What to do ?
• Input from the mangonel sensors
• Input expected by the software
![Page 3: Welcome to the Real World](https://reader035.vdocument.in/reader035/viewer/2022062501/56816023550346895dcf261e/html5/thumbnails/3.jpg)
How to do ?
• Input arrives from sensors• Logic circuit combines and inverts inputs
to create a single pulse• PICAXE measures the pulse duration and
outputs the value to seven segment displays

Tips and tricks:• Be tidy: Keep the wires short. This improves
reliability.• Wire Colours does not affect the performance a
circuit, but does affect the performance of a person trying to understand it.
• Connected wires are marked with a dot.• Remember about the power supply.
– Do not forget to connect– Do not forget to switch OFF when making changes.
