Example circuits workspace

Example circuits requirements

• work on 9V battery but remain 5V compatible (for easy Arduino integration).
• Breadboard build should be very clear. Use short wire bridges; as little loose bridges and dangling wires as possible
• Use standard/similar colors (Red +, Black -, same signals same color) so circuit flow is easy to follow.

Example circuits

Timing

555

• alternate blinking lights (astable)
• monoshot (monostable / delay)
• PWM

sensors

• LDR (LED lights depending on light)
• NTC (LED lights depending on temperature)
• Contact microphone (with piezo disc)
• Electrect microphone
• Heartbeat sensor
• Touch sensor (resistive)
• Touch sensor (capacitive)?

Actuators

• Beep (piezo)
• Amplifier (LM386)
• 10^0 LED
• 10^1 LED
• 10^3 LED ;)
• Heat (current source (e.g. with LM317))
