Not sure how old your son is, but when mine was 11 he got into making Roblox games, rather than just playing them. We did some of that Scratch stuff and the like years earlier but it didn't take, he ended up gravitating to it eventually on his own. He needed some help with the Lua language occasionally, but has done well copy-pasting and modifying bits of code. Now at 12 he splits his programming time between Lua/Roblox, C# (built a voice recognition "Jarvis" app mostly on his own) and some basic C to interface with Arduino components.
