Arduino Genuino Uno by Arduino
Firmware
- Delicious Arduino Uno Version 6 (updated 2019-11-26)
- Wheel Encoder Firmware Version 3 (updated 2024-12-09)
Arduino Uno is a microcontroller board based on the ATmega328P and one of the most popular Arduino models. It has 14 digital input/output pins (of which six can be used as PWM outputs), six analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, an ICSP header, and a reset button.
The UNO can be programmed with the EZB firmware for various capabilities when connected to ARC. The tutorial to program the EZB firmware can be found HERE.

yes that is what i want to do
what is the wiring connection from the Adruino Uno (in this case) to the EZ
What kind of ezb are you using? But the wiring would be from the arduino uart to the ezb uart. The tx to rx. Rx to tx. And a common gnd. You can look at the data sheet for the ezb that you’re using to find the uart ports. They’re all different based on the manufacturer.
ahhh so same way to hook up a adruino to a maestro.. that makes sense... then in the script in the EZ, I can call an adruino function...
Not really. In the script in ARC you send a value. And on the ardunio the value gets read and calls a method.
electronics is like playdoh, and there’s no standard across companies or products. So it’s always a bit of research to get the info necessary to connect things together. In this case, you’ll be having an arduino be a slave to an ezb over a uart.
The arduino sits and waits for a value (command) to be sent over the uart. Then, the arduino calls the appropriate method by the value.
there really isn’t an easier way to do it.
if you’re wanting to connect a maestro to an ezb via uart, the same thing would apply. Connect the wires and send uart commands from arc.
TerryBau, using the Maestro servo Controller, Arduino, EzB, code, you got my curiosity, what are you building?
I use the ARC , Auto Position - Arduino and PCA 9685 for 16 servos
Like from ARC you send a value of 0 over the uart, the arduino will receive it and execute the myFunc1() method. Thats the example I posted above
you can’t call myFunc1() from ARC into the ardunio. That’s because once you compile the code, the myFunc1() is just a memory address and doesn’t exist anymore. It could even be multiple memory addresses if the compiler is smart enough to in-line. You can’t call a method by it’s name after it’s compiled to machine code. So you add IF conditions to call the method from a value.
ahhh that is even eaiser DJ
