Current Progress

Below is a list of my current progress.

1. Line follower

• It is working, but I will need to keep testing it to make sure that it is REALLY working.

2.  Serial communication between my Arduino Uno and the Arduino on Redbot

• This one is tricky
• I know how I can make a serial communication between these two, but the problem is I will also be connecting my Tx and Rx on my Uno to the Bluetooth module to allow Bluetooth communication.
• Now I am not sure how to connect these 3 things together. 

3. Communication using IR LED transmitters and detectors. 

• I am able to use multiple pairs of these to get different "pattern" of signals. 
• However, I am currently trying it on my Arduino, I am yet to transfer it to using just batteries. 
• I am also currently testing on how close each pair should or shouldn't be to avoid interference.

4. Bluetooth communication

• It is working fine.  

THE CHALLENGE IS PUTTING EVERYTHING TOGETHER!
