| − | Simulation macros are a form of Component macros. Their purpose is to make simulation more realistic by adding physical components to the electronic devices.
| + | For an excellent introduction guide, we recommend [https://www.flowcode.co.uk/education/ Introduction to microcontroller programming] |
| − | | |
| − | 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.
| |
| − | * Drag the mouse cursor over these three elements and group them together.

| − | Also on the System Panel, create an intruder, by:
| |
| − | : adding four spheres, and configuru=ing the properties as follows:
