@clarry290 Unfortunately we do not offer lessons for the use of that particular block with CoDrone Lite. However, we have made lessons for using the sensor blocks with our newest product, CoDrone Mini. Those lessons will be released by the end of this month. Although the Blockly environments are slightly different, you can use the CoDrone Mini lessons as a guide to get you started. I will let you know when those lessons are live. Thank you for your question!
