Exercise - Using Simulation Macros
Simulation macros are a form of Component macros. Their purpose is to make simulation more realistic by adding physical components to the electronic devices.
When the Flowcode program is compiled and downloaded to a microcontroller, they are ignored - hence the name Simulation macros.
Even a cursory glance at the dialogue box used to configure them shows that they are very powerful devices, with a huge range of possible effects.
This exercise uses two of them to illustrate the use of a PIR (passive infra-red sensor) to operate an intruder sensor.
The physical background
The scene depicts the front of a house. A PIR sensor is mounted on the wall of the house, above the path leading across the garden. The data sheet for the PIR shows that it is sensitive to a range of 10 metres, within a cone of angle 100 degrees.
- On the System Panel, create:
- a brick wall, represented by a red rectangle, 15mm wide, 120mm high and 120mm deep, located at coordinates x = 10, y = 0, z = 60, with rotation settings X = 0, Y = o, Z = 180;
- a path, represented by a grey rectangle, 240mm wide, 100mm high and 0mm deep, located at coordinatesx = 140mm, y = 0mm, z = 0mm, with rotation settings of X = -180, Y = 0, Z = -180;
- a cone, couloured light blue, representing the sensing region of the PIR, with width = 70mm, height = 250mm, depth 95mm, located at coordinates x = 55mm, y = 0mm, z = 80mm, with rotation settings of X = 0, Y = 55, Z = 180.
