Read this page before you place an order NOTE: This scoreboard doesn’t have BLUETOOTH. It can only be operated with RF remote control This is a RF remote controlled do-it-yourself (DIY) digital scoreboard for indoor games. You can either order fully assembled scoreboard or DIY kit. Features: 2 players/teams Arduino based digital Scoreboard Size of displays: 2.3 inches. PCB Dimensions: 250.2 mm* 92.7 mm When scores are displayed from 0-9, the left digit is off. For example, if a team scores a 7, the scoreboard displays only 7, not 07. The scoreboard does not reset even if the Bluetooth is disconnected. Can be controlled with 4CH RF remote control The scoreboard works with 9V To build this scoreboard, we have combined three modules. RF module based controller: This is the central module of the Scoreboard. It uses a widely used 4CH RF module that communicates with a RF remote control. The central board communicates with two set of displays on its right and left side. The right display: The right display gets up and down count commands from the central RF controller. The left display: The left display also gets up and down count commands from the central RF controller. Power supplies: 2.3″ Scoreboard works with 9V-1A power adapter How does it work? To understand this working principle of Scoreboard, you need to understand two modules: RF module based controller: This is a basic RF based controller comprising NE555, CD4049 and few discrete components. It sends up and down commands to up and down counters placed on its right and left. Single-digit up and down counter module: I have described how 74LS192/CD40192 based up and down counter modules work. You need to combine two of the single-digit counters and connect them to the RF module based controller. The schematic of single-digit counter is here.
