote location and decode them using a compatible RF receiver. With help of this circuit you can increase the range of the device you are controlling up to 200 meters

The coin toss circuit is an interesting electronic project which can be used to conduct a toss between two teams or individuals.

 It is a decision maker used at the places where someone is not able to make up the decision. When a button is pressed, the head and tail h and t respectively display on 7 segment display.  An important feature of this circuit is using a single IC that is CD4049 and displays the h and t on seven segment displays in spite of LED so decision is clearly indicated.
