Project featuring stopwatch based on Arduino nano and DYI 7 segment clock with max7219 and ULN2803A transistor array. For comunication project uses nRF24L01. #Arduino #Nano #Shield #project #nRF24 #max7219 #ULN2803A #Stopwatch #Firefighting_sport

Template for Arduino Uno R3 Shield. Include an official pinout so you will always know Arduino names, the alternative roles of pins, which one is SDA, or SCL, etc. On PCB you can find the 3D model of the Arduino Uno R3 itself along with the board outline on the silkscreen. #Arduino #Uno #Shield #Template #project-template #project
