    Increase In Output Pulse As Supply Increases In 555 Timer, Why?

    one more thing, output of 555 timer without coin vibrating motor is 3.5v for 5v supply. but when i connect motor it reduces to 2.5v and causes less vibration. can i know why and how to overcome? i even tried using amplifier. also i tried using arduino with code(blinking led), without motor it...

    Help needed creating a toy train project

    ultrasonic sensor is used to detect walls, using its info you can control train, arduino is one of the open source cheap controller. costs around 500 rupees. you need to program it. you can get lot of tutorials of it on youtube. coding is very simple it uses mix of C C++ java

    Increase In Output Pulse As Supply Increases In 555 Timer, Why?

    This circuit is constructed using 555 timer for 1sec on and off delay, output of 555 timer was connected to coin vibrating motor through transistor. But as power supply increases from 5v on and off delay increases. Any solution for this issue???
