Students place electronic components and learn soldering skills with this hands-on circuit board kit. By placing a variety of components – transistors, capacitors, LEDs, and resistors – and soldering them in a functional circuit, students build a robot board with intermittently flashing LEDs. All components, including the circuit board, are included along with step-by-step instructions. Requires 9 V battery and diagonal pliers, sold separately.
