This post describes how you can connect a real-world device with virtual-world of Proteus. The usage possibilities are unlimites and hence it breaks the unwanted-barrier between Proteus and Real World. COM Port Physical Interface Model which enables the “physical” serial port of your PC to available to simulation within Proteus. With it you can connect any of the “virtual” component found in Proteus with your PC Serial port. In other word this model connects your physical world with the Proteus-Virtual-World :) Continue reading

Circuit: Transistor based 3.3V-5V Level Translator

Post Thumbnail of Circuit: Transistor based 3.3V-5V Level Translator

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. This post gives a schematic of transistor based level translation with Proetus simulation. Continue reading

XBee and XBee-PRO 802.15.4 OEM RF modules are embedded solutions providing wireless end-point connectivity to devices. These modules use the IEEE 802.15.4 networking protocol for fast point-to-multipoint or peer-to-peer networking. They are designed for high-throughput applications requiring low latency and predictable communication timing.” (Digi.com – vendor of XBee Radios) Continue reading
