“Two months ago I was build Foosball table. It looks OK, but I miss Arduino. I didn’t like scoring units, so I was made electronic scoreboard. Main board I was chose Arduino Pro mini 5V. LCD display I was chose 16x02. For ball (goal) detector was used IR led for transmitter and TSOP34838 for receiver. 500ohm resistor it is for adjusting IR led. So if TSOP34838 didn’t detect IR beam adjust variable resistor.”
