At Freetronics we love it when our customers share with us what they have created with our products. Ben Lennard from Lennard Electronics recently got in touch and shared his great project. Using four Freetronics dot matrix displays, Ben has built a sin bin management display for the National Hockey Stadium in Wellington. Whilst the system is used to display the time and various advertisements, the primary use is to keep track of how long different players have been in the sin bin. According to Ben, the affordable price, existing code libraries and the fact that the displays were bright enough to be visible from the other side of an outdoor hockey field, made our displays the perfect choice for his project!
Ben’s project uses four DMD's which are chained together and controlled by an Arduino Uno. The Uno receives commands from a Raspberry Pi powered touchscreen controller box, via a Bluetooth link. The outdoor display is housed in a custom built fiber glass case, which has special vents built into it to allow air to flow in and out whilst still keeping dust and water out. Thanks Ben for sharing!
If you are impressed by this project why not checkout our range of displays? They are simple to use, yet very bright for indoor and outdoor situations. Available in various colours, the 32 x 16 LED matrix can display text and graphics easily, and can be daisy-chained together for extended displays.
