I need to send data from Arduino Uno using laser to another Arduino Uno using laser sensor and oled.
The idea that i will write the data on the serial monitor for the transmitter and received it from the receiver and display the data on the oled. The problem is that i received data but no output on the oled and the serial monitor for the receiver display small square.
Can any one help me.
Thanks
Using the code tags, can you post your code so far?
Do like @hallowed31 says,
and show your wiring for both arduinos.
Sure, if you take the time to read the "How to get the best out of this forum" post, and add the required information to your post.
Search "arduino laser data transfer"... This one says it gets 10 bits per second. That's 75 characters per minute or 15 words per minute. lasermodem/lasermodem10.ino at main · KedalionDaimon/lasermodem · GitHub
