+long-description                = """Blinking LEDs on Both Cores
+Updated Chapter 1 using the new
+light_tasking_rp2040 runtime - now with proper multi-core support,
+Ada.Real_Time, and delay until for accurate, slippage-free LED blinking on
+Raspberry Pi Pico.
+
+Contained in Chapter 01 reloaded are:
+
+1. blink - Jeremy Grosser Ada sample
+2. sketch_01_1_blink - Chapter 1.1 Blink internal LED
+3. sketch_01_2_blink - Chapter 1.2 Blink external LED
+4. double_blink-main - double blink using both cores.
+
+Read the full tutorial at [Chapter 1 Reloaded: Dual-Core Light Tasking -
+Blinking LEDs on Both
+Cores](https://pi-ada-tutorial.sourceforge.io/pico_ada_c01_blink_lt)
+
+> After quick community help, I rewrote Chapter 1 to use light tasking on both
+> RP2040 cores. No more manual timers - clean, precise dual-LED blinking with
+> zero slippage.
