We bring you the Maker-UNO, an Arduino UNO compatible board designed and developed specially for students to learn coding and microcontroller. It is Arduino UNO R3 compatible, and by that, Maker-UNO can be programmed via Arduino IDE and compatible with all the example code and libraries for Arduino UNO.
We added a piezo buzzer that will act as simple audio output, of course you can program it. Yet, to ensure the compatibility of Arduino UNO, we have also put a slide switch to disable this piezo buzzer and leave the IO as it is. Aside from the standard LED on pin 13, Maker-UNO comes with a programmable LED on every digital pin, from pin D0 to D13. That is a lot of LEDs. We believe LEDs provide very good visual/light digital output where the eyes can observe, while piezo buzzer offers sound feedback where the ears can hear. That is good enough for outputs, how about input? We reserve the reset button and added a programmable button. How good is that? Now you can learn digital input, output, PWM (piezo buzzer and LED brightness) with just the Maker-UNO board.
Not to forget the change of FTDI chip to CH340 IC, the low cost yet stable USB to UART IC. Maker-UNO combines the simplicity of the UNO Optiboot bootloader (which load program faster), the stability of the CH340 and the R3 shield compatibility of the latest Arduino UNO R3. The USB MicroB socket for program loading and to power the board. Program can be loaded from your computer by utilizing your Android phone USB cable. Select “Arduino/Genuino UNO” for the “Board” in Arduino IDE and choose the correct COM port, you are ready to upload the code.
