+#X text 240 44 The Raspberry Pi Analog Input object allows for receiving
+analog data. It achieves this by leveraging Modern Device Lots of Pots'
+(LOP) onboard MCP3008 digital-to-analog converter.Channel -1 is reserved
+for "off" position. The remaining 8 channels (0-7) correspond to analog
+inputs (in order found on Modern Device's Lots-of-Pots shield). To
+change channel \, click on the channel number and enter new one (between
+0 and 7) or click on the number and while holding the mouse button
+down \, drag it up and down. If the object has successfuly connected
+to the desired analog channel \, the logo will light up.Once connected
+\, the object will output captured analog sensor data up to one hundred
+times per second with values ranging between 0 and 1023 (a total range
+of 1024).NB: Modern Device LOP board comes in two flavors \, equipped
+with 8 pan pots (one assigned to each analog channel) \, or as a "naked"
+(NOP) board that allows for easier access to pins.;

+#X text 240 104 The Raspberry Pi Analog Output object allows for sending
+analog data using GPIOs in combination with Pulse Width Modulation
+(PWM) algorithm. PWM produces values between on and off states by quickly
+switching on and off up to 1000 times a second. This is particularly
+effective when using the object in combination with an LED.Channel
+0 is reserved for "off" position. The remaining 10 channels (1-10)
+correspond to GPIO pins (in order found on Modern Device's Lots of
+Pots shield). To change channel \, click on the channel number and
+enter new one (between 0 and 10) or click on the number and while holding
+the mouse button down \, drag it up and down. If the object has successfuly
+connected to the desired analog channel \, the logo will light up.Once
+connected \, the object will be capable of sendin voltage to its output
+up to a thousand times per second with values ranging between 0 and
+1023 (a total range of 1024).;
