About using LED sensor to depict result of proximity senso

Do you see Developer Console icon on cloud home screen? If yes then it might be the control panel. I am not too sure about it but it appears in that way for older versions. For me also it is the same.

Hi ,
You can create your own custom function to read sensor data.

<script type="text/javascript" src="/serveFile?filename=bolt.js"> </script>
    <button onlick="digitalReadCustom(4,'output')"> Read sesor data</button>
    <span id="ouput"> </span>
    function digitalReadCustom(pin,element_id) {
            var xmlhttp = new XMLHttpRequest();
            xmlhttp.onreadystatechange = function() {
                if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
                    var obj = JSON.parse(xmlhttp.responseText);
                        document.getElementById(element_id).innerHTML = "Pin Val = "+obj.value;
                        if ( obj.value==0){
                            digitalWrite(5, 'HIGH');
                            digitalWrite(5, 'LOW'); 
                        document.getElementById(element_id).innerHTML = "Error = "+xmlhttp.responseText;
                        return "Error Occured"; 

Sorry , I was intending to answer another question but answered this.
