Circuit shows the schematic of simple level translator based on very common transistors;
Nowadays most of the devices are running on 3.3 volts, and likewise their communication levels also work on 3.3 volts. For example XBee runs on 3.3 volts and to interface it with microcontrollers running on 5V, one needs to translated voltages levels so that they both communicate.
Parts Used:
- BC547 (2)
- BC557 (2)
- 100 Ohms (2)
- 47K (2)
- Interfacing XBee with PIC/AVR or any other 5V Microcontroller for UART Communication.
- Interfacing GPS Devices.
- Communication between 3.3 devices with 5V.

Microchip readers scanners are the devices vets use to extract the data from your pet microchip. The signal inside a microship of usually standard but if you are travelling, you may consider getting your own scanner to make sure the data are available everywhere.

Having a microchip cat flap has changed my life. The cat food was before simply vanishing and I had the feeling my cat was not the culprit based on his appetite when I was at home! Today I have the proof, I buy less food and he gets fatter!

Online gallery is beneficial for users to place an order of microchip cat flaps from shelter.
