Optimizing Light Controlled Bot Circuit for Improved Performance

In summary, the circuit works fine with a motor supply of 6 volts, but the counter clock is rising even at the falling edge of a light pulse, counting 2 pulses as 4.

Im working on a project which cycles through stop,forward, back,left, right modes of a bot using light pulses as input .
light source is laser pointer , room is dark
the circuit is not mounted on the bot
the circuit -
light pulse -> ldr-> bc337transistor ->7404 NOT -> 4017 decade counter ->7483 full adder -> l293d (10Volt)-> bot
bug - the 7404 inverter out is rising even at falling edge of light pulse
however it works fine with motor supply =6 v and also when dc motor is not connected to l293d
is the circuit correct?
schematic-https://drive.google.com/open?id=0B5m-h82V0Ej2N2kzVWE1UDR0WDg
any thoughts how to reduce noise in the circuit

any thoughts

post schematics in the thread
DONT force people to sign up to www sites just to see an image or 2

how are you going to the problem of ambient light affecting the receive side in the bot ?

that is going to be your first major problem

1. What is a light controlled bot?

A light controlled bot is a robot or machine that is designed to respond to changes in light or brightness. This means that it can be programmed to perform specific actions or tasks based on the amount of light it detects.

2. How does a light controlled bot work?

A light controlled bot typically uses sensors, such as photodiodes or light dependent resistors, to detect changes in light. These sensors then send signals to a microcontroller or computer, which interprets the signals and triggers the bot to perform certain actions.

3. What are some practical applications of light controlled bots?

Light controlled bots can be used in a variety of applications, such as automated lighting systems, solar tracking systems, and even in agricultural settings for precision farming. They can also be used in research and experimentation to study the effects of light on different organisms.

4. Can a light controlled bot be controlled remotely?

Yes, a light controlled bot can be controlled remotely using wireless communication technologies, such as Bluetooth or Wi-Fi. This allows for greater flexibility and control over the bot's actions.

5. Are there any limitations to using light controlled bots?

One limitation of light controlled bots is that they can only respond to changes in light, not specific colors or wavelengths. Additionally, they may not function as effectively in low light or dark environments. However, advancements in technology are continuously being made to overcome these limitations.
