Since I have had a number of problems with the last circuit, I had to take all the wires out from the circuit, sadly. Fatal one is the LED needs 380mA and Arduino takes only 40mA by having a couple of office hours.
Now, all of the wires are rewired and then I separated the circuit for LED with transistor. The wiring was a bit still messy…;;)
Yet, it was successful …that it lit up. From tomorrow morning, I need to connect with Arduino(tweak the code a bit) and hopefully connect with Max to manipulate something(and do troubleshooting with that…) with this…!
