Here, I am going to show you how to make a Clap Controlled Car without using Arduino, but by using IC 4017.
It's a car whose forward and backward movement can be controlled by a Clap.
This project is based on Clap ON - Clap OFF Circuit which is rendered to control the car using couple of relays.
It uses the ability of current to toggle between pin 2 and 3 of IC 4017 (on clapping) to be utilized in controlling the Car. Initially, one relay is active which moves the car in one particular direction; Giving a Clap activates the other relay which will make the Car to move in opposite direction.
Step 1: Materials Required
To make this Car, we require:
• IC 4017
• Relay 6V (2)
• Condenser Microphone
• Transistors – BC 547 (4)
• Resistors – 1K Ω (2), 100K Ω
• Diode 1N4007 (2)
• Motor with Gear
• Batteries 9V and Battery Clips (3)
• Quartz Clock’s Hour Hand Gear
• Pen’s Refill (2)
• Bottle Caps (4)
• Straws (2)
Major Tools required:
• Soldering Iron and Solder Wire
• Hot Glue Gun
Step 2: Circuit Diagram
This circuit is basically the extension of Clap ON - Clap OFF Circuit.
You can also make the circuit using IC 555, but it will require one more Relay. For more details of that circuit check out : https://www.instructables.com/id/Two-Clap-ON-Clap-...
