LCD Working

LCD Problem

• LCD was not turning on
• Arduino on light was dimming off when connected to power

Fixing Issue

• Unplugged wires LCD module wires from arduino and breadboard

• Found out that I switched VDD and VSS pins (5V and GND)

• I tried to put the module back, but when connected to power module heated up

• Put the module in the write position

• added resistor for Anode

Text

• Learned about lcd.setCursor()

• Learned about how cursor and clear works

• learned about character, row and column

• Made text sync with the light, so when says 3, red light, 2 yellow light, one yellow light, go green light

Need to improve

• Put a real timer??
• Put button on breadboard
