@Gordon sorry for later reply just .busy in work.
I just get my ESPRUINO PICO today. I happy to Draw ESPRUINO PICO if you want

Hi, Girdon
I have connected the tcrt5000 with espruino and use the pin c1 but the return value is just same.

Var light = analogRead C1);
SetInterval (function (){
console.log (light);
}, 500);

Is this code correct?

Hi, all
may I know how to use the Tcrt-5000 with espruino?
The link on the website is just intro the sensor?
Can anyone provide some idea and example.
Thanks.

Hi, all
I have a GH-311 ultrasound sensor and how can I use it? Because I only can find the HC-SR04 module in the website.
And when I using the HC-SR04 will get a error say Warning: Unable to set watch on pin.
Thanks

Dear Gordon,
I add the USB.setConsole () now my code is working good.
by the way may i know is this code mean?

Thank You

I have a code is working before but since the code is using Serial1.onData when i upload my code is get warning so i change the code above.

the older code

function onInit() { Serial1.setup(9600);}
var trace = "";
Serial1.onData(function (e) {
  print("--->"+e.data);
  trace = +e.data;

if(trace  == "1" ){
  digitalWrite(LED3,1);
}
if(trace == "0" ){
 digitalWrite(LED3,0);
}

});
save();

Hi all,
I using the following code to control the On board LED by the Bluetooth ,when using USB cable to power the code below is work .but when i unplug the USB and using battery to power up is nothing happen .

//Setup the BT Serial
function onInit() { 
  Serial1.setup(9600);
}

var trace = ""; 
Serial1.on('data', function (data) {

	trace = +data;
 digitalWrite(LED3,0);

if(trace  == "1" ){
  digitalWrite(LED2,1);
}
  
if(trace == "0" ){
  digitalWrite(LED2,0);
}
  
});

save();

@gnz I happy my Post is helping you, Good Idea Yes i should turning it into a tutorial.

@Pumych Yes, i using Fritzing and Illustrator for the circuits.

@Gordon Hi, I Found what is the issue .

is my fault when i solder the pin header to Espruino not correct. their still have some gap.

I have use a LED test by

digitalWrite

All PIN is working Fine Now

@Ducky Thank You for you information and reply.
@Gordon I found my problem but still have one issue for me.

First: in bread board, power circuit(+,-)is separated at half point so i need to make the far right two wire near.

The unsolved issue is i can't solve when i using [C6,C7,C8,C9] or [C6,C7,C4,C5]
the motor is not work properly.
Example if i using [C6,C7,C8,C9] and code like below . the motor should be stop,
but one of the motor is still working

var outputs = [C6,C7,C4,C5]; 
digitalWrite(outputs[0],0); // output 1
digitalWrite(outputs[1],0); // output 2
digitalWrite(outputs[2],0); // output 3
digitalWrite(outputs[3],0); // output 4

I need to code like below to stop both of the motor

var outputs = [C6,C7,C4,C5]; 
digitalWrite(outputs[0],0); // output 1
digitalWrite(outputs[1],0); // output 2
digitalWrite(outputs[2],0); // output 3
digitalWrite(outputs[3],1); // output 4

I have testing few hours in [C6,C7,C8,C9] and [C6,C7,C4,C5] this two group.
but the result is same all not work properly for me.

After few hours I change my Circuit PIN to B3,B4,B5,B6
Like the Attach Images below

and code like below is work properly for me

Both motor is Run

var outputs = [B3,B4,B5,B6]; 
digitalWrite(outputs[0],0); // output 1 
digitalWrite(outputs[1],1); // output 2 
digitalWrite(outputs[2],0); // output 3 
digitalWrite(outputs[3],1); // output 4

Both motor is Stop

var outputs = [B3,B4,B5,B6]; 
digitalWrite(outputs[0],0); // output 1 
digitalWrite(outputs[1],0); // output 2 
digitalWrite(outputs[2],0); // output 3 
digitalWrite(outputs[3],0; // output 4

I have No Idea why the PIN in the "C" is not working properly but the PIN in "B" is working Good?

I have Change my Circuit to the Following.
and update my code to

digitalWrite(LED1,1); //Check the Board is Word for LED

var outputs = [C6,C7,C8,C9];

digitalWrite(outputs[0],1); // output 1
digitalWrite(outputs[1],0); // output 2
digitalWrite(outputs[2],1); // output 3
digitalWrite(outputs[3],0); // output 4

But the Gearmotor is still not working

Hi, Ducky thank for reply.
you are right i miss connect GND and "Bat" to Breadboard.

I have capture a images for detail

Hello,

I using a L293D chip(16 pin) to control two 298:1 Micro Metal Gearmotor.
the following attach files is my Circuit.

Any i refer the http://www.espruino.com/L293D and write my code like below
but when send to Espruino to LED is LightUp but the GearMotor still not work is it any step i missing?

digitalWrite(LED3,1); //Check the Board is Word for LED

var outputs = [C6,C7,C8,C9];
digitalWrite(outputs[0],1); // output 1
digitalWrite(outputs[1],1); // output 2
digitalWrite(outputs[2],1); // output 3
digitalWrite(outputs[3],1); // output 4

Hi,Gordon.

I have Create Espruino Board In Fritzing. (link all the Connectors)
and i have email all the source files to you .
hope can help each other

ThankYou.
JackLee

i happy to share the .SVG Files and the .fzz

Hi,Gordon.
May i know Espruino have any Fritzing Files ?
i m using Fritzing to Design My Circuit.
i can't find any Fritzing in Espruino .com

Now i have capture photo with my own Espruino board and draw in Illustrator.
but i m beginner In electronic.how can i draw the Schematic and PCB?

ThakYou.

Hi,Gordon.
May i know have any Tutorial intro how to control a Micro Metal Gearmotor?
i m a beginner in Microcontroller where should i start Espruino? any opinion for beginner?
