Automatic control has always been the holy grail in the field of robotics. In this tutorial we will use a simple circuit to manually turn the Vibrating Brush Robot on or off with an infrared remote. Let us build the IR Remote Brush Robot from the basics right now!
- IC 555
- TSOP32138 Infrared Receiver
- Mini motor + hot glue stick
- Transistor 2N8050
- Soldering iron
- Hot glue
- 18650 batteries + holder
- Picture 1 is the easy version. To complete it, you only need to connect the vibration motor, switch and batteries
- .If you want to control it with a remote, you need to do a little more work. First, get a TSOP32138 transistor that reads IR remote signal, because it only reads 38 kHz infrared signal, other infrared signals will be ignored.
- Before receiving any IR signals, this transistor will keep emitting high electric potential, so we will need a second IC to reverse the signal, in order to start the vibration motor. We can use a 555 timer IC and set it to monostable, so that the UC only moves when we hit the IR remote.
- Lastly, if the signal from the IC is too weak, the motor won’t start. We can start an NPN transistor first, to gain enough current to start the motor.
